Level UP is a YouTube channel that focuses on humorous video game-based animations, particularly Super Mario Bros. and Pokémon, as well as other games. Some videos are short and standalone, while others are longer and have a sense of continuity.

Hallmarks of the channel include custom sprite animations, a focus on video game logic and crossovers between characters and genres, and a recurring Goomba and Koopa, as well as Freeze Frame Bonuses and minigames. Level UP is also affiliated with Hat-Loving Gamer.

The channel can be found here.

See also Team Level UP, the secondary channel where Level UP collaborates with other animators.

These videos contain examples of:

• Aborted Arc: The channel has left many stories unfinished over the years. For example, Mario's Balloon Cruise and Mario's Pokémon moves calamity both ended in a Cliffhanger, with the former explicitly teasing its next chapter, but neither has been followed up on despite having been uploaded in August 2021 and June 2018 respectively. The channel's very first story, Chiz the Cheese, never got past the second episode.
• Accidental Murder:
  • In "When everything Mario jumps on E X P A N D S," Mario abuses his Superpowers for a Day to make a gold coin enormous. He continues to stomp on the coin until it becomes so huge that it completely destroys Earth, causing literally everyone on the planet to lose a life, including Mario himself. The lives lost shown includes minor enemies, some friendly NPCs, Mario's friends, Princess Plum, and even Level UP himself. Waluigi in particular was on his last life when the world was destroyed and received a Game Over.
  • Bowser ends up on the receiving end during round three of Lucky Mario versus Impossible Mode Bowser, in which he gets smashed by a statue while he is attacking with fire breath. The camera then pans up to reveal that a Koopa Troopa who was piloting a crane lowered the statue too quickly.
    Goomba: "I said to lower it slowly, Koopa!"
• Accidental Suicide: During round 6 of Lucky Mario versus Impossible Mode Bowser, Bowser uses a massive axe to attack, but his axe ends up turning the bridge into an island, dropping him into the lava.
• Achievements in Ignorance: As shown in Goomba Revolution Shorts- Prank Wars!, apparently, using rollout can reflect magic, and no one but Hat Goomba notices.
• Action Bomb: Bob-ombs return, but this series introduces balloon enemies, which can explode.
• Actionized Adaptation: Red's Boulder Badge Calamity and Cascade Badge Calamity imagine the Pokemon world as having lethal obstacle courses to get a badge, with Red having to traverse pits, hostile Pokemon, and more.
• Adaptational Badass: Mario has several moves from different games including Super Smash Bros., Goombas know multiple parkour skills, and Koopa Troopas can throw their shells and catch them.
• All for Nothing:
  • The 2021 Christmas special involves Mario collecting a lot of coins to give Peach a Bowser repellent spray for the next time he tries to kidnap her...only for Bowser to reveal he'd built up an immunity to it and kidnapping her anyway.
  • Played for Laughs with "Mario's 1-Up Mayhem" where, after Mario has gotten plenty of extra lives to endure the deadly obstacle course, the course is finally shown to be MUCH easier than anticipated, and Mario doesn't lose a single life to it.
• All Just a Dream: In "When everything Mario touches GLITCHES", it's revealed that the crazy courses and challenges Mario did since the last God Mode Luigi episode were illusions within his subconscious. Meanwhile, God Mode Luigi continues his destructive rampage in the real world, and Level DOWN forces Mario to wake up.
• Alternate Continuity: For the most part, the Team Level UP videos aren't canon to the main series. Subverted with Rise of Hat Goomba, where it turns out that he's working with Gold Goomba, making him a Canon Immigrant.
• Alternate Timeline: "I animated MORE of your Mario ideas!" shows one where Mario actually managed to win against Eye-Patch Goomba and Paragoomba in "Mario vs the Giant Goomba Maze". In this case, they actually don't come back from their deaths, and a memorial is held by Gold Goomba in their honour. He then declares that they shall avenge the two fallen Goombas, now especially itching to kill Mario for what he did.
• And I Must Scream: At the end of "Battle for the Mushroom Kingdom," Luigi, upon being given the orders to do so, refuses to kill his brother Mario. As punishment, Level DOWN hijacks Luigi's body to kill Mario on his own.
  • There is also a scene in the video involving different types of Note Blocks where he hijacks Mario after the plumber bounces on a block that Level DOWN is pictured on. This is counted as a death.
• Anti-Climax: In Mario's 1-Up Mayhem, Mario sees at the start of a stage that the course is full of death traps, prompting him to go elsewhere on a hunt for extra lives. When Mario comes back, however, it turns out that the obstacle he saw at the beginning of the video, which he cleared first try, was the whole stage, causing him to remain on the flagpole with an awkward facial expression.
• Arc Welding:
  • The Goomba Revolution and the attack of Level Down, initially completely separate story arcs, are combined in Into the Void.
  • At the end of When everything Mario touches glitches, it's revealed that Mario's apparently self-contained adventures released after Battle for the Mushroom Kingdom actually took place in his subconscious as part of an attempt to hide from Level DOWN, which the latter calls him out on; thus connecting almost every video released in that two year timeframe to the God Mode Luigi arc.
• Area 51: "How will Mario escape from Area 51?" has Mario inside Area 51, depicted as a factory-like facility crawling with alien Goombas, where he's trying to find proof of aliens and escape.
• Armor-Piercing Attack: Level DOWN's forbidden technique God Mode may be powerful, but its Nigh-Invulnerability is no match for the power of a Gold Mushroom, as Gold Goomba demonstrates by knocking out two soulless Pokemon with God Mode activated at once.
• Artistic License – Physics: In the tomato sauce video, Mario fails a puzzle because he ate the meatballs he was supposed to drop on a nearby pressure plate, as his own weight isn't enough to activate it. However, realistically, Mario eating the meatballs should have increased his mass accordingly, allowing him to activate the pressure plate from the first attempt.
• Attack of the 50-Foot Whatever:
  • When Mario touches a Colossal Mushroom he grows so big, he straddles the planet. Later, Bowser does his best to stop him.
  • Balloon Bowser is a gigantic inflatable version of the Koopa King.
  • In one video, anything that Mario lands on feet first turns enormous. Emphasis on the anything, as this extends to inanimate objects, characters, and items.
• Audience Participation:
  • The outros of many videos prompt the viewer to subscribe to the channel in order to help someone, such as subscribing to heal a character that got injured during the video.
  • The one million subscribers video was a collaboration with fans, using many of their suggestions in the video.
  • Sir Buppington's name was picked from a response to a post on Twitter asking what to name the Toad Warrior.
  • "I animated your Mario ideas!" and its similar videos take ideas from YouTube comments and work them into little animations. There's also the odd occasion when some of these animations get expanded upon a bit, like "The floor is TOMATO SAUCE" and "When Mario becomes FIREPROOF!".
• Author Appeal: Some videos feature Ditto to some extent.
• Back from the Dead: Toadette wonders how she is alive when she is brought back by a 1-Up just after turning into a zombie in the second Mario and the Zombie Apocalypse video.
• Badass Normal: Eyepatch Goomba doesn't use any power-ups, instead using improved skills that most other Goombas don't know such as wall jumping and roll attacks.
• The Bad Guy Wins:
  • Mario Party Mayhem has Wario and Waluigi beat Mario and Luigi in a mini-game.
  • If Fighting Bowser Had An Impossible Mode 2 has Bowser defeat Mario on every single life. Balloon Bowser gives Mario a similar treatment.
  • A good deal of the shorts involving Baldi have him winning in the end. Averted in the Sonic short, where Tails is able to solve the impossible question and calm him down.
  • Mario fails to defeat the Goombas in the Giant Goomba Maze, letting them continue their revolution unopposed.
  • Bowser manages to give Mario a Game Over in the Cavern of Arrows.
• Bait-and-Switch: In 8 realistic ways to avoid Pokémon trainer battles, the third method says "using Fly". You might expect Red to fly himself past the trainer. Instead, he has his Doduo fly the trainer away to clear the path.
• Banana Peel: In Mario's Rising Lava Escape, one of the pillars Mario has to jump on has a banana peel on it. He fails to notice it and falls to his death; in his next attempt, he clings to the edge and pushes the banana off, clearing the way.
• Big Bad:
  • Magikoopa for the Mariocraft series.
  • Level DOWN, as it turns out, has been possessing Luigi for quite a while and granted him God Mode abilities. He was so good at hiding it that Luigi himself was unaware of the possession. He eventually takes action in God Mode Luigi vs. the Cavern of Arrows, where he banishes Level UP to the Void and later attacks the Mushroom Kingdom, taking many lives in the process. In later videos, Level DOWN is seen using his powers to mess with Mario, such as making green objects dangerous to the touch.
• Big Good:
  • Level UP takes on this role during the God Luigi arc. After being banished to the Void, he intends to make his goal to escape from it, recruit some allies, and stop Level DOWN from taking control of the Mushroom Kingdom. He ultimately takes action in The Goomba Revolution - Into the Void where he summons the top ranking members of the Goomba Revolution to fight off the Pokémon Soulless and enlist them to help save the world from Level DOWN, and then reclaim his channel from his evil counterpart.
  • Princess Plum also fills this role during the God Luigi arc. After Level UP and Wolfie get captured by the Soulless in Princess Plum vs The Soulless, she makes her goal to rescue them and aid Level UP escape from the Void in order to stop Level DOWN.
• Body Backup Drive: This is how extra lives work in some episodes. If Mario died by zombification, his old body will remain even when he respawns and it may try to attack him. One Mario zombie somehow even gets his own extra lives. Toadette also ends up suffering from this, leading to the creation of Zombie Toadette.
  • This also happens in Mario Can't Touch The Color Green!, where Mario ends up petrified if any part of his body touches an object that has the colour green, and his corpses become obstacles that he needs to avoid.
• Body Horror: One of the Cursed Mushroom effects has Mario's body fall apart pixel by pixel, while another turns him into a block. Similarly, Luigi getting the Weird Mushroom allows him to fold himself and stretch to uncomfortably long lengths.
• Boss-Arena Idiocy: Addressed and inverted during a video that showcases ways that Bowser can easily defeat Mario. In the third example, Bowser jumps on the axe that drops his bridge into the lava, and Mario falls to his death in the lava pool underneath.
• Boss Battle: These are common at the end of most animations. Bowser usually serves as the boss in the Mario-related animations, though there are times when this varies, such as Bowser Jr. or a Goomba Revolution member being the final threat.
• Boss in Mook Clothing: In Goomba Revolution related mazes, the maze bosses include professionally trained Goombas. To put in perspective, Mario ends up losing to Eyepatch Goomba (a basic Goomba) and a Paragoomba.
• Bumbling Henchmen Duo: Many videos feature a duo consisting of a Goomba and a green Koopa Troopa, whose antics, failed schemes and snarky dialogue provide comic relief.
• Burp of Finality: In "Mario vs. the Giant Bubbles Maze", Mario enters a ceiling warp pipe, followed by him screaming and his bones dropping out of the pipe. A Muncher plant emerges and burps to show that it had eaten Mario.
• But for Me, It Was Tuesday: Eyepatch Goomba had previously encountered Mario as a regular Goomba and isn't surprised when Mario doesn't remember him from back then.
• Butt-Monkey: Toads, Goombas, and Waluigi are often on the receiving end of comic mistreatment, and even when Waluigi wins he still tends to get hurt somehow.
• Canon Immigrant: Hat Goomba debuted in a Team Level UP video, which normally isn't canon to the main series. He makes his first appearance in the main channel in Mario vs the Great Pyramid of Goomba where he rescues Eyepatch Goomba from sinking into the lava after Mario beats him.
• Casual Danger Dialogue: At the end of "Giant Balloon Enemies would be OP in Super Mario Bros.", the giant balloon Bowser comes along to attack. Mario's last words before being effortlessly kicked off-screen by the inflatable titan?
  "Hey, let's-a play checkers!"
• Christmas Episode: Some shorts revolve around characters celebrating holidays, like Halloween, Easter, or Christmas.
• Cliffhanger:
  • Mario's Pokemon Moves Calamity and Red's Boulder Badge Calamity end on hooks for sequels.
  • Mario vs Bowser's Mega Submarine ended with a teaser for Mario's Balloon Cruise, which itself ended with a teaser for Mario and the Rainbow Road Express.
• Cliffhanger Wall: Installments can easily go several years without any new videos. MarioCraft took four years between parts four and five, for example.
• Continuity Nod:
  • If an animation that Mario or a Mario character goes through happens directly after a prior animation, expect them to have those remaining lives on hand once they get started.
  • Several places Luigi passes through in "Bowser Kidnaps Daisy and then this happened" are from older videos, including the Giant BOOM Box maze and the submarine video.
  • "Goomba and Koopa try to move Luigi" depicts how the events of the "Floor is TOMATO SAUCE" animation started (being when they accidentally threw a Mega Mushroom into a can of the sauce), and likewise how Luigi grew gigantic in time for that animation.
• Co-Dragons: Magigoomba, Eyepatch Goomba, Hat Goomba, Sea Captain Goomba, and a Paragoomba serve as these to Gold Goomba.
• *Crack!* "Oh, My Back!": In Every time Mario jumps, he gets older!, Mario tries to jump on top of a very high ledge, but cracks his back and falls into a Piranha Plant's maw. When he respawns, he snaps his back to fix it and successfully makes the leap.
• Creator Cameo: Nelly's (Level UP) Author Avatar appears in Zombie Mario's Maze Mayhem as one of the zombies Zombie Mario awakens.
• Cumulonemesis: The stormcloud area in "Mario's Balloon Cruise" is filled with little frowning stormclouds that periodically shock whatever's beneath them.
• Curb-Stomp Battle: The titular battle in the first episode of The Goomba Revolution starts out as one, with the Ghosts always able to respawn thanks to the center box, alongside Pac-Man holding out well against Gold Goomba, which gives the Goombas a lot of trouble. It takes Magigoomba locking out the box with a spell for things to finally turn in their favor.
• Damn You, Muscle Memory!: The "Every time Mario jumps, [x] happens" and "When everything Mario touches turns into [x]" videos use this trope for some of Mario's deaths and other mishaps, as Mario instinctively tries to clear obstacles the way he usually would, without realizing that his current gimmick will screw him over or at least get in the way.
• Darker and Edgier: Battle for the Mushroom Kingdom has a terrifyingly large body count for the Toads. While several Toads do the usual Death Throw, some Toads leave behind corpses, two of which Level DOWN sends to the void. Toadette in particular goes slack jawed upon being slammed into the wall lethally hard. Worse still, the whole thing ends on a Downer Ending, with Mario and Daisy on the brink of being finished off, and Luigi, trapped in his own mind, unable to do anything to stop it.
• A Day in the Limelight:
  • If Toad was the Main Hero of Super Mario Bros. has Toad in the starring role as Mario goes on vacation and Toad fights to save Peach from Goomba and Koopa.
  • Luigi's Balloon Cruise has Luigi in a starring action role as he battles a giant Bowser balloon.
  • Zombie Mario's Maze Mayhem has one of Mario's zombified bodies as the main character, along with other infected characters.
  • Goomba's Balloon Gets Stuck in a Tree stars a Goomba as the protagonist.
• Deadly Prank: In Super Mario Bros. but the floor is liquid nitrogen, a red Toad mischievously tries to push a blue Toad off the platform both are standing on and into the nitrogen. However, the latter (unaware of the attempt on his life) jumps out of the way at the last second, causing the former to keep going, lose his balance and fall off the platform himself.
• Death Is a Slap on the Wrist:
  • Characters like Mario and Luigi have several lives, as well as sometimes Bowser and certain enemy protagonists. Even if Mario loses all of his lives, he'll still be able to come back, but he'll be kicked out of the mission he's in and will have less lives when he continues. Seems to be averted in the Mariocraft and The Goomba Revolution story arcs, where in the former Mario and Bowser are actually in risk of getting killed by either Magikoopa or the Minecraft world, and in the latter, Bowser is temporarily taken out of commission for a while after being overthrown.
  • In some videos, especially older ones, Mario has no lives counter at all, with the screen after each death just reading "Mario start!", implying he has infinite lives. Similarly, the Pokémon calamity videos have Red respawning every time he falls into a trap, without any limit on lives.
• Defeat Equals Explosion: Balloon enemies explode shortly after defeat if they weren't already popped. Said explosion is also rather violent and can result in a Taking You with Me if the victim is within vicinity.
• Demonic Possession: In God Mode Luigi vs the Stone Statues Temple, it's revealed that Luigi himself is possessed by an evil entity that grants him godlike abilities.
• Didn't Think This Through: The Goombas in Level UP: Mario vs the Giant BOOM Block Maze realize that they have no way of leaving the BOOM Block after Mario evades them.
• The Dog Bites Back: The Goomba Revolution has Goombas overthrow Bowser and invade other games, starting with Pac-Man.
• Down to the Last Play: Maze levels and other challenges usually have Mario win on his very last life. Sometimes, he'll be able to survive with more than one, and in very rare instances, he can even lose that last life, resulting in a Game Over.
• Downer Ending: Mario fails to clear the Death Trap Mayhem, getting a Game Over right before reaching the flag. He also gets a Game Over in the Giant Goomba Maze as well as the Cavern of Arrows.
• Dude, Not Funny!: Level UP gives Bowser a Death Glare after the latter makes one too many puns to gloat over his victory. Bowser then promises to stop.
• Dumbass No More: Mario in Every time Mario jumps, he gets SMARTER! starts out lethally dumb but gets progressively smarter every time he jumps with the side effect of his brain getting progressively bigger, awareness of how the world operates and developing telekinesis.
• Early-Bird Cameo: In Stretchy Luigi's REVENGE, it's been confirmed that the volcanic location Luigi passes by is for the "Mario vs. The World of Fire" animation, which saw a release a bit over three years later.
• Early-Installment Weirdness:
  • Earlier videos had more blood as well as a tendency toward violent humor, while later videos have characters die like they do in the games and are more family-friendly. Some episodes still have Family Unfriendly Deaths though.
  • In its beginnings, the channel uploaded content from a variety of works, with Mario being slightly more frequent but not dominant. Over time, Mario got more and more focus, and nowadays the channel is almost exclusively Mario themed content, with the occassional non-Mario video once in a blue Moon.
  • The channel started out with a fully original work titled Chiz the Cheese. It was dropped after only two episodes, and the channel has only done video game fanworks ever since.
  • For the "Impossible Mode Bowser" series, the first episode; it ends with Mario, now on his last life, getting fed up and launching himself at the axe in a Death or Glory Attack, successfully making it across the bridge and dropping Bowser off the stage, albeit the latter survives by clinging to a wall. Later episodes simply end with Mario running out of lives, leaving Bowser as the winner.
• Enemy Mine:
  • Bowser and Mario team up in Mariocraft. Luigi, Toad, Yoshi, and Sir Buppington also team up with Ludwig and Roy Koopa of the Koopalings.
  • In the first episode of The Goomba Revolution, Pac-Man and the four Ghosts, normally never amicable with one another, work together to combat the common threat in the Goombas.
  • God Mode Luigi UNLEASHED features Bowser rallying Peach, Mario, and the Mushroom Kingdom to defend it against God Mode Luigi.
  • At the end of the fight between the top Goomba Revolution members and the Pokémon Soulless, Level UP enlists their help to join him, Wolfie and Plum in stopping Level DOWN. They initially refuse this call, though soon agree when Level UP makes it clear that Level DOWN will start attacking other universes after he's finished with the main one. Even Gold Goomba is quick to understand that Level DOWN is going to seriously jeopardise his efforts and make them All for Nothing if he succeeds.
  • Downplayed in the raining lava episode, where the various enemies across the level choose not to attack Mario, instead focusing on surviving the common threat posed by the lava. Mario, in turn, walks right past them without fighting them (aside from stunning a Dry Bones). A Bob-Omb plays the trope completely straight by outright helping Mario, informing him of a hidden block he can activate to cross over a pit.
  • In Mario vs the Radioactive Cheep Cheep Maze, Mario and a Goomba team up with each other to escape the titular Cheep Cheep, and stick together for the entire video. Only at the end card does the Goomba Goomba Stomp on Mario and does the outro.
• Enraged by Idiocy: In the Level DOWN arc, Princess Plum is enraged when Level UP summons a bunch of Goombas to take down the soulless Pokemon infused with God Mode. Said Goombas are the top ranking members of the Goomba Revolution. The Pokémon never had a chance.
• Extreme Omnivore: When Mario collects multiple Weird Mushrooms, he goes from eating Pac-Man dots to eating pipes, platforms, and Bowser's castle, as well as enemies.
• Even Evil Has Loved Ones: The zombies are surprisingly sociable with each other, even if only exclusively each other. Zombie Peach takes it a step further and gives the living Mario a cake.
• Even Evil Has Standards: In Every time Mario jumps, he gets older!, once Mario is at his oldest and needs a walking frame to get around at a sluggish pace, the enemies stop attacking him and instead start actively helping him complete the level. Even Bowser refuses to fight him, instead telling him that he should retire and walking him across the bridge— which results in Mario activating the axe, thus dropping Bowser into the lava pit. The channel has since done a number of shorts showing even more enemies helping old Mario in various situations.
• Evil Counterpart: Level Down is the evil counterpart to Level Up and uses his reality-warping powers to possess and destroy things instead of creating.
• Evolving Title Screen: This happens quite a bit throughout the Level DOWN arc. When Luigi first takes over, the intro sequence is changed to say "Luigi UP". After Level DOWN is fully introduced, the intro changes to his likeness. Finally, when Level UP regains his energy, he personally restores the Level UP intro screen back to normal.
• Face on a Milk Carton: Princess Peach shows up as missing on the back of Mario's cereal box, driving him to go rescue her again.
• Facepalm: In When everything Mario touches turns to stone, Mario jumps on a switch to press it, but it just gets petrified without activating, making it impossible to press. Mario then brings his palm to his face, petrifying himself as a result. (He is restored with a resurrection.)
• "Fantastic Voyage" Plot: Mario vs the Radioactive Cheep Cheep Maze features Mario being Swallowed Whole by a radioactive Cheep Cheep after getting shrunk down by a mini mushroom and traversing its innards as a dungeon with a friendly Goomba to escape.
• Fighting from the Inside: Luigi refuses to destroy his friends and family when ordered to, so Level DOWN assumes direct control. Despite this, he later resists killing Mario and frees an arm from the mind chains to give his brother a fighting chance.
• Flying Carpet: Mario turns Bowser into one with his newfound powers in Every Time Mario Jumps, He Gets SMARTER! when he confronts the Koopa King and answers a riddle but Bowser refuses to raise the bridge despite promising to. This is what allows him to bypass Bowser not raising the bridge.
• Forced Transformation: Occurs in some videos, like a New Super Mario Bloopers video where Mario touches a flower only to get turned into one himself, much to his chagrin. In another, he and Bowser are turned into a Mario/Bowser/Star hybrid when they get into a tug-of-war for a star. He also gets turned into a duplicate of Bowser in "What Really Happens When Mario Gets Cursed Mushrooms." He also turns Bowser into a Magic Carpet in Every Time Mario Jumps, He Gets SMARTER!, Bowser reverts back to his original form and swears that he will get revenge for it in the outro. Then there is When Everything Mario Touches GLITCHES!, where Mario turns two Goombas into creatures with his face by touching them. And in this video, Peach gets turned into a Goomba when Mario tries to retrieve her purse.
• Foregone Conclusion: Seeing that Mario mistakes a regular Magikoopa for the Big Bad of Mariocraft in a collab entry by Level UP, Mario and Bowser had already defeated Mariocraft's Magikoopa.
• Fountain of Youth: In Every time Mario jumps, he gets younger!, Mario unknowingly walks into a mushroom that causes him to age backwards as he jumps, becoming a teenager, then a child. By the end of the video, he becomes a baby, after which Yoshi finds him and carries him on his back just like in Yoshi's Island.
• Freeze-Frame Bonus: In How will Mario escape from Area 51?, when Mario collects the folder, the text reading "Mario found proof of aliens!" instead reads "ayyliens" for a split second.
• Fright Deathtrap:
  • A rare self-inflicted example when Mario turns everything to obsidian and enters a Nether Portal; the sights within are so scary he dies almost immediately.
  • In Team Mario's Mystery Pipes Mayhem, when the giant poison mushroom appears, Luigi drops dead from fear while everyone else runs away.
• Game-Breaker: In-universe, there's a collection of videos about characters being OP in Super Mario Bros and other games with videos detailing why.
• Glass Cannon: Balloon enemies can be easily popped by sharp or sufficiently heavy objects, but some of the bigger ones otherwise have little problem tearing through walls and will make their victims meet an explosive end.
• Gone Horribly Right:
  • The outro for Every time Mario jumps, he gets older! urges the viewer to subscribe to restore Mario's youth. However, it works too well and turns Mario into a baby, with the message "Too young!" appearing on screen as a result.
  • The outro for the next video, Every time Mario jumps, he gets younger!, does the same in reverse, telling the viewer to subscribe to make Mario grow up again, which turns him into an elderly man while a text saying "Too old!" is displayed.
• Greed: One of Mario's most notable character traits is his love for gold, which very often ends up being a Fatal Flaw for him and has caused a fair share of his deaths.
• Green and Mean: The zombies from the Zombie Apocalypse videos have a green colour.
• The Ground Is Lava: Some animations have this as a prime gimmick. Others swap out the lava for other nasty properties, such as acid, radioactive waste or even liquid nitrogen.
• Grow Old with Me: When Mario grows older the more he jumps, Peach uses an old mushroom at the end to grow old with him.
• Half the Man He Used to Be: At the end of Mario and Tiny Mario's Maze Mayhem, when Tiny Mario defeats Bowser, the axe splits him vertically. It's subtle and the viewer might miss it due to the dim colors used, but his second half lags behind his first as he falls into the lava and his brain is visible.
• Halloween Episode:
  • The Mario Goes Trick or Treating series has Mario and the Mushroom Kingdom inhabitants dressed up and getting candy, with special costumes giving Mario powers based on what he's wearing.
  • The Zombie Invasion has the revolting Goombas from "The Goomba Revolution" series having to survive a zombie invasion.
• The Heavy: While Gold Goomba does plenty of fighting himself, Eyepatch Goomba is the one to grief Mario the most often.
• Hero Antagonist: Some shorts feature Mario as the antagonist, such as Here's How Mario can beat the Impossible Mode Bowser shorts, with Bowser losing lives instead of Mario.
• Heroic Mime: Much like in canon, Mario doesn't speak in full sentences and only speaks in occasional catchphrases and grunts. He along with Luigi and Yoshi are the only characters to never have speech bubbles. Subverted in "If Peach and Mario switched places," "Mario Kart in a Nutshell," and "Mario's Mega Grrrol Escape". As of the latter, Mario is now fully voiced in a few episodes and in every outro where he appears.
• Hoist by His Own Petard: In Team Mario's Mystery Pipes Mayhem, at the second set of pipes, after everyone has chosen a pipe, Wario cheats by throwing Yoshi away to take his place... which becomes instant karma once Wario goes down the pipe and gets eaten by piranha plants.
• Hopeless Boss Fight: Impossible Mode Bowser invokes this, by using attacks and/or traps that would be straight out of a Platform Hell and often managing to defeat Mario because of this.
• Horrifying the Horror: In one of the comments animated in "I animated your Mario ideas!", after Shrek overpowers Impossible Mode Bowser without breaking a sweat, Level DOWN actually expresses shock and immediately shuts the adjacent door to keep Shrek out.
• Hostile Show Takeover: At the end of "God Mode Luigi vs the Cavern of Arrows," Luigi becomes too powerful for Level UP to despawn, defeats the creator, and takes over the channel.
• Hostile Weather: One episode has it rain lava, with Mario working with Bowser's minions to get to safety and beat the level before the lava overtakes them all.
• Identical Stranger: In Level UP's entry for one of his collabs, a normal Magikoopa is mistaken by Mario to be the Big Bad of Mariocraft.
• Inexplicably Awesome: Luigi can range from being a Butt-Monkey to being this depending on the episode. How much of this being a result of him being possessed by an entity giving him God Mode is unclear, but at least one scenario shows that he had 99 lives while everyone else besides Mario, Bowser, and Waluigi (the latter whom was on his last life) had two lives remaining.
• It Only Works Once: Every time Mario (or the main character of the episode) gets killed in a certain way by an enemy/trap, expect them to avoid being killed by that particular method from that same enemy/trap again. They can still be killed by the same enemy/trap more than once, but via a different method.
• Later-Installment Weirdness: In some later videos, Peach uses her Mystery Mushroom costume's sprites from Super Mario Maker as her idle animation and walking animations.
• Lame Pun Reaction: At the end of "Mario vs. The Cavern of Arrows" following the plumber's defeat, Bowser snarks that he's glad Mario got the point. Considering he made other arrow-based puns leading into the fight, it's no wonder Level UP's Author Avatar gives an unamused look towards him, prompting him to cut it out.
• Level Ate: Super Mario Bros., But the Floor is Tomato Sauce, a less hazardous variant of the recurring The Ground Is Lava gimmick. Not only is the floor coated in tomato sauce, but the level also has things like giant meatballs and spaghetti along it.
• Limited Wardrobe: Parodied in "Mario lost his hat and then this happened", where he has several identical overalls, but still goes through some of them before choosing which ones to wear this day.
• Literally Shattered Lives: Happens several times in When everything Mario touches turns to glass: first, Mario punches a Goomba repeatedly, first turning it to glass and then breaking it. Later, he comes out of a pipe and gets startled by an incoming giant cannonball, touching his own face in the process and turning himself to glass, after which the cannonball shatters him. Finally, during the tiny section of the level, he throws two glass Paragoombas, both of which break on impact: the first at a winged Bob-omb to detonate it, the second at a lever to flip it.
• Loophole Abuse: A common loophole in the When Mario Jumps series is that the condition only applies if he lands with both feet on whatever thing hes landing on, avoiding issues that way. He also cautiously drops down from ledges, as that also is not a jump.
• Losing a Shoe in the Struggle: In Lucky Mario's Death Traps Mayhem, a group of Munchers tries to eat Mario, but they only succeed in eating one of his shoes. Mario spends the rest of the level wearing only one shoe.
• Mêlée à Trois: While the Goomba Revolution has rebelled against Bowser, they remain hostile to the Mushroom Kingdom, resulting in a three-way conflict.
• Mercy Invincibility: Exploited in Mario vs Bowser's new castle. It's a rare instance of Mario reaching the boss with a power-up, so he simply damage boosts his way to the axe for a quick and simple victory.
• Midas Touch: This video has almost everything Mario touches turning into coins, including the ground, pipes, enemies, and spikes, though it doesn't save him from fire or spikes' damaging effects.
• Mind Over Matter:
  • In How will Mario escape from Area 51?, some of the Goombaliens encountered by Mario can use telekinesis. Alien Bowser has this ability as well, which he uses to crush Mario in mid-air. It's implied that this ability only works on airborne targets, as the aliens always use it when Mario (or in one case, his hat) is in mid-air, and the alien Bowser doesn't try to use it when Mario crawls past him.
  • In Every time Mario jumps, he gets smarter!, Mario eventually develops telekinesis, which he uses to lift the staircase at the end of the level and trigger the flagpole without jumping on it. This ability reappears in Big brain Mario would be OP in Super Mario Bros., where Mario uses it to defeat a squad of Bob-ombs by throwing various objects at them.
• Mini-Me: Some videos have characters and their Tiny counterparts working together to solve puzzles.
• Mistaken for Suicidal: When Mario becomes fireproof and lavaproof, he gets to an island where Toad and Toadette need a key that is floating above a lava pit. Mario dives in the pit to get it, but the Toads, unaware of his newly acquired immunity, assume he "took the easy way out".
• Mistreatment-Induced Betrayal: Nurse Goomba, who would normally antagonize anyone who hurts Goombas, refuses to heal them after they and Bowser arrest her for taking care of a Yoshi egg.
• Mook-Themed Level: "Mario vs the Great Pyramid of Goomba" is a parody of this sort of level, as the pyramid starts out completely covered in Goombas that Mario needs to find a path through and is filled inside with Goomba-themed traps, some of which use pits full of Goombas instead of lava..
• Mood Whiplash: At the end of If Luigi gets scared, he loses, Team Mario celebrates their victory... and then they suddenly start fighting each other for no reason.
• Mundane Made Awesome: This video shows the Mario cast in a game of checkers filled with epic music, strategies, and power-ups.
• Nice Job Fixing It, Villain!: In Mario's Lucky Star Mayhem, Mario is grabbed by a Scuttlebug, but before he can be pulled into the tree and eaten, a Goomba with a bow aims at him and misses, killing the Scuttlebug instead and saving Mario. The act itself of trying to shoot him was redundant, as Mario was already about to die even if the Goomba had done nothing.
  Mario: Thank you very much!
  Goomba: I wasn't trying to help you!
• Nintendo Hard: Invoked with the If Fighting Bowser Had An Impossible Mode videos, which show ridiculously hard Bowser fights that take all of Mario's skill to overcome.
• Non-Lethal K.O.: True to the spirit of the series, the Pokémon videos focusing on Red have him "blacking out" whenever he falls into a trap or gets attacked by a Pokémon. It gets exaggerated in Red's Cascade Badge Calamity and When spin tiles become 100x bigger in Pokémon; in the former, a Hyper Beam from a Gyarados visibly reduces him to a pile of ashes, while in the latter, he falls into lava; both get the message that Red blacked out, followed by Red respawning perfectly fine.
• No-Nonsense Nemesis: Mario vs Bowser's Mega Submarine has Bowser sink Mario's boat and kill him before he even realizes there's a threat. Luckily, a 1-Up revives him and lets him combat Bowser.
• No Ontological Inertia: In the "Mario can't touch [color]" videos, the episode's color loses its hazardous effects once Mario defeats the boss who caused them in the first place, with the exception of the green video, where the effect is instead removed by Mario reaching the flagpole.
• No-Sell: In When everything Mario touches turns to stone, Mario tries his Taken for Granite powers on a Thwomp. It doesn't work because the Thwomp is already made of stone.
• Not Completely Useless: In "Mario's Pokemon Moves Calamity," the near-useless Splash move is ultimately what gets him safely across a lava pit.
• Not So Invincible After All:
  • New Super Luigi Bloopers has the normally unflappable Luigi fail at winning by doing nothing.
  • Near the end of "The Zombie Invasion", Gold Goomba is knocked out by a few of the Toad zombies, forcing Magigoomba and Para-Goomba to carry him out of their reach.
• Not So Stoic: Zombie Mario's Maze Mayhem shows a zombie Goomba being saddened over being unable to jump high enough to reach a pipe. Zombie Mario promptly comes back through the pipe to help him through.
• Now You Tell Me?: Needless to say, in Level UP: Mario vs the Giant BOOM Block Maze Mario's quite disappointed when the game tells him to never hit or break the big BOOM block after he dies to it.
  Mario: Now it tells me?
• Oh, Crap!: Mario sometimes has this expression when he's about to lose a life. A fine example is when he finds himself in a room full of ignited Bob-Ombs.
• Open Sesame: Occasionally, in the absence of a lever to open a door, Mario will resort to saying "Open Salami". And it works.
• Original Character: In a first for the series, which tends to use existing characters or make new ones out of recolors, Level UP Vs. the Soulless introduces Princess Plum of the Moonlight Kingdom.
• Paper-Thin Disguise:
  • In "Mario Ate a Bowl of Cereal and This Happened", Bowser breaks into Mario's house while wearing a green cap and fake moustache, doing nothing to conceal his reptilian features, but still fools Mario into thinking he's Luigi.
  • In a later video, he's shown doing this again, this time with Mario's cap to go on a date with Peach.
  • Mario enters Bowser's new castle by wearing the shell of a Koopa guard.
• Plot Armor: Most named characters who don't have extra lives have this. Sir Buppington in particular gets launched away from the chaos during Level DOWN's attack on the Mushroom Kingdom, sparing him from a devastating ground pound.
• Race Against the Clock: Mario finds a Mega Mushroom but never stops growing has Mario slowly growing after eating a Mega Mushroom and having to navigate a level quickly before his new size turns against him.
• Ragtag Bunch of Misfits: Toad, Nurse Goomba, and Baby Yoshi team up to escape after Gold Goomba's army took over. They go further underground to the prison to bust out the rest of the prisoners and make an army to stop the revolution.
• Rapid Aging: As the title implies, this is the main gimmick of Every time Mario jumps, he gets older! Mario jumps himself to old age and becomes less and less athletic as a result, until he can barely walk and jump and needs the help of his former enemies (now unwilling to harm an old man) to reach the end of the level.
• Rapid-Fire Comedy: The "A Legit Speedrun" series specializes in this; think of Something About as a sprite animation and you pretty much have it.
• Ray Gun: "How will Mario escape from Area 51?": The Goombaliens in Area 51 use Zeerust laser pistols, which incinerate Mario when they hit him. He picks up the damaged ray gun of a defeated alien as one of the alien proofs that he's after.
• Reality-Breaking Paradox: In the video Everything Mario touches turns into Bowser (Animating your ideas 5), the first part had Mario having powers that turn everything he touches to his arch-nemesis. Once he goes into Bowser's castle, Bowser lampshaded that he's the only true King Koopa. He told Mario to not touch him with his powers as it would tear the fabric of reality. Once Mario touches him, Bowser duplicates into a diagonal parallax effect and the level glitches in the end.
• Recursive Reality: Mario and the Ladder of Worlds has ladders so huge each individual rung has an entire world in it.
• Red and Black and Evil All Over: Level DOWN is a malevolent, destructive monster. His body is black, and he has red eyes, and anyone he possesses can enter God Mode, gaining red eyes as well.
• Red Eyes, Take Warning: When Bowser kidnaps Daisy, Luigi's eyes turn red and he stretches himself to his limits to save her. It also glows whenever Luigi is about to use reality bending powers. Turns out that this is actually the result of Luigi being possessed by a malevolent entity known as Level Down.
• Resized Vocals:
  • Tiny Mario and Tiny Luigi (and, to a lesser extent, the Tiny versions of other characters) use high-pitched versions of the voice clips of their regular counterparts.
  • This also applies to objects, so when someone gets a mini 1-Up Mushroom or travels through a mini Warp Pipe, regardless of their own size, a high pitched version of their respective sounds play.
  • A visual version is used in Mario and the Radioactive Cheep Cheep Maze, where Tiny Goomba's onscreen dialogue is written in a thinner font than usual.
• Rise to the Challenge: Mario's Rising Lava Escape has him try to escape a vertical area full of rising lava. Mario's Rising Acid Escape employs this too, but with a pit full of rising acid.
• Rubber Man: Luigi gains these powers upon eating a Weird Mushroom and keeps them, even across lives, averting Status Quo Is God.
• Screw This, I'm Outta Here!:
  • When Level DOWN arrives with Luigi to attack the Mushroom Kingdom, Bowser retreats to his own kingdom to prepare its defences, leaving the Mushroom Kingdom to tend to their own. To his credit, he did at least give the Mushroom Kingdom a heads up of what's to come, and retreating was a smart move on his part considering how quickly Level DOWN is able to mow down the Toads.
  • At the end of Every time Mario says "Yahoo", he gets bigger!, Bowser sees how big Mario has become by the time he reaches the flagpole and gives up, signing over his castle to him and leaving in his clown car without a fight. This doesn't work out for him, however, as Mario then throws the castle at him before he can get too far away.
• Self-Disposing Villain: Mario eats a bowl of cereal has Bowser trying to overkill Mario in disguise, only to fall victim to his own machinations while Mario is completely oblivious.
• "Shaggy Dog" Story: Mario's 1-Up Mayhem has Mario seeing a difficult challenge and gathering many 1-Up Mushrooms to help him... only to learn the challenge was extremely easy and not losing a single life.
• Shout-Out: In If Luigi gets scared, he loses, Waluigi's attempt has him put on Eustace's mask from Courage the Cowardly Dog, complete with shouting "Ooga booga booga!" When it doesn't work, he drops the mask on the ground in disappointment and leaves; Yoshi then walks in, gets scared by the mask and screams while he gets a freaky animation similar to Courage.
• Signing-Off Catchphrase: In the outros of many videos, Mario appears and says: "Thank you for watching everybody! Don't forget to subscribe here to see more videos of me, Mario! I'll see you next time!"
• Skewed Priorities: In videos where Mario has to run away from a giant enemy or a hazard, he often dies due to going out of his way to get items. For instance, early into Mario's Rising Acid Escape, he takes a detour to collect coins and is unable to turn back before the platform he needs to get back in the right direction becomes submerged in the acid.
• Sound-Effect Bleep: In If Pokémon moves were actually realistic 5, Banette uses Curse, saying several expletives which are censored with bleeps.
• Space Episode: Several episodes take place in the depths of outer space, such as Pac-Man and the Asteroid Belt Maze having Pac-Man navigate asteroids, moons, and a planet populated by ghosts.
• Special Guest: Slick Frame, known for his Ask Mario series, voices Mario in the 200 episode special. Mario would continue to use this voice in later videos he appears in.
• Spike Shooter: Bowser is able to shoot the spikes on his shell (which are actually arrows) in the Cavern of Arrows video, which is how he gives Mario a Game Over.
• Spontaneous Human Combustion: Occasionally happens to Mario when he finds himself trapped in an unwinnable scenario.
• The Starscream: Through a well planned out takeover, an army of Goombas led by a Goomba who consumed a Gold Mushroom took out Bowser and stole his resources, intending to collect six artifacts from different games to take over the world themselves.
• Status Quo Is God: Averted with Luigi, whose Rubber Man powers gained from eating a Weird Mushroom are permanent.
• Stealth Prequel: Goomba and Koopa try to move Luigi initially seems like a perfectly normal video about the aforementioned duo trying to get past Luigi in order to reach a treasure. However, their final attempt results in them accidentally using a giant mushroom on a can of tomato sauce, setting up the events of the "floor is tomato sauce" video. This is what finally persuades Luigi to leave, himself becoming giant and setting up his role in that video, where he accidentally eats Mario while trying to inhale a giant loaf of bread; meanwhile, Goomba and Koopa get their treasure.
• Story Arc:
  • In Mariocraft, after Bowser killed his wife for failing to kill Mario, Magikoopa unleashes his rage onto the entire kingdom using the world of Minecraft.
  • In Goomba Revolution, the Goombas betray Bowser and seek to take over the kingdom by stealing six powerful weapons from different video games.
  • The God Mode Luigi arc, where Luigi became powerful enough to banish the creator to another dimension and take over the channel.
• Stronger Than They Look:
  • Balloon enemies and their attacks. They're rather light and they pop easily. The problem is, part of their strength lies in the fact that they pop easily since their explosion can result in a Taking You with Me.
  • In Goomba Revolution Shorts - Prank Wars!, a Goomba shows off the rollout attack that Eyepatch Goomba taught him to another Goomba. The other Goomba simply saw this as showing off. Hat Goomba attempts to prank on the Goombas using Magigoomba's stolen wand, but the Goomba using rollout ends up reflecting the magic projectile Hat Goomba shot and hitting Hat Goomba with it, turning him into a frog.
  • The higher-ranking members of the Goomba Revolution themselves. They may look like Goombas, but are much stronger especially when it comes to tactics — by working together, Paragoomba and Eyepatch Goomba in the Giant Goomba Maze manage to deplete Mario's lives and give him a rare Game Over. It's no wonder that Level UP decided to summon the Goomba Revolution to aid him and Princess Plum against the Soulless Pokemon, which they defeat without too much effort.
• Suddenly Voiced: Princess Plum vs The Soulless contains the first use of full-on voice acting in the series as Plum narrates her journey. Later episodes will have Mario himself have some voice lines outside of using clips from the games. A few Goombas also start speaking.
• Swapped Roles: Several videos are about characters switching places and roles, like Mario and Bowser and Mario and Peach.
• Taken for Granite:
  • In a video, Mario gets the power to turn anything he touches into stone. Well, almost anything: it doesn't work on Thwomps, which are already made of stone.
  • Also occurs in Mario Can't Touch The Color GREEN, where Mario must avoid touching objects with the colour green, and his body transmutes into an obstacle of the same material as whatever green object was touched.
• Taking You with Me:
  • Balloon enemies can take their adversary down with them due to their Action Bomb properties. Mario finds this out the hard way a few times.
  • On the ninth round in "Lucky Mario vs Impossible Mode Bowser", Bowser grabs Mario once he hits the axe, ensuring they both fall in the lava together. This earns them both a point, since this ended in a tie.
• A Taste of Their Own Medicine: Mario is occasionally stomped by the very enemies he stomps regularly, which costs him lives. In "Mario got stomped and this happened", however, this does nothing to hinder his progress.
• Taught by Experience: Whenever Mario (or the main character of the episode) gets killed in a certain way by a particular enemy/trap, they'll always avoid getting killed that same way by that enemy/trap in their next life.
• Temple of Doom: "Mario vs the Great Pyramid of Goomba" is set inside an elaborate pyramid filled with fire traps, winding chambers, movement puzzles, and tons of Goombas. When he sees it the first time, Mario faints in shock, which is counted as a death.
• Tempting Fate: In Mario's 1-Up Mayhem, two Goombas are hiding away a pile of 1-Ups. One of them boasts "Heh, Mario will never find these 1-Ups now!" right before Mario comes out of a pipe directly in front of them.
• This Is Gonna Suck: The 200th Episode Special opens with Mario seeing a huge gate and saying "Oh, I've got a bad feeling about this". Then he opens the gate, waiting for something to come out of it...and nothing. Then he has an Oh, Crap! expression before he gets crushed by the Mega Groll.
• Thousand-Yard Stare: Noted in the Among Us crossover video when Potato takes note of Luigi doing nothing but staring menacingly, with Mario saying it's just something he does sometimes.
• Throw the Dog a Bone:
  • Smash Kingdom Mayhem has Toad finally win at something by being the last person standing at the end of the fight.
  • In Sonic's Monitor Calamity, the last monitor Sonic opens contained the Chaos Emeralds.
• Timed Mission: The Giant Bob-Omb Maze has Mario having to escape before the fuse ignites and it explodes. There are other animations that have this as well, such as when a Hammer Bro is given access to try and strike the huge BOOM Block, Mario having to act fast to knock it into the lava before it can achieve its aim.
• Token Good Teammate: Nurse Goomba is a female Goomba whose job is to rescue flattened Goombas and nurse them back to health. She normally antagonizes anyone who attacks (or she thinks attacks) Goombas, particularly Mario. However, she is the only member of Bowser's army who cares for a lost Yoshi egg she found in a rainy day and she is jailed along with the egg for taking care of the offspring of a species that Bowser's army antagonizes, leading to her teaming up with Toad to stop the Goomba Revolution.
• Too Dumb to Live: Zombified characters tend to be unable to progress because they don't know that they can't jump. Either they're told by a more intelligent zombie how to do something or they learn through trial and error.
• Trial-and-Error Gameplay: Many of the traps Mario (or whoever else is the video's protagonist) encounters and dies to across levels are not telegraphed in any way, nor would a player have any way to know about them in advance or react to them if the levels were real, with Mario making it through the levels simply by having enough lives.
• Underestimating Badassery: Princess Plum is not amused when the Goomba Revolution Goombas heed Level UP's summons. They are actually stronger than she thought, however, as they proceed to mow down some God Mode Pokémon Soulless monsters.
  Princess Plum, when the Goomba Revolution Goombas appear: "They're GOOMBAS!!"
• Ungrateful Bastard: Bowser towards his tiny counterpart in Bowser and Tiny Bowser's Maze Mayhem; when Tiny Bowser can't push a block along, Bowser complains "Can you do anything without me?" despite the fact that Tiny Bowser had just gotten rid of an obstacle that Bowser could do nothing about by himself. Tiny Bowser angrily slaps him in the face in response.
• Uniformity Exception: Eyepatch Goomba is a Badass Normal Goomba who wears an eyepatch over his scarred eye.
• Unstoppable Force Meets Immovable Object: Lucky Mario vs Impossible Mode Bowser is essentially this as Mario's impossible luck and Bowser's unmatched skill clash in even matches.
• Villain: Exit, Stage Left: In Mario vs the Great Pyramid of Goomba, after Mario reaches the axe, the giant Goomba that Eyepatch Goomba is standing on starts sinking into the lava, but the latter warns Mario that this won't be the last time they meet, then Hat Goomba arrives to pick him up before the lava gets to him.
• Villain Protagonist: Some shorts star Bowser or his minions. The Goomba Revolution series in particular focuses on a group of traitorous Goombas who seek power from other worlds.
• Villains Out Shopping: Bowser passes time waiting for Mario with mundane activities like cooking, painting, playing games, and bouncing on the axe chain. In the video where Toad fills in for Mario, Bowser is similarly occupied waiting in line at the ice cream truck.
• Void Between the Worlds: Seen in The Void between Worlds, a dimension where objects and enemies from many different games appear. Stay too long, and you may end up losing your soul to a Soulless... unless you happen to be very good at surviving, which Level UP, Wolfie and Princess Plum all demonstrate effectively.
• Wham Line: In When everything Mario touches glitches, after Mario completes the level, the screen freezes. Then dialogue appears on screen in a very familiar looking font, accompanied by a very familiar speech sound effect, right before a reveal that recontextualizes everything Mario has been doing throughout the channel's last two years:
  Level DOWN: You are not really corrupted... are you, Mario?
• Wham Shot: A major one at the very end of When everything Mario touches GLITCHES - All the animations between the last episode of the God Mode Luigi saga and this one (complete with orbs as a Call-Back to several of these) were implied to be in Mario's subconscious, and Level DOWN shatters the illusion and forces him back to the reality of his situation.
• Wins by Doing Absolutely Nothing: Luigi has this as a trademark power. Other characters, such as Mario or Waluigi, sometimes attempt to copy his success but always fail.
• Womb Level: Mario has explored mazes on the insides of a giant Bob-Omb, a giant Goomba, a tiny Goomba, and a radioactive Cheep-Cheep.
• The Worf Effect: In Mario turned into a castle and this happened, the newly introduced Castle Mario proves how overpowered he is by getting Luigi to move while he was doing nothing.
• World-Healing Wave: In the lava rain episode, the lava stops raining once Mario reaches the flagpole, and the rising lava that was about to cause a flood recedes, saving everyone.
  • Also occurs in Mario Can't Touch The Color Green!, where Mario ends up making green objects safe to touch again by clearing the course after Level DOWN made them dangerous.
• World of Pun: Chiz the Cheese, the channel's first work, is set in a world of sentient food items who constantly make puns when talking.
• Worthless Yellow Rocks: In "Mario's World 1-2 Calamity", at one point Mario brings Samus to help him along the level. Then she takes the Warp Pipe to enter the bonus room, picks up the coins there, and... promptly shoots them before rejoining Mario.
• Your Size May Vary: Tiny characters can be anywhere from being proportional pixel-wise to the rest of the environment, to being smaller than a ground pixel.
• Zombie Apocalypse: The "Mario and the Zombie Apocalypse" videos have him and Toadette trying to survive an ever-evolving wave of undead, which are eventually led by Zombie Toadette when Mario gives Toadette one of his 1-Ups.
