Super Mario Logan (or SML for short) is a web series of various plush and puppet domestic Slice of Life situation comedy videos, made by Logan Thirtyacre and uploaded to YouTube.

The plots mainly focus on a variety of Super Mario Bros. characters, some other unusual choices (such as Shrek and Woody), and various original puppet characters and the mishaps they constantly get themselves into. For the most part, the episodes either focus on Mario and how terrible his life is, Jeffy and the utter havoc he wreaks, or Bowser Junior and the trouble he and his friends can never seem to stay out of.

In February 2021, Nintendo filed a cease and desist order against Logan for the usage of Mario characters in his videos. Because of this, the Mario characters were replaced by the human puppets introduced in 2019, and the channel is simply known as SML now. On July 8 of the same year, the original Super Mario Logan channel was officially deleted, along with 13 years' worth of videos. However, many fans have put in the effort to archive the channel, and most videos have been reuploaded, with efforts to locate the last few missing ones underway.

This series provides examples of:

    open/close all folders 

  • Abusive Parents: By the truckloads.
    • Bowser is usually a terrible parent to Junior. One example would be when, after learning that Junior is failing all of his classes, Bowser beats him with a belt and refuses to help him, instead getting Chef Pee Pee to tutor his son despite Chef Pee Pee having no expertise in the matter. Naturally, this leads to Junior cheating on his test and failing his semester, after which Bowser beats him with an extension cord. Oddly, though, Bowser seems to alternate between being kind to his son and being a negligent and abusive layabout.
    • Charleyyy once threw his infant daughter down a staircase.
    • In the "Bowser Junior's Playtime" videos, Junior plays a man named "Junior" (his wife played by Joseph and his daughter played by Cody), and "Junior" is an abusive workaholic who apparently sleeps with his secretary, calls his wife a whore, and beats his wife and daughter, constantly berating the both of them.
    • Downplayed with Mario. After he became the Parental Substitute to Jeffy, he tried to get rid of him in "Jeffy's Special Easter!" and "Where's Jeffy?", shot him with a Nerf gun saying, "Die Jeffy!", in "Bowser Junior's Nerf War!", locked him in the bathroom and pretended not to hear him in "Jeffy's Cellphone!", and tried to kill Jeffy with the help of the Loan Dolphin in "The Hitman!". Though otherwise, he doesn't physically or emotionally abuse Jeffy anyway outside of those examples.
    • Jeffy's mother Nancy, to the point the poor child is afraid of her. In fact, the only reason she came back for him is so she can get rich, as Jeffy's father Jacques Pierre François left all of his money to Jeffy following his suicide, which Jeffy can legally get once he turns 18.
    • In "Joseph's Mom!", it is revealed that Joseph's mom was alive the whole time, and she renounced her parenting for Joseph on October 31, 2015, after finding out that she won the lottery. She then bought a skeleton and a wig and put it on the couch, then left Joseph enough money to buy pizza before she left. Since then, she started a new life with a new family and husband, consequently rendering Joseph insane after he started believing that he killed his mom.
    • Barbara, Brooklyn Guy's mother, despises and verbally abuses her son for not spending time with her, even going as far as to insult his wife, while continuously praising her other son Jonathan... who happens to be a nerdy Manchild living in her basement and lusting over anime girl dolls and computers.
  • Accidental Art: In "Bowser Junior's Painting!", Junior accidentally drops his canvas onto his color plate in an attempt to make a $50 million painting. Joseph, Goodman and Cody redeem the result as beautiful.
  • Adults Are Useless: Pretty much every single adult figure there is ranges from ineffectual at best (Mario, Chef Pee Pee, Rosalina) to dangerously incompetent at worst (Mr. Goodman, Tyrone and Judy, Bowser), and it's even rarer that their attempts to have a presence in their childrens' life doesn't lead to some sort of disaster.
  • Affably Evil: Despite being, you know, the Devil, Craig is an extremely nice guy.
  • Afraid of Needles: Junior, as revealed when he had to get a flu shot.
  • Alliterative Title: "Cool Cody!" has an alliterative title.
  • All Just a Dream:
  • Alternate Continuity: It is implied that the "Human Puppet Era" takes place in one of these.
  • Alternate Universe:
    • Shrek is addicted to cheesecake, talks about taking a crap a lot, and calls everyone Donkey.
    • Woody is addicted to beer, shrimp-o's (He even has his own series) and NASCAR.
    • Bowser doesn't particularly care about capturing the Princess, lives in a suburban home, and watches Charleyyy and Friends constantly.
    • Bowser Junior usually plays with a Thomas toy, and his intelligence takes a massive nosedive compared to his cunning canon counterpart.
    • Black Yoshi wears a necklace and spends his spare time playing Call of Duty.
    • Sonic the Hedgehog has a British Accent and is often mistaken for a cat.
    • Chris the Cucumber is obviously Larry the Cucumber. Unlike Larry, whose only character trait is not giving tips/advice, all Chris does is give tips/advice, albeit always wrong tips/advice. He does give a few correct tips hilarious details.
    • Craig the Devil apparently owns Hell.
    • Windwaker Link is known as "Pixie Goblin", and was made in a kitchen by Chef PeePee by order of Bowser to make a new son.
    • Rosalina absolutely loses it and goes into total sobbing fits when she can't see the stars. She cries constantly about Luma being missing, and blames the sun, which she believes is a planet. This was only in her first two appearancesnote , though, as she became more of a stereotypical ditzy blonde afterwards.
    • Every single one of the Koopa Kids has a bizarre personality. They originally had fake names and there were six of them, all Bowser's kids from his ex-wife Sheila Perkins, however the remake retains their canon names and makes them the result of a cloning box that Junior bought from a homeless man and a drug-addicted clown.
      • Wendy seems to constantly correct Junior saying that he doesn't have 7 brothers and sisters, but just 1 sister and 6 brothers (which she screams).
      • Ludwig Von Koopa only knows how to say "Butt" and his own name.
      • Iggy Koopa is very shaky, and hyperactive.
      • Roy Koopa talks a lot like Birdo.
      • Larry Koopa seems to be unable to not stop saying his name repeatedly.
      • Morton Koopa Jr. repeatedly says he's a "watchdog"/"rockstar".
      • Lemmy Koopa admires Junior's toys.
    • Counterparts to existing Mario enemies and allies exist as well.
      • Cody is a Magikoopa who looks a lot like Kamek. He has a large number of medical disorders, and likes school a lot. He is also still breastfed by his mother who makes him sleep in the same room, appears to be a closet homosexual, and believes his Ken doll is real.
      • Toad is a massive idiot who runs on absolute Insane Troll Logic and happens to be a serious Chubby Chaser. And he is a rapper, too.
      • Toadette appears twice. Supposedly there are two, one who is Toad's sister (of whom Toad and Junior are romantically interested in) and she speaks with a masculine Brooklyn accent, another who has a higher pitch accent and isn't related to Toad, but looks identical to the other Toadette.
      • Joseph, his friend from school is a Koopa Troopa who likes to play sports and wears braces. He idolizes Kobe Bryant and other famous basketball players. And yes, according to his American Idol audition, his last name is "His Friend from School".
      • A Shy Guy appears named Tanner who believes he's a super cool dude, likes to bully others, but when he gets bullied he argues that people can't bully him because he has home life problems so it's wrong to do so.
      • A Goomba appears on and off who repeatedly states he has no arms so he can't do certain tasks.
    • A Princess Zelda appears briefly in Bowser Junior's first grade, and describes herself as spoiled and not wanting to go to school.
    • Mickey Mouse is a greedy jerkass who is a drug addict and drug dealer.
    • Mario accidentally enters a literal alternate universe in the first Season 3 episode of Mario and Luigi's Stupid and Dumb Adventures, where there are counterparts to most of the actual SML characters:
      • Bowser is working for Chef Pee Pee, who himself watches Harleyyy and Friends insted of Charleyyy and Friends.
      • Shrek is obsessed with sweet peas and taking pees, and calls everyone "Camel".
      • A white Yoshi is in Black Yoshi's place, and he plays Animal Crossing on the Wii instead of Call of Duty, the latter of which he considers too violent.
      • Toad is a country singer, and his voice is deep, compared to his actual high voice.
      • Mama Luigi is intelligent and very smart, compared to his retarded personality in the actual SML universe. He also claims the alternate Mario to run around the house making unintelligent noises, very much like the actual Mama Luigi.
      • There is no counterpart to Bowser Junior, Woody, Tony the Tiger or any of the recurring characters.
  • Always a Bigger Fish:
    • If you thought Junior was a brat, JEFFY is even more so, crying for chocolate cake and locking Mario out of the house over it, and even INJURING himself to fake allergies just so he could eat cookies instead of healthier food. If you thought characters like Mama Luigi and Tony the Tiger were stupid, JEFFY manages to outdo all of them. If you thought Black Yoshi got Mario into embarrassment constantly, JEFFY somehow humiliates Mario on a global scale, and the media not only accepts his downright lies but also passes Mario off in the wrong.
    • If you thought Bowser was a horribly mean Abusive Parent, then you clearly haven't seen Nancy.
    • Speaking of which, Bowser's belt beatings are bad enough at first, until you realize that Chef Pee Pee could break a leg with his bare hands, as Junior found out the hard way at the end of "Bowser Junior's Broken Leg!".
    • Quoted word for word by Joseph in Chef Pee Pee's New Job!, as he recounts how he saw a mother about to beat her son only to be beaten by her husband instead.
  • American Accents:
    • Brooklyn T. Guy has a thick Brooklyn accent.
    • Toad's sister, Paulina, also has a Brooklyn accent.
    • Tanner and Joseph most likely have Californian surfer accents due to their usage of dudes.
  • Amusing Injuries:
    • Junior gets two black eyes and is thrown into a wheelchair from saying the N-word three times, as shown in "Bowser Junior's YouTube Channel!".
    • In "Jeffy's Homework!", Jeffy gives Mario a blackened face (and potentially even a brain hemorrhage) while playing teeball, just after Mario claims that it was safe to play in the first place.
  • Amateur Film-Making Plot: In "The Film Project!", Jackie Chu assigns his students to make short films for a film festival he is hosting at Y U Dumb? Elementary School, where the winner will receive an Oscar award. On the night of the award ceremony, the student's films are shown. Joseph's is "My Life Socks!", which shows a love affair between a sock puppet couple (with many sock-themed puns), Jeffy's is "Fruit Party 4", which depicts a bunch of fruit talking with Synchro-Vox a la The Annoying Orange, Penelope's film is of her fawning over Justin Timberlake in black and white (which is unfinished due to her father, Brooklyn T. Guy interfering), Cody's film is "TiKenic", a remake of Titanic (1997) starring him and his Ken doll, and Junior's is "Doomsday in Townsville!", where the City of Townsville is under attack by a T-Rex and a giant tarantula as a result of The Powerpuff Girls going on vacation. Cody slapping Junior over "Cody's mom is a pig" jokes in his movie, and then later winning the Oscar, is even a direct reference to Will Smith doing the same to Chris Rock at the 2022 Oscar Awards.
  • An Arm and a Leg:
    • In "Bowser Junior's Lightsaber!", Junior accidentally chops off Chef Pee Pee's arm with a lightsaber.
    • He also cuts off his own hand (and later Chef Pee Pee's) in "The Gun!" after getting in trouble from his and his friends' fingerprints ending up on the titular gun.
  • And I Must Scream: In "Bowser Junior's Annoying Toy!", Chef Pee Pee traps Junior inside a ball popper toy, after asking him to put in something "loud and annoying".
  • And You Were There: Lampshaded in "Bowser Junior Needs Glasses!":
    Bowser Junior: I just had the craziest dream! (starts pointing at everyone) And you were there! And you were there! And you! And you!
  • Annoyingly Repetitive Child: Jeffy (who was twelve at the start of the series) often says, "Why?" in response to any of Mario's orders, much to the latter's chagrin.
  • April Fools' Plot:
    • "April Fools!" is based on this. Turns out it was actually April 2nd.
    • "The Funeral!" has Barbara seemingly dying of a heart attack. Jonathan is reduced to a sobbing mess, while Brooklyn Guy is more than happy to no longer deal with his abusive mom, despite his wife forcing him to go to the titular funeral....until Barbara later shows up alive at his house and reveals she faked her death for April Fools' Day. Brooklyn even calls her a psychopath for deciding to pull such a prank on her family.
  • Arc Words: "Bowser Junior's Cookies!" has...well, "cookies". At the end of the video, the trope is repeated again, this time with "Chips Ahoy cookies".
  • Arson, Murder, and Jaywalking: In Part 7 of "Luigi's Mansion," Craig says that jaywalking will usually get you into Hell (and that not tipping the mailman is nearly as bad). In "Evil Chef Pee Pee!", he declares to send Chef Pee Pee to hell due to the latter "jaywalking pretty bad back in 1997", and he even makes Junior pay for a Hershey's candy bar at a convenience store entirely with pennies.
  • Artistic License – Biology: In "Bowser Junior's Playtime 3", Sally (Cody) is revealed to be pregnant with Ken's child. In the next part after her wedding with Ken, she gives birth to Phoebe. The amount of time that passed between the two parts is not stated, but it's implied to be way less than the nine months it should take for a baby to develop since in part 3, Junior and Joseph decided to get a divorce and the divorce gets finalized in part 4, which shouldn't have taken that long to happen. Justified since Junior, Joseph, and Cody are just kids and probably don't know everything about pregnancy.
  • Artistic License – Education:
    • In "Bowser Junior's Homework", Junior has to study for an exam and, apart from the spelling, he also has to study calculus and Chinese. He was in Kindergarten during this video, so it would be too difficult for him. This is Lampshaded by Chef Pee Pee, who says that he should only be doing the spelling.
    • Jackie Chu is a huge offender. He teaches difficult subjects to his elementary-aged students, he insults them, calls them dumb (which he's got a point since he has people like Junior and Jeffy in his class), he is inappropriate, he uses Asian stereotypes, and he once taught his second grade class how babies are made. The students think he's a Cool Teacher, nonetheless.
    • In the "Bowser Junior's 1st Grade" series, Junior's teacher, Mr. Winkle, is arrested when it's revealed that he's a pedophile. At the parent-teacher conference, Principal Steinbeck and Officer Goodman state that they had done a background check on Winkle, which he failed, but they ended up hiring him anyway because he called them both hot. They realize at this point that they were duped. The parents are not pleased.
  • Artistic License – History: In "Bowser Junior's Clown Car!", one of Bowser's high-school memories from 1985 is a Barney the Dinosaur doll. In real life, Barney didn't exist at that time, and wasn't even a thing until October 1988.
  • Art Shift: "The Warp Pipe" uses 16-bit sprites for the pipe dimension, including sprites ripped from Super Mario World and Super Mario Maker, as well as custom 8-bit sprites of Chef Pee Pee and Brooklyn T. Guy.
    • In more recent videos, whenever Brooklyn T. Guy tells a story, it turns into 2D animation by Nicktendo.
  • Ascended Extra: Junior once appeared in an early episode of Mario and Luigi's Stupid and Dumb Adventures, and didn't appear again until the Bowser Juice commercial. He then reappeared in "Bowser Junior's Macaroni", and slowly ascended into a main character afterwards.
    • Brooklyn T. Guy, as well. He made his SML debut in a 2011 SML Short, and was Put on a Bus following the video. He then returned at the end of "Bowser Junior's Summer School 5", and is now a recurring character with so far over 30 jobs.
    • Joseph and Cody went from appearing only in the Summer School series to appearing in half of Junior's appearances in late 2014 and 2015 to appearing in every single one of Junior's 2016 appearances, excluding "Bowser Junior's Cookies!", "Bowser's Goldfish!", "Bowser Junior Learns Karate!", "Smart Jeffy" and "Jeffy Loses His Teeth!", among a few others.
    • JEFFY. After going through a Chuck Cunningham Syndrome period following his debut, he reappeared in "Bowser Junior's Game Night 3" and slowly ascended to main character position (and arguably the channel's de facto mascot), very much like Junior did.
  • Ashes to Crashes:
    • At the end of "Cody's Revenge!", Junior accidentally knocks over the ashes of Bowser's pet cat, which prompts him to send his son to military school.
    • In "Jeffy Gets Framed!", Junior breaks a vase containing Rosalina's grandparents' ashes while playing with his friends, and alongside Joseph and Cody blames Jeffy for the accident to get out of trouble.
  • Asians Eat Pets: Jackie Chu frequently mentions eating dog for dinner. In one video, he even laments about how expensive it is to buy dogs from the pet store for dinner everyday.
  • Asian Speekee Engrish: Jackie Chu.
  • Ass Shove:
    • In "Cody the Magician!", Junior does this with Cody's 6 of Clubs card after Cody tells him to do it.
    • In "Jeffy's Birthday!", Jeffy does this with the giant pencil Mario gets him as a birthday present.
  • Attention Deficit... Ooh, Shiny!: After Junior gets his own credit card (which is very unuseful for his age), he tries his best not to spend it but winds up distracted by several TV advertisements. It gets worse when Joseph later starts suggesting him more expensive things such as a trampoline, a swimming pool, ten pizzas and a bounce-house, that Junior delicately accepts despite Cody's warnings, eventually going beyond his $10,000 limit and therefore getting into hot water with the Loan Dolphin and Mr. Goodman, because he never paid the money back for all the things he spent his credit card on.
    • In "Bowser's Cookies", Toad gets distracted by a running cat, leaving the cookies that he's watching over to burn in the oven.
    • The plot of "Bowser Junior's Candy Bar!" gets kicked off because of Junior's attention span; he ends up stealing a Hershey's chocolate bar despite warning himself to not want anything. It eventually turns out that Screwball was the one who stole the candy from the gas station, and Chef Pee Pee noticed that Junior was taking a chocolate bar earlier and made sure that he paid for it.
  • Author Avatar: A puppet version of Logan appears in "Bowser Junior's 1st Grade! Part 4".
    • In "Jeffy & Junior's Gold Play Button!", Logan, along with the other male cast members have new puppets.
    • Those very same puppets introduced in that video eventually get a video for themselves in the form of "Jeffy Loses His Voice!".
  • Ax-Crazy:
  • Babysitting Episode:
    • In "Black Yoshi's Job", Bowser and Chef Pee Pee have to go to the hospital after the former thinks he has chicken pox (thanks to Charleyyy) and the latter accidentally chops his own hand off after hearing a yell from the former, and they need someone to watch Bowser Junior. Since Black Yoshi needs the money to buy the Call of Duty: Advanced Warfare game, Mario volunteers him to babysit Junior. Junior soon finds out he's no match for Black Yoshi, as Black Yoshi shoots his toys whenever he acts like a Bratty Half-Pint, and even shoots Toad when they play doctor together.
    • Black Yoshi gets another babysitting job from Mario in "Jeffy's Mistake!", when Mario asks him to babysit Jeffy while he takes Rosalina out on a date. To keep Jeffy entertained, Black Yoshi lets him play a game of Grand Theft Auto, which results in Jeffy destroying his Xbox One. Needless to say, Black Yoshi does not take this well.
    • Shrek gets a babysitting job from Mario in "Shrek the Babysitter!", wherein he has to babysit both Bowser Junior and Jeffy when Bowser and Chef Pee Pee go to a gay strip club, and Mario has to take Black Yoshi to his probation meeting. As a prank, Junior and Jeffy lock Shrek in the bathroom. They later eat his cheesecake, which turns out to be a big mistake when Shrek breaks out.
    • Chef Pee Pee gets a babysitting job from Mario in "Chef Pee Pee The Babysitter!", when he asks him to babysit Jeffy while he goes to a meeting at Nintendo headquarters, promising to pay him $500 when he gets back. Chef Pee Pee has to juggle both looking after a disruptive Jeffy and cooking everything Bowser wants to eat, especially since Bowser also promised to pay him $500 if he succeeded.
    • In ''Bowser Junior the Babysitter!", Junior babysits Mr. Goodman's infant son, Benjamin Franklin Goodman, so that he can earn $800,000.00 to donate to Tom Brady and have dinner with him (a dare given to him by Jeffy in Truth or Dare). When Junior leaves Benjamin alone to play video games, Chef Pee Pee decides to prank Junior into thinking that Benjamin has gone missing to teach him a lesson in responsibility.
  • Bedsheet Ghost: In "Bowser's Change!", Junior steals $100.00 from Chef Pee Pee that Bowser gave him to buy a pizza with so that he could buy Animal Crossing: New Horizons, only for to Joseph spend the money on candy and a lottery ticket (which he lost on). After Junior tricks Tyrone into giving him into the pizza for free, Chef Pee Pee forces him to explain to Bowser why he doesn't have the change he was expecting, so he lies to him that he tipped the pizza guy $80.00 because he was a ghost and didn't want him to spook them. When Bowser wants to see the ghost as proof, Junior disguises himself as a ghost using his Thomas & Friends bedsheet. Bowser still falls for Junior's trick despite the fact that the characters from Thomas are clearly visible on the bedsheet, but Junior's ruse is exposed when Bowser tries to give him a hug.
  • Berserk Button:
    • NEVER mess with Black Yoshi's Call of Duty or ask him to play 2 Player. And if you know what's good for you, you won't destroy his Xbox One.
    • Don't eat Shrek's cheesecake. You'll be sure to have a bad death.
    • If you're playing trains with Junior, don't ever play with Thomas, even if he has more than one, as he always wants to be Thomas. He'll make you play with another train, most commonly The Ugly Red Onenote . Also, don't ever say anything positive about Big Hero 6 around him.
      • Don't ever, ever think of stealing Junior's stuff. He will kill you, or at least beat you up.
    • Bowser hates it when people call him while he's watching Charleyyy and Friends.
    • One thing that irritates Cody the most is Junior telling him the Sun is a planet. This has gotten so bad that Cody actually shoved Junior down a set of stairs when he said it.
    • Never EVER cheat on Rosalina, she will give you a beating if you're looking at another woman behind her back. Never mind that she has half a dozen ex-boyfriends which whom she’s very fond with.
    • Jeffy's obnoxious behavior is a big button for Mario.
    • Don't ever call Tyrone Calvin by the N-word or by the F-word (the OTHER F-word). You'll be sure to suffer Amusing Injuries, as Junior and Mario found out the hard way in "Bowser Junior's YouTube Channel!" and "Jeffy's Bad Word!", respectively.
    • In "Jeffy Loses His Teeth", it is shown if you give dollars to Jeffy if he loses his teeth, he will not take it well.
    • Do not call Jeffy "bad" and never give him green beans.
    • Do not ever destroy Cody's Ken doll. Cody will surely take it HARD.
    • Take or scam Goodman out of his money, and you will be sorry. Jeffy and Black Yoshi learned this the hard way in "Invisible Jeffy!" and "Black Yoshi's Big Bamboozle!" respectively.
  • Big Bad:
    • Nancy from "Jeffy's Parents!".
    • Does Bad Things Guy from "The Secret Door!".
    • Principal Steinbeck from the Bowser Junior's Summer School series.
    • Mr. Winkle for Parts 2, 3 and 5 of Bowser Junior's 1st Grade!.
    • Bowser, one of the main characters on the channel, was originally a villain, but thanks to Villain Decay he eventually ends up becoming an anti-hero.
  • The Bet:
    • The appropriately-titled "The Bet!" has Mr. Goodman entering the "Best Chef" competition against Chef Pee Pee and betting all his money on himself to win on Mario's suggestionnote  Surprisingly, Chef Pee Pee wins and Goodman is left as broke as a joke, forcing him to work as Bowser's temporary chef for a while. It turns out the Loan Dolphin jumped judge Brooklyn T. Guy and mugged him out of his phone to coerce him into choosing Chef Pee Pee.
    • "The Contract!" has Goodman entrust Marvin with a big contract that could change his life, and all he needs to do is talk out with his family for ten minutes. What Marvin doesn't know is that Goodman organized a bet with fellow rich friend Greg to see if he would destroy within the exact timeframe, given Marvin's track record in looking after Goodman's stuff. After winning the first time, Goodman gets cocky and goes for double or nothingnote , then triple or nothing note , and consequently loses all the money he earned when Marvin actually does keep the second copy of the fake contract safe.
  • Big Damn Movie: Logan was revealed to be working on one.
  • Big "NO!": Harry uses this as his catchphrase in style of Montone/British
    • Junior does one in "Hunky Cody!" when he realizes that he's not hunky.
    • Bowser screams one in "Bowser's Mistake" After sending another horrible pic to his mother.
    • Jeffy yells this after seeing Beary Die.
    • Black Yoshi screams twice, after learning that Call of Duty: Infinite Warfare is sold out ebcause of Bowser Jr. getting the last copy.
    • Cody screams in "Mistaken" after hearing that Ken is in the moon.
  • Birthday Episode:
    • Bowser Junior has had five; "Bowser Junior's Birthday Cake", "Bowser Junior's 6th Birthday", "Bowser Junior's 7th Birthday!", and "Bowser Junior's 8th Birthday!", and "Bowser Junior's 9th Birthday!".
    • In "Chef Pee Pee's Birthday", Chef Pee Pee has a crappy birthday thanks to Bowser, Junior, and his deadbeat father. In particular, Bowser gave him a spatula, Junior gave him The Ugly Red Train (and later took it back), and his father was happy he didn't have to pay him any child support. Jackie Chu later turns things around for him by giving him a shirt with his name on it and informing him he will also be getting an iPad in the mail. Jackie Chu also invites Chef Pee Pee to help him name his pregnant wife's upcoming child.
    • Chef Pee Pee celebrates his birthday again in "Chef Pee Pee's Birthday Surprise!". When Junior overhears how upset Chef Pee Pee is (due to having to clean up both Chompy's poop and Junior's pee), he decides to throw him a Thomas & Friends-themed party with the help of his friends. To keep it a surprise, he locks Chef Pee Pee in his closet. To say the least, Chef Pee Pee goes through an emotional rollercoaster at his party.
    • "Chef Poo Poo's Kitchen Disaster!" takes place during Bowser's Mom's 200th birthday.
    • "Cody's Birthday!" has Cody revealing his birthday is on February 29th, which falls once every four years, and telling Junior and Joseph that he's 8 years old, but technically actually two years old because he was born on a leap day. Hearing this, Junior and Joseph start making fun of him over his age, to the point where they even make a baby-themed birthday party for him and pretend that he's a baby himself.
    • Jeffy celebrates his 12th birthday in "Jeffy's Birthday!", wherein he wants to go to Disney World to see Mickey Mouse. Because Mario doesn't have the money to go to Disney World, he decides to spend Jeffy's birthday at Chuck E. Cheese's, seeing as they also have a mouse for a mascot, hoping Jeffy won't know the difference. He also gets Chef Pee Pee to make a pencil cake for Jeffy and invite Junior, Joseph, and Cody.
    • Jeffy celebrates his 13th birthday in "Jeffy's Birthday Wish!", which happens on the same day as the American solar eclipse. Jeffy makes a wish that his birthday would last forever, which causes the solar eclipse to get stuck. It is also revealed in that episode that Hansel the Hobo and Brooklyn T. Guy also have the same birthday as Jeffy.
  • Black Comedy: The show mostly has upbeat humor, however many scenes and offbeat jokes in the show are this trope.
    • Nearly any scene involving Bowser have him beating the hell out of his son while his son screams in pain until Bowser calms down. Granted, Junior usually starts it.
    • The episode "Bowser Junior's Punishment!" has Junior reacting to being in the corner for five minutes akin to a man who's been in solitary prison for a decade.
    • One Charleyyy and Friends episode is about Charleyyy daring to eat an onion without crying, only for him to breakdown about his dad leaving him as a child. Bowser laughs.
      • In another during the Luigi's Mansion arc, Charleyyy dances in the street recklessly and gets hit by a car. Bowser notes he's even funnier when dead.
      • In yet another, Charleyyy notes it is Mother's Day and he's with his beautiful baby daughter. He then switches to a deadpan speech as he admits his daughter doesn't have a mother because she left, and then hurls his daughter down the stairs, with Bowser laughing at how hilarious it is. It's just a baby doll, but still.
    • Doofy the Dragon is a kid's show involving Doofy singing about drugs, testicles, and killing. He always kills himself at the end of each episode, and Bowser Junior laughs.
    Doofy: (singing)
    Twinkle, twinkle, little star
    I have drugs inside my car
    If the cops show up I'm (BLEEP)
    I might as well give myself up.
    (cue police siren) Oh (BLEEP), it's the cops, I better run
    I'm gonna kill myself with this gun. (shoots self)
    Junior: (laughs) That's so funny, Doofy!
    • From Bowser's Video Game.
      Charleyyy i wish my dad can touch me when i was little.
    • "Home Alone" has Junior killing one of three criminals by dropping a bowling ball on her, and putting one of them in the oven, after both of which he electrocutes the last one unconscious and ties him to the tracks with the intent to cut his head off. Officer Goodman arrives in time, though, and arrests the last criminal before being executed. Junior is not charged, however. What makes this even darker is that when the first criminal dies, both of the remaining ones note that the first one just recently had a kid and didn't even want to be here, and the second criminal who dies steals Junior's Thomas the Tank Engine toy because his son has always wanted one.
    • Black Yoshi spends most of his episodes committing jokes like this. He kills Joseph ("CharleyBrown678") for cutting his electricity, and shoots Junior's toys when he acts like a brat.
    • In the Who Wants to Be a Millionaire? spinoff, two of the questions are:
      • 1. How many planes were hijacked on 9/11? A. 2. B. 4. C 7. D. 45.
      • 1. How many people died in the Holocaust? A. 11 Million. B. 6 Million. C. 17 Trillion. D. 12.
      • The Brooklyn Guy notes how ridiculous these answers are, especially mad at the question writer for putting "12" as a logical possible answer to the number of people who died in the Holocaust.
    Brooklyn Guy: How many— (sees question and sighs) How, wow, already. Okay, how many planes were hijacked during the September 11th Terrorist Attacks. A. Two. B. Four. C. Seven. D. Forty-forty-five. Forty-five. Really? Forty-five planes? That's a lot of planes. How many-how-how would they get that many planes? They would crash into each other. Who wrote this? Let me write it next time. This is ridiculous. (looks at Craig the Devil) It's not that one. I'll tell you right now it's not that one.
    Brooklyn Guy: How many people- man, these questions are sad. Okay, how many died during the Holocaust? A. Eleven million. B. Six million. C. Seventeen trillion, that seems kinda high. And D. Twelve. Twelve people. Twelve-yes-twelve people died in the Holocaust. Twelve. There's-there's more people in the audience tonight than died in the Holocaust. Yeah sure, yeah that makes sense. Yeah okay, twelve people. Twelve peo-Twelve people would even be that big of a deal. Twelve people would be-it would barely make the paper, maybe a local paper, like, in a small box on the bottom. But-but that's pretty much it. Ugh. (whispers) Goddammit. (speaks loudly) Who is writing these? Who is-who is actually writing these? Is it Kevin? I bet it's Kevin that stupid bastard. I bet it's him, I bet money it's him. That's coming out of your paycheck if he gets this right. It is. Yeah, you.
    • In Bowser Junior's 1st Grade!, one of the class's teachers is a pedophile who is implied to have molested Cody in the bathroom during lunch.
    • Bubbles is a convicted serial rapist. When he appears in the Summer School arc, he escapes his cuffs, runs away, then runs back to the classroom and grabs Pixie Goblin before running again. When Pixie Goblin shows up again, he says he doesn't want to talk about what happened and sobs. Later, in the same episode, it's show and tell, and during Pixie Goblin's show and tell he tries to show his sword. Officer Goodman mistakes it for a real weapon and doesn't realize it's sewn to his hand, resulting in Pixie Goblin being reunited with Bubbles.
    Bubbles: (grabs Pixie Goblin with a crazed smile) Ready for round two?!
    • Chef PeePee calls the number for the Crocodile Hunter, only to be informed that Steve Irwin died due to a stingray attack. He notes that weird because he wasn't the "Stingray Hunter". In reality, Steve Irwin is the name of a man known as the Crocodile Hunter who did die from a stingray attack.
    • Craig the Devil notes his dogs are barking, unlike Michael Vick's.
      • Mario also notes Vick in "Jeffy's Dog!".
    • During "Bowser Junior's Clown Car!", Bowser and Junior are looking at Bowser's old yearbook from high school. Bowser is shown in the yearbook with a red afro and mustache, and Junior notes he looks like he was about to shoot up a movie theatre in Colorado. Bowser simply admits he was going to but didn't get around to it. The red afro and shooting joke are a reference to the 2012 Aurora shooting by James Holmes, who had dyed his hair red prior to the shooting and had it in an afro.
    • The Bowser Junior's Playtime videos and the Thanksgiving Playtime Special shown in the 2014 Thanksgiving Episode.
      • Junior is an alcoholic who beats his wife, berates his daughter and wife, tried to abort his daughter's pregnancy by attacking her, didn't care when his wife was cooking his daughter, sleeps with his secretary, and even tried to kill his granddaughter because he didn't like her name.
      • Joseph plays the wife who regularly argues, screams, and cries with the anger directed at Junior. She is apparently sleeping with a Hispanic man, and even admits to not wanting her own daughter.
      • Cody plays "Sally" the daughter who is in love with a man named "Ken" who got her prematurely pregnant. She apparently still wears diapers at her age, and is forced to witness her parents' constant bickering and yelling. She has also been told by both of them that neither actually love her. It's a good thing this is Pretend House.
  • Blanket Fort: The whole point of "Bowser Junior's Pillow Fort!". Junior builds his own pillow fort, which he names "Fort Junior", and when he invites his friends in they are cramped inside thanks to Cody and Ken. This gets Junior to forbid Ken from entering the fort, which in turn prevents Cody from going in as well. This results in Cody building his own fort and inviting Joseph in. In the end, both Junior and Cody destroy each other's pillow fort, and an angry Chef Pee Pee blames the resulting mess on Junior and forces him to clean it up.
  • Blatant Lies: At the end of "Drawing Jeffy!", Junior captures Drawing!Jeffy in a piece of paper and crumbles it up while saying that he's never coming back to life ever again. Come June 15th 2017, only a month later when "Jeffy Sneaks Out!" was uploaded, which involved Jeffy bringing back an identical form of Drawing!Jeffy from PlayDoh in order for him to serve as a substitute for Jeffy while he and Junior go out to see a movie.
  • Blonde, Brunette, Redhead: Out of the six main kids: Junior and Penelope are the redheads, Joseph, Cody, and Jeffy are the brunettes, and Timmy is the blonde.
  • Bloody Hilarious: Some episodes like "The Drone!" and "The Gun!" have a fair amount of Played for Laughs Gorn.
  • Book Ends: "Where's Jeffy?" begins and ends with Jeffy riding a unicorn piñata while playing a maraca, a rubber chicken, and a cat piano, while Mario plugs his ears.
  • Bottle Episode: "Shrek's Hot Cheesecake" from 2013, which only has two characters (Shrek and Woody), both of which are voiced by only one voice actor (Lance), and is mostly set in the kitchen.
    • "Jeffy's Fun Day!" is arguably also this, as it's mostly a literal hour of Jeffy watching paint dry.
  • Bowling for Ratings:
    • In "Bowser Junior Goes Bowling!", Junior, Joseph, Cody, and Toad get Chef Pee Pee to take them to the Wacky DeLuna Bowling Lane after seeing a commercial for it on television. Cody turns out to be an expert at bowling despite never having played it before (and scores a perfect game by the end of the video), while Joseph quits after one turn. Chef Pee Pee struggles to get a strike, and has to make a deal with Craig the Devil just to get one.
    • In "Jeffy Goes Bowling!", Mario plans to take Rosalina to the bowling alley for a tournament to win $5,000.00 after seeing a commercial for it on TV. When Jeffy breaks Rosalina's arm, Mario takes Jeffy to the bowling alley, where they compete against Brooklyn T. Guy and his wife, Karen. Mario discovers that Jeffy can make perfect strikes blindfolded, while Brooklyn tries to cheat by hiring a guy behind the pins to knock them over with a broom whenever Karen bowls. The game ends in a tie, meaning that neither team wins the money.
  • Box-and-Stick Trap:
    • In "Bowser Junior Gets Rabies!", when Chef Pee Pee discovers Junior has rabies, he calls Brooklyn T. Guy for a solution on how to cure him. Brooklyn suggests capturing Junior using one of these traps before he shows up as a doctor. Chef Pee Pee does so, using Junior's golden Thomas the Tank Engine toy as bait. When Brooklyn shows up later, he asks Chef Pee Pee if he recorded Junior's capture in the trap for him to see, but Chef Pee Pee tells him he didn't.
    • In "Cody Gets Expelled!", when Junior, Joseph, and Cody make evil clones of themselves, Junior builds three of these to catch them. The bait Junior uses are his Thomas toy for his clone, Cody's Ken doll for Cody's clone, and a $5.00 bill for Joseph's clone.
  • Breaking the Fourth Wall: The show obviously loves this trope.
    • When Joseph, Junior, and Cody are going to get their pictures taken by Mr. Winkle:
    Joseph: I don't like showing my braces off.
    Junior: You have braces?
    Joseph: Well, see?! There you go!
    Cody: Joseph, we don't even have mouths.
    • When Chef PeePee is getting frisked for being "brown" in "Chef Pee Pee Quits! Part 1":
    Goodman: What is this? What is this?!
    PeePee: It's the hand that's controlling me right now.
    • In "Bowser's Broken TV", Chef Pee Pee turns to the camera at one point and says "I'm-a be here all week, people".
    • In "Black Yoshi's Fried Chicken", after Tyreese kills Chef Pee Pee, and he and Black Yoshi cook him into fried chicken and eat him, Mario is outraged and disgusted with them.
    Mario: So many fans are going to think that he's not gonna be in the next video, but he really is!
    • From "Evil Bowser":
    Mario: Bowser, you're... you're just not evil anymore. I mean, people used to look at you as this big, evil, scary monster who did bad things, but people just look at you as a old, lazy, bipolar white guy.
    Bowser: (gasps) But I'm black! I'm voiced by a black guy!
    Mario: Y-you're voiced by a black guy?
    Bowser: You know what? Never mind!
    • From "The Warp Pipe!":
    Mario: I'm just not doing it any more! I'm stick and tired of the stairs!
    Chef Pee Pee: Well, I have to climb up and down every day to take Junior to school, and get Happy Meals! So you're not the only one who has to deal with it!
    Mario: (looks down at Chef Pee Pee) Well, I mean, you don't... you don't have legs. You're...
    Chef Pee Pee: Wait, don't worry about my legs!
    • From "Bowser Junior's Halloween Problem!", when Bowser Junior is trying to relax:
    Junior: What's stuff that's not scary? Uh...uh, YouTube comments! Yeah! Gonna think about YouTube comments. (four comments appear on screen saying they hate Junior)
    • In "Cool Cody!", Junior does it twice. At one point, he tells the audience that the Toadette appearing in the video isn't the same one from the previous video (likely referring to "Toad's Girlfriend!") and that there are different Toads and Toadettes in the Mario Universe. Later on, he mentions that he and Joseph had Ken in one scene when they couldn't find him in the previous one.
    • "From "Bowser Junior's Clown Car!":
    Junior: Okay, there's something on top of the refrigerator, and I need yall's help to get it 'cause I'm too short.
    Joseph: Okay.
    Cody: Junior, we're... we're controlled by hands. I mean, look, I... See? We can go as high as we need to.
    Junior: Stop breaking the fourth wall, Cody!
    Joseph: Yeah, Cody! Always ruining stuff!
    Cody: Sorry.
    • In 'Bowser Junior's YouTube Channel!", Junior uploads a prank video where he clearly paid off the prank victim. Two comments are left on the video, one of which says "fake and gay", and posted by a certain YouTuber. Junior looks at the name and yells, "Well, screw you SuperMarioLogan!"
    • In "Pop Rocks and Coke!", Junior mentions cutting to the next scene and therefore getting packets of Pop Rocks and a can of Coke in the process.
    • From "The Tarantula!", when Chef Pee Pee tries to convince Junior to get a new pet after Chompy runs away:
    Chef Pee Pee: Look, look, look, this is your chance to get a new pet. Why don't you just get a cat or a fish, or...
    Junior: There was, there was a cat in an earlier scene if you look in the background. (referring to Logan's own cat Precious)
    Chef Pee Pee: Oh, yeah.
    • In "Bowser Junior's Game Night 4", when Junior, Joseph, and Cody play Jenga Quake, Cody mentions that he saw some comments informing him that after you take a block out, you have to put it on top of the tower, which is what they forgot to do last time they played Jenga.
    • The entirety of the ending sequence of "Evil Chef Pee Pee!" is a huge joke with this trope. Junior admits they didn't really think the ending through, and Cody tells them to get to the SML Question (the question Logan always asks at the end of every video). The question has Cody being incredibly sarcastic enough to ask, "Have you ever thrown a frozen water balloon at your personal chef and accidentally killed him. And then summon the devil to bring him back but then he came back evil and killed your dad and a cop?" Junior says that's a brilliant question and the funniest comment will win a free video game. He then also goes on to mock everyone who complains about not getting their game, as he says that maybe everyone should be checking their YouTube messages as a clip of Logan checking his YouTube message inbox plays.
  • Breath-Holding Brat: In the episode "Jeffy's Tantrum" (before it was taken down), one of Jeffy's tactics of getting Mario to purchase a $2.99 game for his iPad was to hold his breath until he dies.
  • Brick Joke:
    • In "Chef Pee Pee's Clone", after Chef Pee Pee gets out of the bathroom, he says, "I took an opposite of a Chef Pee Pee in there! They should call me Chef Poo Poo!". Guess what Junior names Chef Pee Pee's clone at the end of the video.
    • "Bowser Junior Loses Thomas!" begins with Junior playing with Thomas and a dinosaur toy. At the end of the video, when Chef Pee Pee finds Thomas and gives him back to Junior, Junior loses his dinosaur toy and calls for Chef Pee Pee to help him find it.
    • In "Black Yoshi's Girlfriend Problem!", after Delilah breaks up with Black Yoshi, she hooks up with Popeye, who tries to open up a can of spinach so he can beat up Black Yoshi. Unfortunately, he can't get the can open. At the end of the episode, Popeye returns, revealing he finally got the can open.
    • In "Cody the Magician!", Junior shoves the 6 of Clubs card up his butt. Later in the episode, when Cody's Ken doll does his escape artist trick, the card that was previously in Junior's butt appears in the tank, in Ken's place, complete with some noticeable stains.
    • In "Jeffy's Mistake!", Black Yoshi gets triggered after Jeffy destroys his Xbox One. At the end of the video, after Mario wakes up and realizes the entire video was just a dream, he also gets triggered when Jeffy tells him he pooped in Mario's bed.
    • At the beginning of "Big Ears!", Chef Pee Pee tries to cook a pizza, only to find Junior's G.I. Joe action figures in the oven. At the end of the episode, when Chef Pee Pee takes the pizza out of the oven, pieces of Junior's G.I. Joe action figures can be seen in it.
    • In "The Fortune Cookies!", Junior accidentally knocks Joseph on the head when he brings the ordered fortune cookies. Near the end of the video, Junior and Cody notice that Joseph has been unconscious and wake him up, with him complaining about having a headache.
  • Bring My Brown Pants: Junior in Chompy's body in "Life Is Ruff!" after Chef Pee Pee yells at him.
  • Broken Record: Stephen Hawking in Smart Jeffy, when his voice glitches out, causing him to get eliminated.
  • Butt-Monkey:
  • The Cameo:
    • Both Peach and Junior qualify as this in "Mario's Beautiful Date!".
    • "Bowser Junior's Nerf War!" has Jeffy and Mario of all people appearing at the end.
    • Logan's cat Precious makes three brief appearances in "Bowser's Cookies", "The Tarantula!" and "Bowser Junior's Bad Luck!".
  • Camping Episode: "Bowser Junior Goes Camping!"
  • Can't Get Away with Nuthin': Joseph tries to cheat on his exam, he gets busted. Junior tries to alter his grades on his report card, he gets busted. Junior tries to lie about breaking his dad's favorite cup, he gets busted. Junior tries to fix the table that he broke with Bowser's old Clown Car, he gets busted. Joseph tries to joke around by writing "Adolf Hitler" on his nametag, he gets busted.
  • Can't Live with Them, Can't Live without Them: Mario begins to show signs of this in "Jeffy's Mistake!" when Black Yoshi threatens to kill Jeffy and Mario tries to stop him claiming that he "really hates Jeffy but he's just a kid" and tells Black Yoshi not to kill him. He comes to his senses though after Black Yoshi asks him to buy him a new Xbox in trade of killing Jeffy.
  • Cassandra Truth: In "Chicken Pox!", Junior, who is sick with chickenpox, admits he faked Ken having chickenpox using a sharpie after Cody accuses Junior of making out with Ken and orders him to a fight; Cody still refuses to believe him.
  • Cast Fullof Gay: A lot of the characters in the videos have moments of this. This includes Cody, Brooklyn Guy, Chef Pee Pee, Harry, Mr. Goodman, Jeffy, etc.
  • The Cat Came Back:
    • No matter what Mario tries in order to get rid of Jeffy, he always fails. This sometimes happens in the case where he tries to lure Jeffy somewhere far away.
    • Taken to an even bigger extent with Hansel who, in "Mario's Hobo Problem!", always reappears next to Mario regardless of where he came from, whether it be a locked bathroom or outdoors.
  • Cheaters Never Prosper: In "Jeffy's Punishment!", Mario tries to cheat and make Jeffy break his end of the deal, which is Jeffy gets to shock Mario if he doesn't misbehave for a whole day, by wetting Jeffy's bed so it would appear as if Jeffy urinated in his bed. Jeffy manages to catch Mario red-handed seconds before he can pour the water on the bed. Not only that, Mario gets shocked for trying to set Jeffy up to fail, along with making him eat green beans, and trying to make him get in trouble at school (which Bowser did, not Mario).
  • Chekhov's Gun: Jeffy's iPhone, which he later uses in "Jeffy's Bad Word!" to call 911 and end up getting Mario arrested as a result.
  • Cloudcuckoolander: Many characters;
    • Jeffy is the most prominent with his weird behavior, such as slapping his diaper frequently.
    • Cody, who believes his Ken doll is real and shows Ambiguously Gay traits himself.
    • Shrek, who calls everyone "Donkey" and is obsessed with cheesecake and taking a dump.
  • Cluster F-Bomb: Although, as of the 2017 Adpocalypse, these gags have died out.
    • Chef Pee Pee is prone to saying these when he's mad.
    • In "Bowser Junior's Credit Card!", Goodman repeatedly claims Junior has "fucked him" after the latter reaches his credit card limit and doesn't give the money back from the things he borrowed. And this is only the tip of the iceberg, as Goodman would slowly become foul-mouthed over time.
    • By the time Goodman's "Elephant Asshole" suit debuted, this trope was taken up to eleven, to the point where he had a swearing fit in every single video he appeared in; one example being in The Fender Bender when Mario slightly hits his Lamborghini.
    • Jeffy, as of "Smart Jeffy", is prone to going into swearing rants, such as in "Jeffy Loses His Teeth!" after Mario (disguised as the Tooth Fairy) gives him a dollar for his teeth.
  • Comedic Sociopathy: The show's main type of humor is built around this idea.
  • Comically Missing the Point:
    • In "Bowser Junior's Sleepover", Cody tells Junior and Joseph that his mom still breastfeeds him. Junior and Joseph think it involves chicken.
    • The Brooklyn Guy can partially be this, as well, as shown in "The Grilled Cheese" and "The Pizza Delivery!".
  • Comical Overreacting: Junior seems to feel the need to shout at the top of his lungs where they're going and when they arrive.
    Chef PeePee: We're at Chuck E. Cheese.
    Junior: CHUCKY CHEESE!!!!!!!!
  • Comic Trio:
    • Junior (leader), Joseph (follower) and Cody (complainer) provide a good example, with Junior always coming up with some ridiculous proposition, Joseph being an easily swayed yes-man, and Cody unsuccessfully trying to steer them in the right path.
    • Occasionally Mario (complainer), Rosalina (follower) and Jeffy (leader), with Jeffy providing Insane Troll Logic or arguing against demands by Mario, Rosalina siding with him and supporting his opinions, and Mario himself unsuccessfuly attempting to talk sense into Jeffy.
  • Companion Cube:
    • Cody's Ken doll.
    • Also, Junior's Thomas the Tank Engine toy.
    • In "Cody's Sister!", Cody's twin sister, Katy, is revealed to have a Barbie doll, much like how her brother owns a Ken doll. Katy hasn't even taken her Barbie doll out of its box, though.
  • Cool and Unusual Punishment:
    • In Part 3 of "Mario and Bowser's Stupid and Crazy Adventure", to get Sonic to talk about the whereabouts of Princess Peach, Bowser and Mario do such things as pour tea down the sink, crumple up a picture of the Queen of England, and brush his teeth.
    • In "Cody's Revenge!", when Bowser threatens to send Junior to Military School, some of the punishments the Brooklyn Guy gives to him are to make him listen to Justin Bieber and watch Big Hero 6. Later in the same episode, as part of his blackmail, Cody makes Junior watch the latter on Blu-Ray with him twice.
  • CPR: Clean, Pretty, Reliable: "Bowser's Depression" has Chef Pee Pee performing CPR on Bowser after the latter hangs himself in the bathroom following Charleyyy and Friends' cancelling. Chef Pee Pee even notes it is gross.
  • Crapsack World: Combined with Crapsaccharine World as almost everyone is a Failure Hero, a Jerkass, a borderline Villain Protagonist, or some variation of the three, the populace is easily swayed by the most egregious of lies, and those in higher positions such as Goodman or Brooklyn T. Guy have been respectively shown to be just as self-seeking or downright unhelpful in the worst of times, Goodman in particular being so wealthy and powerful, he's practically untouchable and gets away with being an Ax-Crazy Serial Killer who commits his horrific acts in public. Not to mention, the Purge is a thing in this universe.
  • Crossover: Angry Birds, Shrek, Woody and Hamm and more.
  • Crazy Jealous Guy: The problem for Mario in "Shrek's Coma!" is mainly due to him over-reading into Rosalina's comments about Shrek.
  • Curse Cut Short:
    • Mostly used in the form of Sound Effect Bleeps, but a few instances are uncensored however.
      • "Cool Cody!" took advantage of the Subverted version up to eleven, with just about every cuss in the video uncensored.
    • In "Bowser Junior's Lottery Ticket!", after Junior wins the lottery, the government bans usage of fake IDs, including Junior's (which he has made in an attempt to win). Junior and his friends end up deciding to give the ticket to a stranger and make him give the billion dollars back in return, but the stranger claims the money all for himself. After a moment of them staring in silence, Junior reacts.
    Junior: WHAT THE— (end of episode)
    • "Jeffy's Scavenger Hunt!" ends in a similar way: After finding the last clue and thinking that the prize is a car to go to Disney World with, Jeffy, Junior, Cody, Brooklyn Guy and Chef Pee Pee go to Marvin and Rose to tell them the news. However, Rose reveals that the prize was not a trip to Disney World and it was actually a pack of washable markers. The others then leave, and Jeffy questions that all they worked for was for nothing. Marvin says yes. Guess what happens next?
    Jeffy: YOU MOTHERFU— (end of episode)
  • Darker and Edgier:
    • Any sleepover episode (and the early video "Mario's Nightmare"), being that they have Nightmare Fuel moments.
    • "The Ouija Board!" as well, since it is a source of Nightmare Fuel just like the sleepover videos.
    • Mario and Luigi's Stupid and Dumb Adventures slowly became this as the series went on.
    • "Bowser Junior's Nerf War!" is more action-packed and tense compared to other videos of its time.
    • "Attack of the Killer Shrimp!": A darker, more dramatic, violent and intense retelling of Shrimpo Hunter, as the killer shrimp depicted in this video was played very seriously, alongside an emotional scene where Mario tries to convince Woody to come out of retirement, not to mention the deaths of its victims can be considered Nightmare Fuel. And aside from Brooklyn T. Guy's bad shrimp puns, this episode is very much akin to a horror movie with its dark, intense tone.
    • Both "Jeffy's Parents!" and "Joseph's Mom!" are very much Drama Bombs, given that they revolve around Jeffy's abusive prostitute mom and his suicidal dad in the former, and Joseph's mom disowning him after winning the lottery as well as Joseph's subsequent denial in the latter.
  • A Day in the Limelight:
    • "Chef Poo Poo's Kitchen Disaster!" for Chef Poo Poo, a clone of Chef Pee Pee Junior made with a toaster oven in "Chef Pee Pee's Clone!".
    • In "Joseph's House!", Joseph invites Junior and Cody over to his run-down house when Bowser has his apartment fumigated for termites.
  • Deadpan Snarker: Brooklyn T. Guy. In particular when he's the Millionaire Host, in response to some of the questions given and some of the answers. Like when a $500 question is about how many people died in the Holocaust and one of the answers is 12.
    • Chef Pee Pee can also be this, especially towards Bowser Junior.
  • Demoted to Extra: After Junior and Jeffy ascended to becoming main characters, several other characters were pushed into minor roles, Tony the Tiger and Woody being the most notorious victims. Tony the Tiger was originally a major character, but his appearances got fewer and fewer as time went on. He basically disappeared once the Jeffy era came to be. Mr. Goodman also doesn't appear as often nowadays, demoted to only being a news anchor since Brooklyn took on the role as the guy with several occupations.
    • Chef Pee Pee, Toad, Joseph, Bowser, Shrek, Rosalina, and Black Yoshi were used much less since Jeffy was dropped off at Mario's apartment.
    • Even Mario himself isn't immune to being this, as he was originally the main star of the show before Bowser Junior became an Ascended Extra. As of "Mario the Babysitter!", most episodes involving him are about Jeffy.
  • Depending on the Writer: In spite of it being all done by the same couple of guys since the very beginning, the series has never been consistent with its continuity in any way to the point where it ends up contradicting itself on basic plot points. Most notably, whether or not Mario's gang and Bowser's family share the same house or live in different ones always differs depending on the episode. The most egregious example is "The Human Potion", where Goodman tries to evict Bowser, Junior and Chef Pee Pee even though they're living with Mario, who also houses the non-human Black Yoshi and Shrek and holds the deed to the house.
  • Depraved Kids' Show Host: Doofy the Dragon, who is known for constantly committing suicide in various ways, murdering small animals, telling kids to do cocaine, and even hosting a meet and greet to have a mass suicide!
  • Detention Episode: In "Robot Jeffy", Jeffy gets detention for dirtying his diaper and tossing it at Jackie Chu's face. Cody's robot, Codo, makes a robot of Jeffy named Jeffo to take Jeffy's place in detention so Jeffy can stay in his room and play video games. When Bully Bill bullies Jeffo, Jeffo enters Kill Mode and goes on a rampage.
  • Didn't Think This Through:
    • At the end of "Bowser Junior's Summer School 5", Tanner pulls the fire alarm in an attempt to get out of a test, but it only turns the Brooklyn Guy into a recurring character. And on top of that, he also teaches the class about fire safety the very next day.
    • Twice in "Bowser Junior Needs Glasses!". Junior tries to look into the Sun with a telescope to prove Cody that the Sun is a planet, but gets legally blind from doing so. Later in the episode, Chef Pee Pee tries to make Junior feel better by suggesting that he would read a book so he would "gain knowledge and make himself smarter", but it only worsened the problem, as Junior started acting too smart and literally called his friends and Chef Pee Pee names.
    • In "Bowser Junior's All Nighter!", Junior, Joseph and Cody attempt to drink a whole pile of energy drinks to stay awake, all over a remaining piece of cookie. After they are finished drinking, they get an energy boost, but about 30 minutes later they are completely crashed and exhausted.
    • In "Life Is Ruff!", Joseph and Cody are the first to realize that Junior is in the body of Chompy, his pet chain-chomp. Cody gives Junior two balls; one red and one blue, and tells him to pick the red ball if he really is in Chompy's body. Being colorblind, Junior accidentally chooses the blue ball. Cody later realizes that dogs are colorblind, and even if Junior was in Chompy's body, he wouldn't be able to tell the two balls apart.
  • Ding-Dong-Ditch Distraction: In Part One of "Bowser Junior's Summer School" story arc, it is revealed that the reason that Junior got a B- in attendance (compared to the rest of his report card, which consisted of Fs) was because he and Toad sometimes skipped school to play Ding Dong Ditch, including one time at Bowser's own house.
  • Disproportionate Retribution:
    • In "Toad's Mistake 3", Toad has some of Shrek's cheesecake, a dish Shrek eats constantly and is his favorite food. Shrek chases him while holding a knife, gives him a swirly, craps on him, and murders him in a blender.
    • Steinbeck giving Toad a violent beating all over a paper ball.
    • In "Black Yoshi's Job", when Black Yoshi has to babysit Bowser Junior, he pulls out his gun and shoots Junior's toys when Junior makes him play with one tiny dinosaur against his many bigger ones. He also threatens to pull out his gun again when Junior won't let him play with his Thomas the Tank Engine toy, and even shoots Toad when they play doctor.
    • In "The Call of Duty Problem!", Bowser Junior kills Black Yoshi in a game of Call of Duty, then is dumb enough to tell him his address. Black Yoshi responds by destroying Junior's Xbox One and stealing his Thomas toy.
    • In "Black Yoshi's Call of Duty: Black Ops III!", when Mario buys Black Yoshi a Call of Duty: Black Ops 3 Wii U bundlenote  instead of the PS4 bundle, Black Yoshi destroys the Wii U by shooting it with a crossbow and threatens to kill Mario if he doesn't get him the PS4 bundle.
    • In "Jeffy's Mistake!", both Jeffy and Black Yoshi fell victim to this. The former destroyed the latter's Xbox One by tossing it out a three-story window after dying in a game of Grand Theft Auto, and the latter tied up the former, stuffed a grenade in his mouth and threatened to kill him for doing so.
    • In "Bowser Junior Goes To Military School!", the drill sergeant tells Junior to clean his toilet with a toothbrush and make it so clean that he can eat off of it (which he intends to do). When he eats a sandwich off of the toilet and gets terribly sick, he ties Junior to a post and forces him to watch Big Hero 6.
    • A COUPLE in "Turkey Tyranny!": Obama bans all turkeys and makes them illegal to have on Thanksgiving, just because one attacked him, and Rosalina's parents threaten to wipe out the human race if they don't eat turkey at the Thanksgiving dinner.
    • In "Bowser Junior's Big Vacation!", a humanized and a much more nicer version of Chef Pee Pee plans to kill Junior, just because Chef Pee Pee didn't want to go to the park.
  • Dirty Kid: Both Cody and Toad — especially Cody — are highly and grotesquely perverted.
  • The Dissenter Is Always Right: Rosalina almost always butts in with her own moral objections whenever Mario wants to do something morally incorrect for money, like selling Jeffy to Goodman for a million dollars or staging a robbery to get Brooklyn Guy his job back.
  • Disrupting the Theater: In "Bowser Goes to the Movies!", Chef Pee Pee takes Bowser to the movie theater to see Charleyyy and Friends: The Movie. Bowser is very disruptive in the theater; talking throughout the movie, tossing his food around, and blaming his actions on the other customers.
  • The Ditz: There are many characters who are this, most of these are Insufferable Imbeciles but the more pleasant ones include Mama Luigi and Chef Poo Poo.
  • The Dog Bites Back:
    • Towards the end of "Bowser Junior's Broken Leg!", after pretending his leg is still broken two weeks after it healed to get free stuff from Chef Pee Pee, Junior admits that he's been lying to him for the last two weeks when Doofy the Dragon hosts a meet and greet at the mall, which he wants to go to. Chef Pee Pee beats up Junior to the point of breaking his other leg upon hearing this.
    • In "The Drone!", Cody gives the titular toy to Junior in exchange for Junior's tongue and Chef Pee Pee's eyeball. Cody's response when Junior destroys the drone and wants his tongue back? "No backsies!"
    • In "Cody's Revenge!", after Junior breaks a bowl of Raisin Bran by tossing Cody's Ken doll after losing to him in a game of Super Mario Bros. Chess, Cody snaps a picture of the broken bowl and blackmails Junior with it as revenge for all the bad things he did to him. He makes Junior miserable and forces him to do everything from massaging Ken, to running a bubble bath, to letting him use Junior's golden Thomas, and even making Junior tell Joseph that Ken is absolutely real. When Cody tells Junior to admit that the Sun is a star, Junior finally snaps.
    • A small one in "Jeffy Plays Baseball!"; while Goodman tortures Mario as punishment for reportedly breaking his windshield, not only does he eventually get called out by Mario, but also punched by Jeffy.
  • Dogged Nice Guy: Mario towards Rosalina. Mario is afraid of hurting her feelings so he ends up lying just to keep her happy.
  • Don't Explain the Joke: When Bowser Junior and Chef PeePee are looking at Junior's homework, Chef PeePee notes that the second item on the spelling sheet is a pig. When he asks Chef PeePee, Chef PeePee tells him that it's his mother and bursts into laughter. Junior is confused and tries to explain his mother is a turtle.
  • Don't Make Me Take My Belt Off!:
    • In earlier videos, Bowser would beat Junior with a belt.
    • In "Jeffy's Tantrum!", Mario whacks Jeffy with a belt for throwing the couch and TV off the balcony.
    • In "Cody's Report Card!", when Junior shows Bowser his report card, which has Ds and Fs on it, Bowser hits his pillow with his belt, since he isn't allowed to hit Junior with it anymore. He then says it doesn't feel right, so he has Junior scream as he hits the pillow.
  • Don't Try This at Home: In "The Prank!", Junior and Joseph decide to glue Chef Pee Pee's eyes shut with Elmer's school glue. Cody objects to this prank, saying that Chef Pee Pee could permanently go blind if they try it. Not wanting to be responsible for anyone seeing the episode actually doing this in real life, Cody puts up a disclaimer saying, "DO NOT PUT GLUE IN YOUR EYES!".
  • Double Standard: Abuse, Female on Male: Ever since Jeffy was added to the show, Rosalina got more defensive of Jeffy, to the point where she became an abusive wife to Mario, physically, mentally and verbally.
    • In “Jeffy’s Cellphone!”, When Jeffy calls a prostitute, pretending to be Mario, Rosalina, despite watching the Star Wars movie with him this whole time, thinks that Mario is cheating on her, and proceeds to beat him.
    • Rosalina has at least five exes including D-Money and Super D, but when Mario feels uncomfortable with them being so playful around her, Rosalina simply shrugs it off as jealousy. On the other hand, if Mario’s phone or doorbell so much as rings, Rosalina immediately assumes it’s another woman (note: Mario has only one ex that he hasn’t been with since 2015).
  • Downer Ending: There is a 90% chance a video will either end on this note or simply have No Ending. For a full list of examples, go here.
  • Dream Intro: "Mario The Babysitter!" starts with Bowser kidnapping Rosalina, when Mario appears in a Superman suit and defeats Bowser with his hair. When he grabs Rosalina, they both bump into a wall and Mario instantly wakes up. He is less than amused to find that it was just a dream.
  • Driven to Suicide:
    • Bowser hanged himself when Charleyyy and Friends got cancelled.
    • Mario was so incredibly upset about not having a girlfriend that he attempts to commit suicide. Bowser admits he only saved him because he wants to kill him himself, which doesn't particularly make Mario feel any better since Bowser is basically only saving him out of inconvenience.
    • Doofy the Dragon is this trope who gets himself killed in the show, purely for laughs.
    • In "Jeffy's Tantrum!", Jeffy becomes emo and attempts to hang himself with a rope two weeks after Mario hits him with with a belt for throwing a TV off the balcony when Mario refused to buy him a SpongeBob SquarePants game from the App Store. Fortunately for Jeffy, Junior gives him a $10.00 iTunes gift card so Jeffy can buy the game himself.
  • Dude, Not Funny!:
    • In "April Fools!", Junior decides to pull a prank on Chef Pee Pee by telling him his mom died. Needless to say, Chef Pee Pee doesn't take it lightly, and later retaliates by pulling his own prank on Junior using his Thomas toy.
    • In "Jeffy's Stupid Home Video!", Mario submits his entry to America's Stupidest Home Videos, but as his entry ended up being rushed & consisting of him hitting Jeffy with a hammer in an attempt at Slapstick, the audience and host find it disturbing rather than stupid or funny, and the baby entry ends up winning for the second time in a row.
  • Dumb Blonde: Rosalina as of "The Pizza Delivery!" has been characterized into a stereotypical, annoying airhead obsessed with stars and later on having anything star related. Although as of "Mario The Babysitter!", she mostly sides with Jeffy despite Mario being the more smarter one in the trio.
  • Dysfunctional Family: This is common place in the SML universe; in fact, just about every main character's family is borderline deranged.
    • In spite of being one of the most sensible characters, Mario gradually becomes a short-tempered husband thanks to his wife, a Dumb Blonde named Rosalina, who always suspects the worst of Mario, and his incredidbly dimwitted adopted son that is Jeffy, who has gotten him in trouble with the law several times.
    • Bowser is the father of Bowser Jr., but he rarely is involved with Junior's life as he spends most of his free time watching Charleyyy and Friends. When he is being a father, he usually beats up or severly punishes his son. And that's not even accounting for their tendecies to treat Chef Pee Pee horribly.
    • Any glimpse of Brooklyn T. Guy's family has showed it to be highly dysfunctional. His wife always shouts into his ear, his brother is a perverted idiot who consistently fights with him, his mother does nothing but demean him, and Brooklyn's own daughter dislikes him because of his negligence. And in a few episodes, Brooklyn Guy is revealed to have many other siblings, with two of them nearly killing Mario's family on seperate occasions.
    • Cody's parents consistently cheat on each other, and in one episode, they expressed joy at the (false) news of Cody being dead.
    • It goes without saying that Joseph's homelife is awful. He seemingly killed his own mother, and his father seemed to mysteriously died as well, only to be revealed that his mother faked her own death just to abandon her son.
  • Ear Ache: In "Bowser Junior's Painting!", Pierre François cuts his own ear off and puts it onto a black canvas in an attempt to improve it. Needless to say, Goodman is impressed yet still shocked.
  • Early-Installment Weirdness: Some examples:
    • The very early videos (which dabhdude nicknamed 'The Old Era') were a lot simpler compared to later ones, due to the aforementioned videos mostly just being unscripted. For example, one video is just simply about Mario and Tony watching Blue's Clues on the TV. Another video is literally just random SML characters dancing to Caramelldenson.
    • In his first appearance "Koopa's New Job", Chef Pee Pee was a dimwitted chef who loved working for Bowser, but as the series went on, especially with the introduction of Bowser Junior, Chef Pee Pee became smarter and grew to hate Bowser and Junior for treating him badly.
    • A more recent example: Rosalina in her first few appearances cried at daytime because she could no longer see the stars, but as of "The Pizza Delivery!" she became more of a stereotypical ditzy blonde afterwards.
    • Bowser originally was the main antagonist who terrorized Mario and the gang and was after Princess Peach like his canon counterpart, but eventually, that was toned down and Bowser rarely terrorizes Mario and others if at all, even to the point of letting Mario move in his own house.
    • Bowser Junior in his first appearance in "Baby Mutant Turtles" is barely anything like the spoiled, obnoxious character that he became in later episodes. In fact, his debut is more of an action-packed explosion movie-style video than anything else in his following appearances.
    • Goodman was originally the character with multiple jobs who would deal with most characters if they needed for example a cop or a medic for aid, but eventually Brooklyn T. Guy would slowly take over Goodman's role from 2014 onwards, with Goodman rarely appearing in newer episodes. And in the episodes that Goodman does appear he has appeared to be Flanderized into an idiot, and eventually, a foul-mouthed Corrupt Corporate Executive who took Bowser's position as Big Bad and is an even bigger Karma Houdini than Jeffy, always getting away with tormenting Mario (such as extorting him and claiming they're "house payments") because he's so rich, he can bribe the police with impunity, and the police happily accept because the entire department is corrupt. He eventually developed a cannibalism fetish involving eating human testicles and nipples.
    • In early videos, Cody starts off as a smart Sickly Neurotic Geek, but now his medical issues are rarely touched upon and he's now more of a gay pervert and the sane man to Joseph and Junior. This was lampshaded in "Chef Pee Pee's Kids".
    • In early videos, Bowser used to have Goombas and Koopas as minions like his canon counterpart, but by 2014 they started to appear less and less, till they stopped showing up.
    • Prior to the events of "Bowser's House Fire!" and "Mario's Family Moves Out!", both Bowser's family and Mario's family were established to be living in different (yet similar) houses.
    • In early videos prior to the overhaul of the series, Mario determines whether or not the games in his console collection are good. The bad stack, as always, gets eaten by Yoshi. Occasionally, Yoshi would even eat the camera.
  • Easter Special:
    • "Bowser Junior's Easter Egg Hunt" has Junior challenge Bowser to an Easter egg hunt.
    • "Bowser Junior's Easter Wish!" has Junior wish that Chef Pee Pee was the Easter Bunny.
    • "Jeffy's Special Easter!" has Rosalina and Mario, the latter of who believes Easter to be a commercial holiday, celebrate it with Jeffy.
  • Easy Come, Easy Go: Happens almost EVERY time a character wins a great amount of money.
  • Eat That: When Mario became a donkey once, Shrek forced him to drink his poop through a straw as retribution for not bringing him toilet paper.
  • Electrified Bathtub: In "Bowser Junior's Sleepover", at the end of the first episode of Doofy the Dragon, Doofy kills himself by putting his hairdryer in his bathtub. Then a disclaimer shows up, warning the viewers not to attempt what Doofy did.
  • Embarrassing Damp Sheets:
    • In "Bowser Junior Gets Potty Trained!", Junior awakens to find his bed wet, and immediately jumps to the conclusion that he's a mermaid. Chef Pee Pee isn't fooled, and he tells Junior that he wet the bed. The rest of the episode deals with Junior being forced to wear diapers by Bowser, since he is unable to use the toilet properly at first, until Toad teaches Junior how to use the toilet through a rap song.
    • Junior wets his bed again in "Chef Pee Pee's Birthday Surprise!", after he has a dream about the Statue of Liberty, due to the fact that it's surrounded by water.
    • In "Joseph Moves In!", Joseph pees all over Junior's pillow, mistaking it for a toilet. When Junior tells Chef Pee Pee about it, Chef Pee Pee doesn't believe him and thinks he's blaming Joseph.
  • Embarrassing Relative Teacher: In "Substitute Teacher!", Judy becomes the substitute teacher for Bowser Junior's class when Jackie Chu becomes sick. She embarrasses Cody to no end, by telling him that he forgot to take his medication that keeps him from wetting his pants, revealing their surname (Nutkiss), making him read a note Junior passed him in front of the class, and teaching the class about The Nazi Cheeseburger and marine biology (with all of her knowledge of the latter being from SpongeBob SquarePants).
  • Everyone Has Standards: Both Mr. Meaner and Bubbles are shown to be very afraid of the crime Junior committed in the video "Junior's Essay", said crime being sneaking snacks into a movie theater.
  • Everyone Owns a Mac and Everybody Owns a Ford: Almost every single non-gaming tech product is a Mac or iOS device. Apparently, everyone also drives the same red Corvette / Lamborghini that Logan himself owns.
  • Everything Is Racist: The entire plot of "Cody’s Bad Word!", in which Cody is constantly berated for being racist (this starts with him saying "inward", and escalates to him being shamed for coloring a mermaid white, saying that black cats are bad luck, and choosing Obama over Lincoln as his favorite president).
  • Evil Twin: In "The Secret Door!", it's revealed that Brooklyn T. Guy has an Ax-Crazy, evil identical twin brother named Does Bad Things Guy, of whom Mario thought was the real Brooklyn.
  • Eye Cam:
    • Used when Sonic wakes up in Part 3 of Mario and Bowser's Stupid and Crazy Adventures.
    • Also used when Mario regains consciousness in "The Secret Door!" after getting knocked out by Does Bad Things Guy.
    • Used with Jackie Chu in "The Test!". As he claims his eyes are so slant that he cannot see, well...
  • Eye Scream: Logan seems to think ocular injuries are funny.
    • Chef Pee Pee suffers it in "Bowser's Cookies" when Toad stabs his unprotected eye with a KNIFE and tries to fix it with a Band-Aid.
      • Happens again in the same episode at the end when Bowser sticks a fork into Chef Pee Pee's other eye apparently rendering him unable to see, but he somehow recovers in the next episode.
    • Chef Pee Pee suffers it again in "Bowser Junior Goes To Disney World!", after Junior finds the knife in a box of Doofy-O's that wins him a trip to Disney World.
    • Chef Pee Pee suffers it yet again in "The Drone!" and ends up with one of his eyeballs removed out of its socket.
    • Bowser Junior suffers it in "Bowser Junior's Happy Meal", when Chef Pee Pee tricks him into playing a game with the pair of scissors he tries to pass off as a Happy Meal toy.
    • Junior suffers it again in "Bowser Junior Gets his Nose Pierced!" when Cody accidentally pokes him in both his eyes when attempting to pierce his nose with a toothpick (which isn't shown to the viewers).
    • Bully Bill suffers it in "Bowser Junior Learns Karate!", when Junior uses chopsticks under the advice of Jackie Chu.
  • Failure Is the Only Option: Significantly, almost every Jeffy episode partly or completely relies on this.
    • In "Where's Jeffy?", Rosalina leaves Mario in charge of both Jeffy and her necklace while she goes to visit her parents for three days, and puts her necklace around Jeffy's neck. Mario takes Jeffy to the park, then leaves him there and rushes back to his apartment, happy to have Jeffy out of his life. Shortly afterwards, Mario realizes he doesn't have Rosalina's necklace, so he calls her to ask her where she left it, and she tells him she left it around Jeffy's neck. Mario rushes back to the park to find Jeffy upon hearing this...
    • "The Hitman" focuses on Mario hiring the Loan Dolphin to kill Jeffy. He first tries to get the Loan Dolphin to shoot Jeffy at the park while he's holding an ice cream cone, only for Jeffy to throw away his cone, leading to the dolphin shooting another kid instead. The second attempt involves the dolphin giving Jeffy poisoned Chicken McNuggets at a drive-thru, but Jeffy's insistence on having 20 toys come with his food causes him to throw it away. The Loan Dolphin then tries to break into Mario's house and kill Jeffy outright (courtesy of Mario intentionally leaving the door unlocked), but Jeffy ends up calling 911 and ultimately has the police getting the dolphin caught and arrested.
  • Faint in Shock: Mario in "Jeffy's Sister!", over the stress of both Jeffy and his sister Feebee losing his house.
  • Fake High: In "Root Beer!", Junior and his friends get drunk off the titular drink. Brooklyn T. Guy even lampshades it at the end of the video by saying that they only got drunk because they were stupid.
  • Fantastic Racism: The audience is never actually told what "Folk" means, but apparently it can apply to virtually everything that isn't a Yoshi if how often Black Yoshi uses it is any indication.
  • "Fantastic Voyage" Plot:
    • In "Jeffy Gets Stung By A Bee!", Mario and Brooklyn T. Guy go inside Jeffy in attempt to retrieve a "banana butterfly" (which Jeffy HAD swallowed after all).
    • In "Jeffy's Cat Piano Problem!", after Mario takes Jeffy's cat piano away and hides it, Junior gives Jeffy the idea of going inside Mario's brain and controlling him so he can convince Rosalina to tell him where his cat piano is.
  • Feud Episode: In "The School Project!", Junior gets into a feud with Cody after the latter accidentally breaks his toy helicopter, as Junior insists that Cody did it on purpose. When Jackie Chu catches them fighting in class, he makes both of them work on a solar system project together as punishment. Junior also tries to use Joseph as a proxy.
  • Firefighting Episode: In "Bowser's House Fire!", Bowser's house catches fire thanks to a candle Junior lit after watching an episode of Doofy the Dragon where Doofy lights himself on fire. Brooklyn T. Guy attempts to put the fire out, but because the Fire Department cut his funding the previous month, he couldn't afford a fire truck, so he had to use his own car to rush to Bowser's house and Bowser's garden hose to put out the fire. By the time the fire is put out, Bowser's house is burnt to the ground, forcing Bowser, Junior, and Chef Pee Pee to move into an apartment.
  • Flanderization:
    • Junior's first appearance has him battling the good guys akin to a dramatic action movie, and attacking with the same way that the Super Mario Bros. Bowser would do to Mario. Starting from "Bowser Junior's Macaroni", he becomes a Spoiled Brat who lives with Bowser and Chef Pee Pee, and technically keeps annoying both of them while hanging out with his friends Joseph and Cody.
    • The show's mean-spiritedness took a step in this. The torture of Mario and Pee Pee has amped up over time as well.
    • Rosalina is more of this herself. In her first few appearances, she was addicted to seeing stars, and would continually sob when they go out. Since "The Pizza Delivery!", she was more of a stereotypical ditzy blonde, and as of Jeffy's debut, she was shown to be more caring towards him while Mario gets called out.
    • Though most fans won't recognize this, Brooklyn T. Guy, in an SML Short released in 2011, was shown to be heroic but stupid, as he failed to save Toad because he got distracted by a phone. He becomes more of a Deadpan Snarker and Jerkass afterwards from "Bowser Junior's Summer School 5".
  • Foregone Conclusion: Every episode of Doofy the Dragon ends with him killing himself, typically by gunshot, but other ways have happened. In the episode "Bowser Junior's Broccoli Problem!", Junior notes that Joseph and Cody can't leave until they see how Doofy the Dragon ends today. Joseph notes that he just always kills himself so there's no secret. The group are bothered by a crocodile who is then forced to explain the difference between a crocodile and an alligator after the three think he's an alligator. When they return to the television, Doofy the Dragon is over and Junior notes he doesn't know how it ended. Joseph yells at him that "he just dies!".
  • Foreshadowing:
    • At the end of the final episode of Bowser Junior's Summer School, Principal Steinbeck tells Junior that they'll meet again. Sure enough, they do in the first episode of Bowser Junior's 1st Grade!.
    • Double foreshadowing occurs with Charleyyy and Friends: The Movie, first in "Bowser Junior's Nerf Gun" where the trailer for the movie is shown, and then in "Bowser Goes To The Movies!" where at the end Bowser mentions looking forward to the movie coming out on DVD, which eventually happens in "The Christmas Special!".
    • In "Broken", when Junior shows Joseph and Cody his new playroom, the letter magnets on the whiteboard are arranged to say "KEN DIES". Sure enough, Ken falls off the balcony and breaks in half.
  • Fourth-Wall Observer: Bowser Junior, more often in the 2016 videos.
  • "Freaky Friday" Flip:
    • "Switching Bodies!" has Bowser Junior and Chef Pee Pee switching bodies after wishing what's it like to be each other. Hilarity Ensues, surprisingly.
    • In "Life is Ruff!", Junior and his pet chain-chomp, Chompy get hit by a truck (driven by Woody, no less), and they somehow end up in each other's bodies.
    • In "1 2 Switch Bodies!", a lightning bolt strikes Junior and Jeffy while they are playing 1-2 Switch on the Nintendo Switch, switching their bodies as a result. At the near end of the video, the exact same thing happens to Chef Pee Pee and Cody.
  • From Bad to Worse: The initial main conflict of "The Bake Sale" is just about raising enough money to afford for Joseph's medical bills after a stunt gone horribly wrong, but Junior's incompetence results in the situation spiraling into this, from injuring Chef Pee Pee and breaking Cody's glasses, thus adding on even more money to raise. Unsurprisingly, Junior and Cody fail to obtain as much as a single dime, and it's only thanks to Goodman that they're able to turn things around.
  • The Friend Nobody Likes: This applies to people entirely depending on the situation, such as Mario hating Shrek but still being around him, and Joseph and Junior treating Cody like garbage because he's so weird.
  • Fun with Flushing:
    • In "Bowser Junior Gets Potty Trained!", as Toad teaches Junior how to use the toilet through a rap song, he puts the diaper Bowser forced Junior to wear in the toilet, and at the end of the episode, he and Junior flush the diaper down the toilet.
    • In "Bowser Junior's Annoying Toy!", Junior annoys everyone by playing with a ball popper toy. Fed up with this, Black Yoshi takes the balls out of Junior's ball popper and forces Junior to flush them down the toilet.
    • In "Bowser Junior's Broccoli Problem!", Junior gets rid of the broccoli Chef Pee Pee makes him eat by flushing it down the toilet. It only worsens the problem, as the broccoli lands in the mouth of a crocodile who lives in the sewers, thus causing him to infiltrate Junior's house in search of more food.
    • In "Bowser's Goldfish!", Junior plays with Bowser's pet goldfish, Charleyyy Jr., in the bathtub, until Toad arrives and tells Junior that they could take CJ on a water slide. Toad's idea on water slides for fishes, however, is flushing them down the toilet. Junior is against this, but Toad tells him that all toilets have a mechanism in them that keeps fish from getting flushed down. When Junior can't bring himself to flush the toilet, Toad does so, flushing CJ down it. When CJ doesn't come back out, Toad blames Junior for not having a toilet with a fish-catching mechanism. At the end of the episode, CJ comes back up the toilet, having grown massively in size, wanting revenge on Junior for flushing him.
    • In "Jeffy's Stupid Home Video!", Jeffy thinks he's trapped inside Mario's camera after Mario shows him a video he filmed of him swinging from the ceiling fan. In an attempt to get himself out of the camera, he flushes it down the toilet, destroying the camera as a result.
    • In "Cody The Magician!", when Junior and Joseph repeatedly misunderstand Cody's card trick, a frustrated Cody tells them to do anything other than show him or tell him what it is. Junior takes the 6 of Clubs card and flushes it down the toilet, but it gets stuck in the hole. When Junior gets back to Cody, Cody somehow has the 6 of Clubs card with him.
    • At the beginning of "Bowser Junior's Curse!", Junior tells Joseph and Cody that Bowser bought a toilet that can flush 18 golf balls. Cut to Junior doing just that.
  • Getting Suspended Is Awesome:
    • In "Jeffy Gets Bullied!," Jeffy gets suspended for beating up Bully Bill. When Mario tells him that he has to stay home for a week, he's happy about it, saying that he should have gotten himself suspended a long time ago.
    • Similarly, in "Jeffy Gets Expelled!," after being expelled for fighting too many times (as well as being placed under house arrest due to Bully Bill pressing charges), Jeffy is thrilled that he doesn't have to go to school anymore. He gets upset when told he has to go back after putting his ankle bracelet on Bully Bill and causing him to blow up.
  • Go-Karting with Bowser: Or rather, in this case, living in his house.
  • Gleeful and Grumpy Pairing: Bowser Junior and Chef Pee Pee have this respective dynamic. Junior loves making Chef Pee Pee play games with him, take him fun places, and cook food for him. Chef Pee Pee, however, hates having to look after Junior, especially because it's one of the many responsibilities that Bowser gives him.
  • Good Behavior Points:
    • In the episode "Jeffy the Good Boy!", Jeffy wants to get a Playstation 5 and an Xbox Series X. Rosalina comes up with the idea for a good boy chart, where Jeffy will earn a gold star for good behavior, and lose one for bad behavior, and if Jeffy successfully gets 25 stars, then Mario will buy him one of the two new consoles. Black Yoshi hears about this, and tries to make his own "gud Boi Charp" with 50 stars on it so he can get the consoles, which Mario doesn't fall for. Black Yoshi later tells Jeffy to trick both Rosalina and Mario by stealing the gold stars and putting them on the chart, then showing it to each of them so that they'll give him one of the two consoles. The plan works, as Mario buys Jeffy a PS5 and Rosalina buys Jeffy an Xbox Series X. When Rosalina and Mario find out they each bought Jeffy a console, they find out about Jeffy and Black Yoshi's trick, and punish them both by playing the consoles right in front of them and not giving them a turn, given that they paid for the consoles with their own money.
    • In "First Day of School!" Jackie Chu is the teacher at Y U Dumb? Elementary School, and has a gold star chart for each of the students. He gives his students gold stars for following directions and takes them away for bad behavior. He also explains that the student with the most gold stars will get a special surprise at the end of the year. On the first day, he gives Bowser Junior, Cody, Jeffy, Toad, Toadette, Patrick, and Atso gold stars for writing their names on their name tags on their desksnote  He doesn't give Joseph a gold star for writing "Adolf Hitler" on his name tag, and he doesn't give Bully Bill a gold star for crumpling up his name tag into a ball. Later in the episode, Jackie Chu takes Junior's gold star away for knocking Joseph's desk over, and puts him in the negative star category for knocking Cody's desk over. He also takes Jeffy's star away after Jeffy swears at him when he gives all the students homework.
  • A Good, Old-Fashioned Paint Watching: As a 2017 April Fool's joke, "SuperMarioLogan The Movie!" is revealed to be Jeffy painting a fence and then watching the paint dry for an hour. It even includes moving shadows!
  • Gonk: Jeffy, Nancy, and to a lesser extent, the Francois family in general. Also the custom puppets to an extent.
  • Grand Finale: SML has made a few series that have ended this way:
    • Black Yoshi and the Birds ended with Episode 7, where Mario teamed up with the Pigs to kick the birds out of the house, while Black Yoshi was woken up by the Pigs' leader, Mr. Pig, after getting knocked out in the previous episode.
    • Before it was Un-Cancelled (which technically makes it a Series Fauxnale), Mario and Luigi's Stupid and Dumb Adventures had finished with the Season 2 finale, where Mario had planned to go back in time to stop everyone from dying. In the end, he jumps into a portal to accomplish his plan, with some help from a Yoshi. The season itself ended with a brief clip from the very first episode of the series.
    • The final episode of Bowser Junior's Summer School was Episode 7 (very much like Black Yoshi and the Birds), in which the summer school Junior was attending had their final exam, and Junior was at risk of failing, so he conjures up a plan along with Chef Pee Pee. However, the plan soon fails, and Junior ends up taking the only other option to pass the class: "killing the fly".
      • "Bowser Junior's Summer Vacation" acts more as a Grand Finale to the series as a whole, where Junior and his friends celebrate the passing of summer school.
  • Greens Precede Sweets:
    • In "Shrek's Diet!", Shrek suffers a heart attack as a result of eating too much cheesecake, so under the advice of Dr. Brooklyn T. Guy, Mario puts Shrek on a diet and makes him eat salad. Mario tells Shrek that if he eats all of his salad, he will let him have a bite of cheesecake for dessert, but Shrek would much rather eat cheesecake first. Because Shrek really refuses to eat his salad, Mario and Chef Pee Pee have to tie him down and force-feed him.
    • "Jeffy Gets Potty Trained!" begins with Rosalina trying to get Jeffy to eat peas. Jeffy tells Rosalina that he doesn't want to eat peas and that he wants to eat marshmallows instead. Rosalina tells Jeffy that he can't have marshmallows until after he eats his peas.
    • "Locked Out!" begins with Mario serving Jeffy peas for dinner. Jeffy tells Mario that he doesn't want to eat peas and that he wants to eat chocolate cake instead. Mario tells Jeffy that he can't eat chocolate cake unless he eats his peas first. Jeffy tries to fool Mario by hiding his peas in his high chair, but Mario soon finds out. Mario then decides to taunt Jeffy by eating chocolate cake in front of him, but Jeffy retaliates by tricking him into going outside and locking him out of his house.
  • Grossout Show: Oh, yes. It's not overtly pronounced like many other examples are, but there are more than enough videos (and characters) that dip into the revolting, especially from 2014 and onward, to put the series firmly in this territory.
  • Growling Gut:
    • Happens to Rosalina in "The Pizza Delivery!".
    • Happens to Shrek in "The Bird" and "Baby Shrek".
    • Chef Pee Pee's stomach growls due to diarrhea in "Chef Pee Pee's Clone".
    • Happens to Junior in "Bowser Junior's Midnight Snack!" and "Bowser Junior's Happy Meal 2".
    • This happens to Shrek, Mario, and Rosalina in "The Couch!" after they all ate or drank expired things, causing all of them to poop on the couch.

  • Hair-Trigger Temper: Chef Pee Pee and, to a lesser extent, Bowser.
    • Principal Steinbeck from "Bowser Junior's Summer School" and "Bowser Junior's 1st Grade". He has a big opportunity to hurt or insult a student.
    • Mario is prone to this when around Jeffy.
    • Mr. Goodman when it comes to the value of money, particularly Mario's "house payments".
    • Jeffy is a good example. If he doesn't get his way or is punished (which happens a lot), it almost always results in a swearing rant. There's a reason why his Catchphrase is "ARE YOU FUCKING HIGH?!"
  • Half-Human Hybrid:
    • Chas and Junior Jr., the offspring created from Chef Pee Pee and Cody's, and Chef Pee Pee and Junior's DNA by the Baby Machine respectively in "Chef Pee Pee's Kids".
    • Jeffy Jr.note  in "Pregnant Jeffy!", created with Harry's impregnation machine using Junior's DNA.
  • Halfway Plot Switch:
    • "The Burger!" initially starts with Junior and his friends playing baseball inside the apartment. Cody gets a home run and the ball falls behind the refrigerator. Junior and Joseph find the baseball...only to completely forget about it afterwards when they notice the titular burger next to it.
    • "Jeffy's Wifi Problem!" involves, well, Mario changing his WiFi password and Jeffy trying everything he can to get his Internet back. At one point, he calls Brooklyn T. Guy in an attempt to retrieve the password from Mario, which ultimately devolves into a subplot where Brooklyn scams $800 out of a Foosball table from both Mario and Jeffy.
    • “Jeffy’s Online School!” starts off with Mario signing Jeffy up for online classes because of a certain pandemic. This turns out to be the link to an elderly stripper acting as a teacher. Once Rosalina catches Mario looking at her, the video turns into Mario trying to convince Rosalina it was an accident, and Rosalina constantly berating him for it at every turn.
    • "Jeffy Recycles!" starts with Mario and Rosalina teaching Jeffy how to recycle... until Goodman then shows up asking Mario to watch him his ship-in-a-bottle, and the plot eventually devolves into Mario trying to get Brooklyn T. Guy to make a new ship-in-a-bottle for him after Jeffy ends up destroying the other one.
  • Hate Sink:
    • David Winkle, Bowser Junior's perverted 1st grade teacher from Parts 2 and 3 fits this trope. A convicted sex offender, Mr. Winkle uses his job as an outlet for his sexual attraction towards children. Telling children to bring their underpants to school for a "science experiment," taking informal pictures of classmates to pleasure themselves to them, and blatantly raping a child in the bathroom will surely make your character unappealing to most people.
    • Nancy, Jeffy's extremely abusive mother.
  • Hated by All: In "Who Wants to Be a Millionaire? Part 2", Craig the Devil uses a lifeline to ask the audience to help him answer a question. All four answers result in 0%, and the Brooklyn Guy asks the audience if their keypads are broken. He soon finds out that the audience deliberately chose not to help Craig. It doesn't help that the audience starts booing upon Craig's entrance, and he is also friends with Adolf Hitler.
  • Here We Go Again!:
    • Subverted in "Bowser's Depression", where Bowser goes into depression when his favourite show Charleyyy and Friends gets cancelled and replaced with Fishy and Friends. Bowser eventually gets over it when he watches a video made by Junior and Chef Pee Pee, and later gives the latter show a chance and begins to like it, only for it to get cancelled. When it looks like Bowser is about to go into another breakdown, it is revealed Charleyyy and Friends was renewed, much to Bowser's relief.
    • In "Black Yoshi's In Trouble!", Mario spends the entire episode trying to turn Black Yoshi into a better person, due to Black Yoshi having a court date in where if he doesn't go straight in his personality, he will be sent to jail for life. When the court lets him go, Black Yoshi immediately reverts back to his old ways, much to Mario's dismay.
    • At the end of "Bowser Junior Loses Thomas!", Chef Pee Pee finds Junior's Thomas toy and gives it back to Junior. A few minutes later, Junior loses the dinosaur toy he played with at the beginning of the video and calls for Chef Pee Pee to help him find it.
    • In "Shrek's Diet!", Mario forces Shrek to go on a diet and go to the gym after Shrek's daily diet of cheesecake gave him a heart attack. At the end of the video, while he and Mario eat cabbage salad when it appears Shrek has finally accepted this healthier lifestyle, he grabs some cheesecake, eats it and gets fat again, much to Mario's disappointment.
    • At the end of "Bowser Junior's Broken Leg!", Chef Pee Pee beats Junior up to the point of breaking his left leg after finding out that he was lying about his right leg being broken.

    • In "Bowser Junior's Cookies!", after a whole shenanigans full of sticky notes saying "cookies" all over the apartment and Chef Pee Pee raging, he finally goes to the store and brings cookies for Junior, only to find out that the kind of cookies were not what Junior wanted, and he really wants Chips Ahoy cookies. Junior then starts writing "Chips Ahoy" on the sticky notes and sticks them for a second time.
    Chef Pee Pee: Not again!
    • At the end of "Bowser Junior Gets Rabies!", a rabid Junior bites Chef Pee Pee, causing him to catch rabies from him, and he later gets the same symptoms Junior had from the disease. Junior and Cody do not care though and then start poking him with a stick.
    • The ending of "Bowser Junior's Package!" has Brooklyn T. Guy stealing Junior's gak. This results in Junior going into a rage, similar to when he accused his friends, Chef Pee Pee and Bowser of stealing his package throughout the entire video.
    • "Bowser Junior Stubs His Toe!" has Junior stubbing his toe on the table. This causes his left leg to be put in a cast and he ends up in a wheelchair. As a result, Junior goes into depression since he no longer can walk, but when Joseph and Cody point out he still has one good leg, Junior realizes he can still walk, and Joseph and Cody encourage him to get out of his wheelchair only for Junior to step on a LEGO brick, causing his other leg to be put in a cast.
    • In "Broken", after Ken falls down from the balcony, he breaks in half and "dies", causing Cody to go into depression. Having had enough of Cody crying and repeatedly saying "in half", Joseph and Junior decide to fix Ken, by managing to put Ken back together using his one piece tuxedo. They warn Cody not to take his clothes off, but later that night Cody decides to take a bath with Ken and takes off its clothes, causing Ken to break and "die" again. As a result, Cody goes into another depression.
    • In "The Ring", Mario buys a ring which he intends to use to propose to Rosalina, but when Rosalina arrives home early, he tells Jeffy, of all people, to hide the wedding ring. As Mario distracts Rosalina, Jeffy's hobby of throwing stuff causes him to lose the ring as it ends up in Shrek's homemade cheesecake. When Mario finds out what happened, he spends the entire episode trying to make Shrek poop, but when Chef Pee Pee shows Mario that Shrek didn't eat the ring, he and Mario clean it up, only for it to fall down the drain...
    • In "Forsaken", the sequel to "Broken", Cody assumes that Junior and Ken have a thing for each other, then he has Ken pick either him or Junior. Soon enough, Ken falls on Junior's lap and Cody is reduced to sobbing thinking that Ken no longer loves him. Later, Junior pretends he's breaking up with Ken, so that Cody can stop sobbing, and when Junior leaves the couch, Ken falls on Joseph's lap. Cody assumes Ken prefers Joseph and breaks down crying.
    Cody: My heart is broken...IN HALF!!!
    • In "The Bake Sale!", after Joseph gets all his bones and skeleton broken after falling from the roof, Junior and Cody try to bake cookies to sell them in order to raise money for Joseph's insurance, which is about $50,000, only for Junior to cause several consequences, including giving Chef Pee Pee half of the money if they manage to heal Joseph, getting into a freak accident which results in Chef Pee Pee getting third-degree burns all over his body, and buying $100 worth of cookies, thus raising the insurance up to a good $125,100. After they manage to get all the money for both Joseph and Chef Pee Pee, Junior tells Joseph and Cody if they want to go lay down in the middle of the road. Although Joseph and Cody survive, Junior ends up getting all his bones broken, as Joseph and Cody go to bake more cookies to pay for Junior's medical insurance.
  • Heroic BSoD:
    • In "Bowser's Christmas Problem", Junior gets one after annoying Bowser to the point where he yells at him that Santa does not exist, breaking him.
    • Chef Pee Pee has a breakdown at the end of "Bowser Junior's Caprisun", after wasting his break trying to open Junior's Caprisun and ultimately having his food confiscated by Bowser.
    • Junior again in "The Christmas Special!" upon realizing that he didn't receive a golden Thomas the Tank Engine toy from Santa. Doesn't help that Chef Pee Pee and Bowser don't remember Junior demanding them for the toy.
    • Chef Pee Pee gets a second brief one in "Black Yoshi's Girlfriend Problem!" when Birdo makes a mess in the kitchen upon coughing up an egg. He recovers shortly after that.
  • Historical In-Joke: Jeffy has caused the killing of Harambe, as shown in "Jeffy Goes To The Zoo!". Additionally, Mario is heavily blamed for bad parenting despite convincing that it's the zoo's fault for having bad infrastructure.
  • Hollywood Restraining Order: In "Mario's New Girlfriend!", Mario gets a restraining order from Princess Peach, stating that he is not to go within five miles of her. When Peach drops by to pick up her missing thong, Mario asks her if she sent the restraining order by mistake, but Peach assures him that she meant to send it. At first, Mario is desperate to have Peach back, but with help from Black Yoshi, he starts dating Princess Rosalina, and the two continue dating in later episodes. Also in the same episode, Black Yoshi tells Mario that he has his own restraining order from his ex-girlfriend, stating he is not to go within six miles of her.
  • Huge Rider, Tiny Mount:
    • In Part 3 of the "Mario and Bowser's Stupid and Crazy Adventure" story arc, after Bowser successfully hatches a Yoshi, Mario coaxes the Yoshi to let him ride him, due to Bowser's immense size. Bowser is outraged, but Mario tells him to ride on one of his Koopas or Goombas. Bowser makes Chef Pee Pee carry him on his back, much to the latter's ire, the result of which makes the latter go into a coma.
    • In the episode, "Shrek's Crappy Wish", when a wish Shrek made turns Mario into a donkey, Shrek tricks Mario into giving him a ride to change him back to normal, the result of which breaks Mario's neck.
  • Humiliation Conga: "Cody's Revenge!" is this for Junior.
  • Hypochondria: Each time Bowser watches a Charleyyy and Friends skit where Charleyyy catches a disease of any sort, he winds up believing he has the aforementioned disease.
  • Hypocritical Humor:
    • In "Jeffy's New Toy!", when Mario goes to Toys'R'Us to buy Jeffy a toy so he will shut up about seeing Ass Pounders 2, Jeffy tosses a toy of Bob the Minion on the floor. Mario scolds him for it, telling him he would have had to pay for the toy if it got broken. Mario then sees a toy of Baymax, decides he doesn't like it, and tosses it on the floor.
    • In "Bowser Junior's Imaginary Friend!", Chef Pee Pee comments that imaginary friends are for stupid people, only to reveal that he has an imaginary friend, too.
    • In "Jeffy's Teddy Bear!", Cody teases Jeffy for bringing Beary, Mario's teddy's bear to school, saying "Who brings a toy to school, you loser?". He says this as he is standing right next to his Ken doll.
    • In "Baby Jeffy!", when Baby Jeffy plays with a stacking rings toy, Brooklyn T. Guy reprimands him for putting the rings on in the wrong order, then tries to put a star-shaped block into a round hole.
    • In "Jeffy and Junior's Big Heist!", Jeffy tosses his ravioli, causing it to land on Bowser's signed underwear from Charleyyy. Upon seeing the stain, Jeffy says, "Those are some dirty underwear, Junior. They need to learn how to use the bathroom." This is coming from a teenage boy who still wears diapers.
    • Brooklyn Guy’s mother constantly complains about his son not visiting her, and then personally berating him in the same breath.
  • I Am Not Weasel:
    • Sonic the Hedgehog does not like being called a cat.
    • The crocodile from "Bowser Junior's Broccoli Problem!" doesn't like being called an alligator; even to the point where he tries to show Junior and his friends the difference between the two.
  • Identity Amnesia: In "Bowser Junior Gets His Nose Pierced!", Junior gets his nose pierced and starts thinking that he looks like a bull. The result is, well, he starts acting like a bull. He eventually snaps out of it after seeing Bowser's pierced nose.
  • Idiot Ball: Bowser Junior makes a lot of bad decisions mainly due to his ignorance, but they rarely ever work out. Even when the stunt is outright dangerous, such as farting into a gas pump, he doesn't consider the ramifications which, in this case, was an explosion.
    • Toad hogs the ball whenever he's on screen.
    • The Brooklyn Guy, rarely. In "Chef Pee Pee Quits! Part 2", he isn't a really good cook since while attempting to microwave a pizza, he pressed Frozen Vegetable, and even decided to boil the pizza after the former didn't work.
  • Idiot Houdini:
    • Bowser Junior doesn't learn from his mistakes, even if it involves a big outcome. He even lampshades it in "Bowser Junior's Piggy Bank!".
    • Jeffy qualifies even more. No matter how much he annoys Mario, he doesn't seem to learn anything from it, and he THROWS the blame on Mario, VERY indirectly, resulting in him getting tortured far beyond his original Butt-Monkey status, even resulting in his death in some cases. This has also been linked to Mario's numerous attempts to get rid of Jeffy failing every single time.
  • Ignorant About Fire: In the video "Bowser's House Fire!", Junior tries to imitate a stunt involving fire he saw on a Show Within a Show. When he is called from his bedroom to go get something to eat, he forgets to take the candle off the bed before leaving, and it results in the house going on fire.
  • Imaginary Friend: In "Bowser Junior's Imaginary Friend!", after finding out that his friends are too busy to play with him, Bowser Junior makes one up from his imagination and names him Gumbo, with the episode continuously switching between Junior's P.O.V. and reality. However, Junior later finds out that part of Gumbo's body disappears when he comes into contact with water, and when he tries to tell Chef Pee Pee, he accidentally sprays water all over Gumbo, disintegrating him. At the end of the episode, Chef Pee Pee is revealed to have an imaginary friend as well, named Lippy the Lion.
  • Ineffectual Sympathetic Villain: Mario. Though not necessarily a villain, he is stuck with Jeffy no matter what he tries to do, and even if he does bite back at Jeffy, his attempts to do so almost always fail. In the presence of Jeffy, Mario sometimes flanderizes into a Jerk with a Heart of Gold who tries to do the right thing but fails horribly, while Rosalina is more caring towards Jeffy than Mario and calls him out in the moment that he abuses Jeffy in any way. It doesn't help that most Jeffy episodes are more or less Mario torture porns, with "Jeffy's Bad Word!" and "Locked Out" being the worst offenders.
    • Some fans genuinely felt sorry for Mario after his appearance in "Jeffy's Bad Word!" due to him getting constantly harshly tortured far over his Butt-Monkey status, to the point where he ended up getting considered a registered sex offender and a felon, and had Rosalina tell him off. What Mario did to receive all of this was spank Jeffy for saying the word "faggot". The fact that everyone surrounding Mario was no more than idiotic and stupid contributed to the situation.
  • Inelegant Blubbering: Half of Rosalina's original dialogue is her screaming at the top of her lungs while sobbing so loudly and harshly that she nearly chokes in a few instances. All this because of either light pollution or the sun obscuring the stars. Nowadays, she doesn't do it that much.
  • Injured Limb Episode:
    • In "Bowser Junior's Broken Leg!", Junior breaks his leg after jumping from a jungle gym while racing against Joseph. Bowser has Chef Pee Pee give Junior whatever he wants for free until his leg heals, causing him to pretend his leg is still broken after it heals. Upon finding out about this, though, Chef Pee Pee breaks Junior's other leg.
    • In "Jeffy Breaks His Leg!", Jeffy gets his leg run over by Mario's car to get out of going to school. Mario has to take care of Jeffy for six to eight weeks while his leg heals. Jeffy torments Mario with ridiculous demands and continues to guilt-trip him by constantly blaming him for his broken leg. At the end of the episode, after Jeffy's leg heals, Jeffy stands under Mario's car to get his leg broken again.
  • Innocently Insensitive: In Mario and Bowser's Stupid and Crazy Adventures, after Mario rescues her, Peach tells Mario she loves him... like a brother. She doesn't mean it badly, but Mario doesn't take it very well.
  • Insane Troll Logic:
    • Toad's life runs on this.
      • During a Millionaire episode, he's asked how many wheels are on a unicycle. When he fails the question, he blames his logic on his dad being an alcoholic.
      Toad: Oh man. Geez, uh. Okay! So, uh, my dad was a truck driver. So, 'uni' means 'universe'. So, uh, oh geez. I guess eighteen, it's something like that, right?
      Brooklyn T. Guy: Eh-eighteen? Eh, are-are you sure that's your final answer? Hint-hint hint! Are-are you sure that's what you wanna go with?
      Toad: Yeah, I'm pretty sure, oh let me calculate. Um, you gotta be twenty one to drink too, so... yeah yeah yeah! It has to be eighteen, I know it!
      • Another example is in "Bowser Junior's Summer School 1". When Junior is panicking over his report card (he failed everything and got a B- in attendance), Toad reassures him that F isn't so bad because F also stands for Fantastic, Fabulous, Future, and Feliz Navidad. When Junior asks if he's sure, Toad tells him to think outside the box, duh!
    • Bowser Junior is completely convinced the Sun is a planet, much to Cody's irritation, and puts this up as a Running Gag in almost all of his recent appearances. Unlike Rosalina, who says the same thing but is clearly off her rocket, Junior makes logical arguments which are entirely wrong such as the Sun being round and therefore being a planet. He actually even died when trying to go to the Sun to prove it.
      • In "Bowser Junior Needs Glasses!" when Cody points out that if he looks at the Sun he'll go blind, Jr's counter-argument is that when he looks at the Earth he doesn't go blind, and that he's going to wave to the man on the Sun (and not the Moon) just to prove him wrong. He then goes legally blind, and claims Cody put a flashlight on the telescope that was so powerful it blinded him.
      • In "Cody's Sister!", he believes the Earth is flat, and claims that it is "how God sees the world". While Cody, of course, denies his theory, Joseph initially doesn't believe him either at first, but later falls for it after Junior says that they could agree that "a basketball is round, but a basketball court is flat".
    • When it comes to math, Jeffy believes that 2+2= Baby 2 because both 2s fall in love and make a baby 2 (and by the same logic, 4+4=Baby 4), 8-4=8 because the 4 is taken away, and 0+0=2 because there are two zeroes that don't love each other. He even curses his helmet, his pencil, his diaper, and various scientists while saying it is correct. And by the end of the video, "Jeffy's Law of Subtraction" is constructed based on his depictions.
    • Bowser Junior thinks that, because it's round, the Sun is a planet, and stars are pointy.
    • Much like Toad, Black Yoshi operates on this, even moreso after he Took a Level in Dumbass starting in 2017. Among other things, he believes that Black Friday means everything is free for African-Americans, and that it's illegal for the police to search one's socks. He also insists that since Mario can’t name a time he hasn’t paid him back (because it’s been every time), then he always pays him back whenever he gives him money, saying he pays him back with “friendships”.
    • In "Jeffy's Broken Toy", Mr. Goodman claims that since not everything said on TV is true, he doesn't owe Mario his money back for the broken toy.
    • In “Jeffy’s Green Bean” allergy, Marvin tries to find other vegetables for Jeffy to eat since green beans gives him a severe allergic reaction (which he did to himself using a baseball bat). When Brooklyn Guy suggests feeding him fruit, Marvin refuses to do so because fruits are “too yummy.” Marvin doesn’t fully explain his point, since he interrupts himself mere seconds later to change the subject.
  • Insufferable Imbecile: Several characters can come to mind such as Bowser Junior, Jeffy who can be a sociopathic character, Rosalina, Black Yoshi, Bowser who is a lazy [1], and more characters such as Toad.
  • Interspecies Romance:
    • In "Mario's Wig", Princess Peach hooks up with Sonic the Hedgehog, much to Mario's annoyance.
    • In "Black Yoshi's Girlfriend Problem!", after Delilah breaks up with Black Yoshi, she hooks up with Popeye.
  • Iris Out: "Black Yoshi's Girlfriend Problem!" ends with this.
  • Irony: In "Chef Pee Pee Quits Part 2", Bowser and Bowser Jr. fire Craig because of his terrible cooking. The ironic part of this is that Chef Pee Pee in the majority of the videos, cooks much worse than Craig, but they never think to fire him, just complain to him.
  • It's a Wonderful Plot: In "Bowser Junior's Eleventh Birthday!", when no one shows up to Junior's birthday party at Chuck E. Cheese's, Junior wishes he were never born. He gets knocked out playing skee-ball and has a dream where God shows him what life would be like if he were never born:
    • Bowser's old house never burned down due to the events of "Bowser's House Fire!" never happening.
    • Bowser was able to watch TV non-stop due to Junior never interrupting him, and ended up dying as a result of doing nothing else.
    • Chef Pee Pee became a professional chef who owns a five-star restaurant called "A Taste of Pee Pee" due to not having to babysit Junior.
    • Brooklyn T. Guy became homeless due to not having any problems to solve, courtesy of Junior, and nobody wanting to hire him.
    • Cody became interested in dating girls due to never meeting Junior and finding the Ken doll when the two went to Toys R Us together.
    • Joseph starved to death due to not being able to visit Junior at his house and eat his food.
  • Jerkass: Several characters come across as such.
    • Bowser, who abuses his own son for pleasure and treats his personal chef like dirt.
    • Junior is also one as when he's playing with Joseph and Cody, he'll throw a fit if he doesn't get his way.
    • Chef Pee Pee can sometimes be downright rude towards Junior and his friends, though Junior himself also qualifies as a Jerkass, and usually starts it.
    • Brooklyn T. Guy can be this, as well. One example is when he complains to Mario about his ex-wife snoop husband named "Dave", and Mario briefly apologizes as a result. He also sometimes refuses to help Mario with his problem of the week.
    • Mario became one after Jeffy was dumped on his doorstep and he reluctantly became his Parental Substitute, especially in the Jeffy episodes where he is pushed to an Ineffectual Sympathetic Villain who tries to get rid of Jeffy but fails every time. Granted Jeffy's obnoxious behavior can usually get on most peoples' nerves, but still. Fortunately, he gets better after "Jeffy's Parents!"
    • Peach is also a big one for divorcing Mario just because he's bald.
    • Jeffy. He always tortures Mario, throwing a fit whenever he wants stuff, and since "Smart Jeffy" has become very diligent and foul-mouthed, almost always asking "ARE YOU FUCKING HIGH?!" whenever his hopes are thwarted. He has even conned Mario into giving him money. Twice.
    • Mr. Goodman takes this to a whole new level after Flanderization into a Corrupt Corporate Executive where he's always extorted Mario with the excuse of collecting "house payments" despite already being filthy rich and has even cheated Mario out of his money several times. Not only that, he's gone as far as to threaten mutilation so extreme, it would make even the most hardened serial killer cringe; namely, he's threatened to rip off Mario's testicles with his mouth, as well as give him such a hard purple nurple that he would rip his nipple off and eat it. In fact, the character Q&A videos on Lance's channel reveal he has done this to many, many people, as he has seems to have a cannibalism fetish. Worse still is that Goodman rarely, if ever, receives any comeuppance for his actions, mainly because the police are extremely corrupt and take bribes like candy.
    • Nancy from "Jeffy's Parents!" is arguably the worst one of them all. She's an alcoholic chain-smoking prostitute who abuses Jeffy, both physically and emotionally and then abandoned him. Then after a year, she tries to take Jeffy's inheritance away from him.
  • Just One Extra Ticket: "2 Tickets" deals with Junior having to decide on whether to give Joseph or Cody his extra ticket to Punch in the Face-a-thon. He winds up having to Take a Third Option and give it to Bowser since he forgot it was Father’s Day and did not get him a present.
  • Kids Hate Vegetables:
  • Kill It with Water: What ultimately disintegrates Gumbo from existence in "Bowser Junior's Imaginary Friend!", though it was just an accident caused by Chef Pee Pee.
  • Knight of Cerebus:
    • David Winkle, the perverted child molester. Though he does have his moments of Laughably Evil.
    • Nancy, Jeffy's biological mother, is played seriously in her debut episode "Jeffy's Parents!", unlike several other antagonists. She is an alcoholic child abuser who beats Jeffy, and purposefully abandons him.
  • Know-Nothing Know-It-All:
    • Junior, in regards to his theory that the Sun is a planet.
    • Jeffy in "Jeffy's Homework!" claims 8 minus 4 to be eight because the four is taken away, and even goes into a profanity-loaded rant while doing so.
    • Toad has some moments, as does Chris the Cucumber.
  • Large Ham: Bowser, especially in his Bowser Juice commercial. There's also Jackie Chu and, to a lesser extent, Billy the Puppet ("AIIIIDDSSSS!!!!!").
  • Lampshade Hanging: Bowser notes that Charleyyy is jumping into a pool that looks exactly like his own pool. Nothing else is said about it.
  • Laser-Guided Karma:
    • Junior used to be a really big one.
      • For instance, in "Bowser Junior's Summer School 4", Junior fakes being sick to skip school. Their teacher Jackie Chu decides to give out cupcakes and cookies for all the class, along with no homework that night. While Junior gets a beating when he's caught playing Minecraft when he should have been in bed.
      • "Junior's Karma!" has an entire plotline running on this trope; thanks to his bad deeds, Junior ends up getting multiple punishments, many of which are undoed when he tries to complement Cody at the end.
    • For a while, Jeffy has also gotten comeuppance following the bad reception of "Locked Out", like for example Mario giving him a timeout in "Turkey Tyranny!" because it's "what the fans want", or Mario beating him up at the end of "First Day Of School!".
  • Leitmotif:
    • Italian music can be heard whenever Chef Pee Pee appears.
    • Bowser has a dramatic violin tune.
    • Junior has a children's-style cheerful theme.
    • Black Yoshi's is rap music.
    • Jeffy has a goofy piano theme. This would occasionally play whenever Jeffy would do something Mario and Rosalina don't like, such as ruining their adult-time or pooping in the sink.
    • Mario and his friends have a classical jazz theme.
    • Hansel, the hobo from "Mario's Hobo Problem!" has a bluegrass theme for his drunken shenanigans.
  • Lemonade Stand Plot: In "Bowser Junior's Lemonade Stand!", Junior opens his own lemonade stand so he can raise $300.00 to buy the Big Jumbo Box of Toys. However, Cody also starts his own pink lemonade stand to raise money for an operation which is revealed in the end to be for a penis enlargement, which becomes more popular than Junior's lemonade stand. The two get into a competition with each other, which culminates in Junior hiring the Loan Dolphin to destroy Cody's stand. When the Loan Dolphin refuses, Junior does it himself. The Loan Dolphin calls Officer Goodman, who tells Junior that it's illegal to destroy someone's lemonade stand, and tells Junior that he is no longer allowed to sell lemonade or lemons in the state of Florida.
  • Lethally Stupid:
    • Jeffy would be the best example of this. Specifically, he put Mario in danger of getting his ballsack bitten off after breaking a Nintendo Switch, and even managed to throw a taco bomb on the couch, resulting in the deaths of himself, Mario and Cody.
    • Junior also qualifies at times; for one, he burned down his own house and school, and poisoned Chef Pee Pee as part of an April Fools' prank with Toad.
  • Lightning Can Do Anything: "SuperPowers!" has Junior, Joseph and Cody getting struck by lightning and gaining superpowers as a result.
  • Loan Shark: A dolphin is one of these, being called a Loan Dolphin.
  • Locked in a Room: In "The Elevator!", Junior, Joseph, and Cody get stuck in an elevator on their way to a meet and greet hosted by Doofy the Dragon.
  • Locked in the Bathroom: In "Shrek's Bath Problem!", Mario is trapped in the bathroom with Shrek, who called him over in the first place because he pooped in the bathtub. The Brooklyn Guy shows up as a locksmith, but the lock is too complicated for him to figure out, so Toad slips a mini mushroom under the door, causing Mario to shrink and get out from under the door. At the end of the episode, Shrek opens the door easily by jiggling the doorknob.
  • Love Epiphany: In "Mario's Valentine's Day Problem!", he starts off the day with Rosalina as intended, but then the girl he's always loved, Peach, shows up and wants him back. He has Rosalina hide (using various excuses) and wait for him while he tries to have a (very brief) Valentine's Day with Peach. After only a few minutes of putting up with her, it occurs to Mario that Peach really isn't everything he wanted and she doesn't appreciate anything he does, and that he has a good thing with Rosalina who seems to have a good time with him no matter what they do. He kicks Peach out, apologizes to Rosalina (who had no idea that any of this happened), and proceeds to have a small Valentine's Day dinner where he sits there and appreciates Rosalina's quirky personality.
    Rosalina: What's going on?
    Mario: Well, you see... um... I'm just a big idiot and I'm stupid and... I didn't realize that you were the most amazing girl in the world, and I would be stupid to lose you and, that's why I got you this card. (hands her a Star Wars card)
    A few moments later
    Mario: You're just, you're the most amazing girl in the world baby, and... I don't ever want to lose you!
  • Love Potion: In "The Love Potion!", Cody invents a love serum for Junior to inject into Britknee, the newest student, to get her to fall in love with him. However, there are two catches; once injected, she falls in love with the first person she sees (who happens to be Jeffy), and after a few hours, the serum turns her into a dragon.
  • The Magic Touch: In "Bowser Junior's Curse!", Junior refuses to eat his corn dogs and tosses them out the window, and as a result, the Corn Dog God curses him with the corn dog curse, wherein everything he touches turns into a corn dog.
  • Minor Flaw, Major Breakup: In "Jeffy's Christmas Gift!", Rosalina threatens to leave Mario if he doesn't buy a Turboman doll for Christmas, since she believes it's "not taking care of his own child."
  • Mistaken for an Imposter: In "Jeffy's Tantrum!", Mario refuses to buy Jeffy a Spongebob Squarepants game on the App Store with his credit card number, leaving Jeffy to run away. The doorbell then rings, and Mario comes across who appears to be Jeffy wearing Groucho Marx glasses, asking for his credit card number. Mario thinks it really is Jeffy, so he refuses to tell him his credit card number, and tells him he's not fooled by his disguise. The Groucho Marx Jeffy tells Mario he doesn't know what he's talking about, and the real Jeffy shows up, asking Mario who the guy who looks like him is.
  • Mistaken for Cheating: The ending of "Jeffy's Cellphone!" has Jeffy calling a prostitute, telling her his name is Mario, and asking her to touch his "pee-pee" for five dollars. The prostitute shows up a few seconds later and tells Mario they talked on the phone, confusing Mario and Rosalina. After the prostitute tells Mario she's going to touch his "pee-pee" for five dollars, an angry Rosalina thinks he's cheating on her and beats Mario up.
    • Another one happens in “Jeffy’s Online School!”, when Rosalina catches Mario watching an elderly cam-stripper roleplaying as a teacher. Rosalina is completely stuck with the idea that Mario is cheating on her, and constantly berates Mario for it throughout the video. It takes Chef Pee Pee watching the stripper herself and Jackie Chu apologizing for giving Mario the wrong link to convince Rosalina otherwise.
  • Mistaken for Racist: The plot of "Cody's Bad Word!" has Cody saying the word "inwards" while he, Junior and Joseph are playing Jenga, which makes Junior and especially Joseph believe that he said something else and that he's racist. And it gets even worse when Cody does some stuff that still make the two think he's racist.
  • Mood Whiplash:
    • In "Cody's Revenge!", Cody tells Junior to say that the Sun is a star and not a planet, in order for him to stop blackmailing him. Just when it looks like Junior is starting to admit that it's actually a star, he suddenly shouts that it's a planet and snaps due to all the misery Cody did to him.
    • In "Bowser Junior's Piggy Bank!", when Junior goes to admit that he broke Bowser's piggy bank:
      Bowser Junior: Well, wasn't my dad's piggy bank that turned into a real pig.
      Brooklyn T. Guy: Oh, what was it?
      Bowser Junior: was Cody's mom.
  • Mourning an Object: In "Broken", Cody is distraught over the "death" of his Ken doll after it fell from Junior's house's two story stairway and broke in half.
    Cody: (sobs) IN HALF!!
  • Movie-Theater Episode:
    • In "Bowser Goes to the Movies!", Chef Pee Pee takes Bowser to the movie theater to see Charleyyy and Friends: The Movie. Bowser is very disruptive in the movie theater; talking throughout the movie, tossing his food around, and blaming his actions on the other customers.
    • In "Bowser Junior Sneaks Into A Movie!", Junior, Joseph, and Cody see a trailer for an R-rated horror movie called Hide and Seek: The Movie. When Chef Pee Pee refuses to let them see it, they decide to sneak into the movie theater themselves. Along the way, Cody sees Happy Pony 4.
    • In "Jeffy Sneaks Out!", Bowser Junior asks Jeffy if he can go to the movies with him. Jeffy asks Mario for his permission, and when Mario tells him "Not today", Jeffy has a swearing fit that results in Mario grounding him for two weeks. Jeffy creates a clone of himself out of his Play-Doh (It Makes Sense in Context) to take his place while he and Junior sneak out to go to the movie theater. While Play-Doh Jeffy causes havoc at Mario's house, Junior and Jeffy see Hot Dog Man at the movie theater.
    • In "The Movie Date!", Brooklyn T. Guy knocks Mr. Goodman unconscious and borrows his lamborghini long enough to pass himself off as a rich man and go on a movie date with Sparkle. While in the movie theater, Brooklyn and Sparkle watch a much more mature version of Incredibles 2.
  • Muppet: Most of the non-plush characters.
  • My Little Panzer:
    • In "Bowser Junior Goes to Disney World", Doofy advertises Doofy-O's cereal, with a knife as the prize that wins them a trip to Disney World inside specially marked boxes.
    • In "Bowser Junior's 7th Birthday!" Chef Pee Pee buys Junior a "Can You Kill Doofy?" party game, complete with a real knife to pin on Doofy.
    • In "Bowser's Driver's License", during a Doofy the Dragon-themed McDonald's commercial, as if the burger with nails, broken glass, and a mouse trap wasn't bad enough, Doofy also advertises nine-millimeter guns as Happy Meal toys.
    • In "Bowser Junior's Game Night 3", when Junior, Joseph, Cody, and Jeffy play "What's in Ned's Head?", Jeffy manages to find a real loaded gun in Ned's head. Junior and Cody even question why someone would put it in a children's board game.
  • Names to Run Away from Really Fast: From "The Secret Door!", we have Does Bad Things Guy, a relative of Brooklyn T. Guy.
    • This also gets played with in the form of an inversion; Does Good Things Guy. He's also a relative of Brooklyn T. Guy, albeit one that doesn't resemble him.
  • Nature Tinkling: The plot of "Jeffy's New Dad" is kicked off when Mario pees in a bush at the park. Patrick sees him and he gets arrested for public urination and exposure, as well as being registered as a sex offender.
  • N-Word Privileges: In "Bowser Junior's YouTube Channel!", Junior gets punched in the eye by one black man, punched in the other eye by another in his closet, and then beaten into a wheelchair by Chef Pee Pee all because of this. He states he heard the word in a rap song and just wanted to use it, not realizing the implications behind saying it to strangers and people who dislike you.
  • Nerds Love Tough Schoolwork:
    • Cody gets super excited whenever Jackie Chu assigns a super hard homework assignment.
  • Never My Fault:
    • Shrek blames Mario for his own faults, such as clogging up the toilet and using all the toilet paper.
    • In "Bowser's Goldfish!", after Toad flushes Bowser's pet goldfish, Charleyyy Jr., down the toilet, and CJ doesn't come back up, Toad blames Junior for not having a brand new toilet with a fish-catching mechanism.
    • In "Jeffy's Bedtime!", Jeffy blames his pooping his pants on the (nonexistent) monster who lives under his bed.
    • In "Bowser Junior's Nintendo 3DS", Junior blames his broken 2DS on Brooklyn T. Guy, despite Junior breaking it in the first place.
    • In "Jeffy Sleepwalks!", Jeffy blames his mess in the kitchen and trail of Froot Loops leading to his bed on Mario of all people. He is also completely convinced that he did not mess up the living room. He is technically telling the truth as he admits he never was sleepwalking, he was just trying to see all of the things he could do with his eyes closed.
    • In "Jeffy Plays Minecraft!", Mario blames Minecraft and a YouTube video for Jeffy's destructive behaviour, when in fact he gave Jeffy a laptop to keep him occupied and didn't even want to parent him. Jeffy and even Goodman, of all people, point out his faults to him.
  • Never Trust a Title: Many videos have misleading titles, especially the ones that mention Jeffy, since the videos themselves usually have little to nothing to do with him. Examples are Jeffy's Online School, Chef Jeffy, Jeffy Skips School, and Jeffy Plays Baseball.
  • New Job as the Plot Demands: Pretty much every scene involving the Brooklyn Guy who always has a new job every episode. Amongst a few have been electrician, lizard wrestler, police officer, driving instructor, firefighter, construction worker, host of Who Wants to Be a Millionaire?, military sergeant, fly killer, and pilot.
  • Nice Job Breaking It, Hero:
    • "Bowser Junior's Broccoli Problem!"; a simple situation where Junior has to eat broccoli escalates into a sewer crocodile breaking into the apartment, all because Junior flushed his broccoli down the toilet.
    • Toad literally breaks Tony and Chad's egg in "Replacement Egg". He tries getting another egg out from the fridge, only to break it as well. Guess what he does next.
    • Chef Pee Pee in Bowser Junior's Summer School. Not only does he set the plot in motion by telling Bowser his son scribbled on his report card, but he himself ends up suffering as he is forced to drive Junior to school every day and make him French fries for breakfast at one point, not to mention getting mad at Junior after letting him pour the milk when making cereal.
    • In "The President's Chef!", Junior steals the Declaration of Independence. Then he gets it wet and rips it.
    • In "The Ouija Board!", Junior and Joseph end up insulting the Ouija demons, and they get back at the trio by possessing Cody's Ken toy.
    • In "Bowser Junior's Clown Car!", Junior gets hold of Bowser's old clown car, despite Bowser warning him not to play with it, and accidentally shatters the table with a cannonball. His attempts to fix it only make the problem worse — it doesn't help that he actually believes he fixed the table — and at the end, he is sent to military school.
  • Nice, Mean, and In-Between:
    • Respectively, Cody is the nice one for being smart, sane and calm, the mean one is downplayed with Junior since he can sometimes throw a fit when he plays with Joseph and Cody along with being cruel to Cody at times, and Joseph is in-between due to sometimes being the sanest at times and having an arrogant attitude along with being rude to Cody by calling him weird and making fun of him with Junior.
    • The Bowser Junior, Bowser and Chef Pee Pee trio follow this trope too, but this time, Junior's role is different; Junior is the nice one who likes to play with toys and annoys Bowser and Chef Pee Pee, where it's Bowser who's the mean one for yelling at Chef Pee Pee nonstop and causing additional chores for him, beating Junior up and being a trademark Jerkass while Chef Pee Pee mediates in-between where he's smarter than Bowser and Junior and being much saner than them, but can sometimes act grumpy towards them when they annoy him, even though Bowser and Junior both start it.
    • The Rosalina, Jeffy, and Mario trio also follow this trope; Rosalina is the nice one for treating Jeffy with respect and sticking up for him if Mario abuses him in any way, Jeffy is the mean one for throwing temper tantrums and generally annoying Mario, and Mario is the in-between one for being the Straight Man who disciplines Jeffy when he misbehaves.
    • By dividing the new main six kid characters: Cody and Timmy are the nice ones seeing as they are both intelligent, have common sense and don't mistreat anyone, especially the latter. Junior and Joseph are the mean ones as they are rude to Cody and sometimes Timmy and like to cause trouble, and Jeffy and Penelope are in-between as they have their fair share of rudeness, but not harsh towards Cody and Timmy as much as Joseph and Junior are.
  • Nightmare Sequence: Junior has one in "Bowser Junior's Flu Shot!".
  • Nighttime Bathroom Phobia: In the music video "I Gotta Pee", Toad has a Potty Emergency at night and fears that a ghost might come for him. Ray Cheesy has to go too and accompanies him to the bathroom, but Toad takes a long time, much to Ray's dismay.
  • Ninja Pirate Zombie Robot: In "Cody's Missing!", Cody becomes "Metal Baby Cat Cody" (which consists of him wearing a cat suit and tin foil pants, and sucking on a pacifier) in response to Nintendo using Metal, Baby, and Cat versions of existing characters as filler for its Mario sports games instead of him. He later creates his own game, Cody!, wherein Metal Baby Cat Cody is one of the many playable variations of him.
  • No Animals Were Harmed:
    • In "Bowser's Goldfish!", Logan did use a real goldfish in almost every scene, but used editing to simulate it flushing down the toilet. He ends the episode showing both fish, saying they weren't harmed, and displaying the typical image.
    • In "Jeffy's Pet!", Logan used a real hamster for Jeffy's pet hamster, Melvin/Pee Pee Suck 2. In The Stinger, he revealed that he used a stuffed animal in place of the hamster for the scene where Junior tossed Melvin/Pee Pee Suck 2 down the stairs.
  • No-Dialogue Episode: Most of the first half of "Bowser Junior's Nerf War!" is this.
  • No Fourth Wall: The characters seem to be aware that they are in YouTube videos, as shown in "Cool Cody!" and "Evil Chef Pee Pee!". This also became a Running Gag for a brief period in late 2016, following the move into the new house.
  • No Ending:
    • You would expect "Chef Poo Poo's Kitchen Disaster!" to end with the characters cleaning up the mess, but instead, we have Bowser's mom appreciating the mess, Brooklyn T. Guy arriving and part-stripping himself, and Bowser's mom telling everyone if they can take her clothes off. And the mess still hasn't been cleaned up yet.
    • "Cody's Sister!" ends with Junior and Joseph angrily suggesting to end the video after finding out that Cody's sister Katy already has a girlfriend, a "limited edition, never been open, 50th anniversary, summertime Barbie". The video in fact never gets to the point where Katy eventually leaves for Wisconsin.
    • "The Cat in the Hat" ends with the titular character's head exploding from trying to think of a rhyme for "orange", and Junior wondering who's going to clean up the mess the Cat made. Cody points out to Junior that the Cat usually cleans up his messes after he makes them, but since the Cat's dead, he can't do that. He then asks Junior when he's going to military school, and the episode promptly ends.
    • "Jeffy's Wifi Problem!" is more or less a downplayed example, as Jeffy never gets the WiFi password yet not only does he use the neighbour's WiFi anyway, thanks to Junior, but he gets away with all he has done so far.
  • No-Holds-Barred Beatdown: Principal Steinbeck beats the heck out of Toad all over a paper ball. On a related additional note, Toad screams as Steinbeck punches and even elbow drops Toad.
  • No Name Given: The Brooklyn Guy, who claims his name really isn't important. In "Bowser Junior Loses Thomas!", he works as a Toys R Us employee. When Chef Pee Pee asks him where his name tag is, he states that he doesn't have a name tag because he doesn't have a name. As of "Bowser Junior Goes To Military School! Part 1" and "Jeffy's Stupid Home Video!", he now goes by Brooklyn T. Guy.
  • Non Sequitur: Part of Junior's rabies symptoms in "Bowser Junior Gets Rabies!":
    "I couldn't pick my nose if I wanted to—my arms are too short..."
    "Guys! Guys. They don't sell--they don't sell pancakes at Waffle House..."
    "I'm kicking my ass! DO YOU MIND?!"
  • "No Peeking!" Request: In "The Elevator!", Bowser Jr., Joseph, and Cody are trapped inside an elevator when Junior suddenly has to pee. He decides to use an empty cup that was left on the floor and tells the others not to look at him.
  • Nothing Left to Do but Die: Junior hanged himself upon getting a 10-minute "staying in the corner" punishment.
    • In "Bowser Junior Loses Thomas!", he resorts to waiting for a train to run him over after losing all hopes of finding his Thomas toy...which was behind the couch the whole time.

  • Obfuscating Disability:
    • In "Bowser Junior's Broken Leg!", Bowser Junior breaks his leg and spends three weeks in bed waiting for it to heal, with Chef Pee Pee bringing him whatever he wants. After it heals, he pretends his leg is still broken to continue to get free stuff from Chef Pee Pee, despite a warning not to from Brooklyn T. Guy. This comes back to bite him two weeks later, when Doofy the Dragon hosts a meet and greet at the mall, which Junior wants to go to. After Junior admits to Chef Pee Pee that he's been lying about his leg for the last two weeks, Chef Pee Pee beats him up, breaking his other leg.
    • In "Jeffy Plays Baseball!", Goodman fakes Laser-Guided Amnesia after getting knocked out by Jeffy with a baseball bat. He also later reveals that he faked paralysis as retaliation for his windshield getting broken.
  • Obvious Stunt Double: If you look closely on the stunt Bowser in "Bowser Loses A Tooth!", you'll see that it is shaped more like the old Bowser plush of which Logan lost, and the skin surrounding Bowser's mouth is lighter than that of the main Bowser plush.
  • Offscreen Teleportation: In "Cody The Magician!", Joseph shows up at Junior's door, and the two are surprised Cody isn't there. When Junior asks where Cody is, Joseph admits Cody just appears when he knocks on Junior's door. The two sit there confused, and don't bring it up when Cody appears moments later.
  • Off-the-Shelf FX: Some of the characters, notably Chef Pee-Pee, Brooklyn T. Guy and Doofy the Dragon, are repurposed Melissa and Doug puppets. In addition, some real life toys are used as items the characters play with, like Jeffy's cat piano, which is a Target-branded toy.
  • Off with His Head!:
  • Oh, Crap!:
    • Mass "Oh, Crap!": Mario, Junior, Brooklyn T. Guy, and Chef Pee Pee at the end of "The Golden Egg!", after realizing that Jeffy not only found the golden egg, but also wished for it, essentially making its one wish useless. As a result, they all beat him up to death.
    • In "Bowser Junior's Big Mess!", Toad using his Insane Troll Logic tricks Junior into thinking the Diet Coke and Mentos trick wouldn't make a mess. Junior freaks out when he realizes what he has done.
    • Mario, Chef Pee Pee and Brooklyn T. Guy in "Mario's Hobo Problem!" after seeing how big of a mess Shrek made with the toilet, to the point where their disgust and shock leaves them literally speechless. Averted with Hansel and, well, Shrek himself, as they don't seem to react in any manner.
    • Mario's reaction in "Where's Jeffy?" to Rosalina telling him where she put her necklace: around Jeffy's neck. And this is after he left him alone at the park...
  • One-Shot Character: A large range of one shot characters is associated with the series; Stacy and her unnamed sister, the Alternate Dimension counterparts from Mario and Luigi's Stupid and Dumb Adventures (excluding Alternate Mama Luigi), SpongeBob, Dora, Crusty, Stinky, Remy, Gumbo, Katy, D-Money the boxer, Feebee, the list goes on.
  • One-Steve Limit: There are two characters named "D-Money" in the series; a gangster kid who is one of Bowser Junior's classmates in the first gradenote , and a boxer who is Rosalina's ex-boyfriend. Word of God has confirmed that the gangster kid is the boxer's son.
  • Only in Florida: The series takes place in Florida.
  • Only Sane Man:
    • Mario is just about one of the only main normal people on the show.
    • Chef Pee Pee also qualifies, in comparison to Bowser and Junior.
    • Brooklyn T. Guy is one of the few puppets who's actually not a moron.
    • Joseph is the only kid who isn't a total moron like Junior or a pervert like Toad and Cody. However, Cody is the wisest and most level-headed compared to the two.
    • Female example: Emily Coleman (Patrick's sister) is one of the few of Bowser Junior's classmates in the Bowser Junior's 1st Grade! series who has some common sense and maturity.
    • Another female example is Penelope, Brooklyn T. Guy's daughter, who is one of the few saner and smarter students in her class alongside Cody.
  • The Ophelia: Rosalina is not what one would call sane, but she's still treated as being adorable or cute by Mario even if she does get annoying.
  • Original Generation: The channel mostly uses Mario series plushies, and sometimes other Nintendo characters, but there are many original puppets created by other companies, including Chef Pee Pee, Brooklyn Guy, Mr. Goodman, Jackie Chu, Jeffy, Judith and Tyrone, Doofy, Craig the Devil, Patrick, Karen, Feebee, Penelope, Johnathon, Cameel Habeeb Habob, and Richard.
  • Overly-Long Gag: Brooklyn T. Guy making fat jokes out of his ex-wife becomes this on a few occasions, notably in "Jeffy Gets Glasses!".
  • Parental Abandonment:
    • Bowser may be in the other room, but he rarely does anything to help Junior if it doesn't directly help himself as well. He beats his child for screwing up and screams at Chef PeePee, but beyond that he refuses to help his kid with homework, refuses to get his kid food, refuses to be around his son in general due to 'not liking him', and even admitted at one point he didn't even really want him.
    • In "Mario the Babysitter!", Jeffy's real parents left Jeffy for Mario to take care of, and have yet to return for him. Mario, who has since become Jeffy's Parental Substitute, has also tried to do this to him multiple times, and failed.
  • Parental Substitute:
    • Because Bowser is usually in the other room watching Charleyyy and Friends, Chef Pee Pee is usually the one watching his son, Junior.
    • Mario has become this to Jeffy in virtually all videos where they appear together, because Jeffy's real parents were too annoyed by him and didn't want to deal with him any further.
  • Perpetual Expression: Just about every plush and puppet character in the show has the same expression, with the exception of custom thumbnails, the second half of "Bowser Junior's All Nighter!", "Bowser Junior's Nerf War!", and a certain point in "Where's Jeffy?". More recently following the switch to Human Puppets, this trope has been subverted more often, in one case having black fleece eyebrows sewn on the Brooklyn T. Guy puppet for scenes where he would be mad.
  • Perpetual Smiler: Mr. Winkle is always cheerful and authentic about the situation, even when he's about to get arrested by Goodman.
  • Pilot: "The Bird" is a pilot for Black Yoshi and the Birds.
    • "Bowser Junior's Homework" ended up leading to Bowser Junior's Summer School.
    • "Bowser Junior's Clown Car!" and "Cody's Revenge!" serve as the pilots for the Bowser Junior Goes To Military School! mini-series.
  • Pink Girl, Blue Boy:
    • In "Cody's Sister!", Cody's twin sister, Katy wears a pink shirt and hat, while her brother wears a blue shirt and hat.
    • Jeffy's sister, Feebee, wears a pink shirt and helmet, while Jeffy wears a blue helmet and a yellow shirt.
  • Please Wake Up: Junior in "The Magical Button!", upon finding out that Chef Pee Pee and Bowser are dead due to him pressing the titular button for wishes.
  • Political Overcorrectness: This has been Joseph’s main character trait since the videos switched to human puppets, most infamously in “Cody’s Bad Word!”
  • Potty Emergency:
    • In "Bowser Junior's Punishment!", Charleyyy has one in an episode of Charleyyy and Friends that Bowser is watching. Unfortunately, someone (presumably Shrek) is already in the bathroom. Charleyyy then improvises by using the litter box.
    Charleyyy: If cats can do it, I can, too!
    • Bowser Junior has one in "The Elevator!", which sets the episode's main plot in motion. He eventually relieves himself in a cup he found on the floor, much to the disgust of Joseph and Cody. And he nearly gets close to drinking it.
    • Junior has one in "Life Is Ruff!", when he is in Chompy's body. He tries to tell Chef Pee Pee to let him out, but Chef Pee Pee is unable to understand him. Chef Pee Pee ends up scaring him and making him pee on the floor.
    • Jeffy has one at the beginning of "Jeffy Gets Stung By A Bee!", and acts like a dog so he can get Chef Pee Pee to take him outside to poop, which sets the episode's plot in motion.
  • Potty Failure: Jeffy tends to soil his pants all the time, and because his diaper is taped over his pants, it stays clean while his pants get dirty. "Jeffy Gets Potty Trained!" focuses on Mario and Rosalina's unsuccessful attempts to potty-train him to prevent future accidents.
  • Prison Rape:
    • Bubbles in Season 1 and 2 of Mario and Luigi's Stupid and Dumb Adventures (in the first season he looks like Wario, in the second one he is a black dude) to Mario.
      • In the first season, Mama Luigi enjoys getting raped by Bubbles.
    • Bubbles returns in Bowser Junior's Summer School, where he rapes Pixie Goblin/Toon Link twice. He also gets mentioned frequently by Officer Goodman.
  • The Problem with Licensed Games: In-universe example with Charleyyy and Friends: The Video Game, from the episode, "Bowser's Video Game". The game's atmosphere and humor are both very accurate to the show it's based on. However, despite being advertised as an M rated game, it lacks a lot of the advertised adult content. The game also suffers from unresponsive controls, Charleyyy loses health from such things as not having any mail in his mailbox and not having any gas in his car, there are tons of loading screens, and as proven by Bowser Junior, the game can be beaten in ten minutes, complete with an A Winner Is You ending.
  • Product Placement: Various. Apple, Sony, Microsoft, Chevrolet, Chips Ahoy, Kool-Aid, Thomas & Friends, McDonald's, Minecraft, Crayola, Oreo, Zebra Cakes, Buffalo Wild Wings, Monster Energy, 5-Hour Energy, Red Bull, A&W, Hershey's, Campbell's, Coca-Cola, Diet Coke, Mentos, Kraft, Rockin' Rider Legend, Ice Age: The Meltdown, Barbie, Five Nights at Freddy's, the list goes on and on and on and on and on and on and on...
  • Punctuated! For! Emphasis!: If every video title from 2014 containing an exclamation point hasn't already given this trope away.
  • Put on a Bus: Brooklyn T. Guy since "Stuck in a Tree", which was his first appearance, until he returned at the end of "Bowser Junior's Summer School 5".
  • Readings Are Off the Scale: In Shrek's diet, Shrek's blood is tested after he has a heart attack. The doctor notes his blood is cheese because he eats way too much cheesecake, and that he has so much diabetes that he has built an immunity to the diabetes because of the massive amount of diabetes he has.
  • Really 700 Years Old: Bowser is apparently 312.
  • Red Sock Ruins the Laundry: In "Bowser Junior's Pink Bib!", Junior stains Chef Pee Pee's red jacket when he tosses Cody's LEGO airplane into the mac and cheese Chef Pee Pee made. Afterwards, Cody sneezes on Junior's bib, so Junior has Chef Pee Pee wash it for him. Because Chef Pee Pee washed both his jacket and Junior's bib at the same time, Junior's bib is turned pink. When Joseph and Cody see the pink bib, they tease Junior.
  • The Remake: "The Koopalings!" is a remake of "The Koopa Kids!", only subverted since it is far from a remake. It doesn't feature Shelia Perkins, the plot is completely different, the video features Joseph, Cody, Screwball, Hansel from "Mario's Hobo Problem!", and a new female character referred to as Crystal, five people who didn't appear in the original video, and the Koopalings are known by their canon names.
  • Repetitive Name: Jeffy's full name is "Jeffy Jeffy". Really.
  • Reset Button: In "The Past Machine!", after summoning two meteors, believing that they will only kill a T-Rex that he brought into the present, Junior uses the titular machine to reset not just the video, but the entire Universe itself. By bringing back the BIG BANG.
  • Retcon:
    • Unhappy with the original Koopalings video and unable to film the sequel since he is no longer at his parents' home, Logan decided to completely remake the Koopalings episode, going through a completely different plot and keeping their personalities, but retaining their Nintendo canon names rather than the names he made up for them in the original Koopaling episode. As such, the original Koopalings video, including Bowser's ex-wife Sheila Perkins, is now non-canon.
    • Following Nintendo's C&D, a few Nintendo-based characters were remade entirely based on this manner; for example, Black Yoshi became "Ya Boy Duggie", a dinosaur who is recruited to help Booger, his cousin and Jeffy's pet, only to ultimately become just as addicted to Kool-Aid, KFC and Call of Duty as Black Yoshi was.
  • Revenge: "Cody's Revenge!" has Cody blackmailing Junior with a picture of a broken bowl of Raisin Bran he took on his phone as revenge for all the things he did to him.
  • Rhymes on a Dime: The Cat in the Hat from the episode of the same name. He explains to Junior that it's a pain for him to always rhyme, but he gets paid for every rhyme he makes. At the end of the episode, his head explodes when he tries to think of a rhyme for "Orange".
  • Ripped from the Headlines: The storyline of "The Film Project!" is more or less a derivative of the Will Smith–Chris Rock slapping incident at the 2022 Oscars, with Cody even copying Smith's F-bombs almost word-by-word.
  • Robo Cam: In "Robot Jeffy," at one point in the video, Mario tries to get Jeffo to eat green beans. Jeffo's point of view is shown, as he gets mail telling him not to eat the green beans. Jeffo's point of view is shown again when "Kill Mode" is activated.
  • Rotating Protagonist: A lead protagonist is never truly set in stone. The series often trades spotlights between characters. The series can switich between focusing on the Butt-Monkey Mario, the Insufferable Imbecile Jeffy, the Spoiled Brat Bowser Junior, or any other character.
  • Rotten Robotic Replacement: In "Robot Jeffy", Jackie Chu gives Jeffy detention when he takes a dirty dump in his diaper (or Triple-D'd, as Jeffy calls it) and tosses his diaper at Jackie Chu's face. Because Jeffy doesn't want to go to detention, Cody gets his robot, Codo, to make a robot of Jeffy named Jeffo to take his place. When Bully Bill bullies Jeffo, Jeffo enters Kill Mode and goes on a rampage, leading Codo to destroy Jeffo, sacrificing himself in the process.
  • Running Gag: Want to know how much? Look here.
  • Sadist Show: This series thrives on its characters acting like jerks and idiots.
  • Sarcasm Mode: In "Bowser Junior's Homework":
    Chef Pee Pee: I know! Maybe you should get that little stupid cucumber to help you on your exam since he knows everything! Maybe he can help you cheat!
  • Scolding the Fourth-Wall Breaker: In the episode, "Bowser Junior's Clown Car", Junior enlists Joseph and Cody's help to get a box that has Bowser's Clown Car in it, since he's too short. Cody points out that he, Junior, and Joseph are controlled by hands, and can go as high as they need to, leading to this exchange:
    Junior: Stop breaking the fourth wall, Cody!
    Joseph: Yeah, Cody! Always ruining stuff!
    Cody: Sorry.
  • Screw This, I'm Outta Here:
    • Cody has done this multiple times so far, with examples being "Bowser Junior's Credit Card!" and "Evil Chef Pee Pee!".
    • Pretty much Joseph's defining character trait, who's prone to leaving the situation the moment anything happens. Constantly lampshaded as a result.
  • Self-Deprecation:
    • In part one of "Bowser Junior's Summer School", Logan is one of the students in summer school, and Jackie Chu gives him a book called "YouTube for Dummies" and calls him dumb.
    • In "Bowser Junior's 1st Grade! Part 4", a puppet version of Logan says that he wants to make YouTube videos when he grows up. Jackie Chu calls the idea dumb.
    • In "Bowser Junior's YouTube Channel!", after watching one of their fake pranks on YouTube, Junior and his friends notice a comment from SuperMarioLogan himself saying that it was "fake and gay", and Junior calls him "stupid".

    Bowser: Don't-don't scream, Chef Pee Pee. His ass's going to military school.
  • Shorter Means Smarter: Being a retarded handicapped child, Jeffy is bigger in size compared to Mario, who is relatively smart but fails to make people believe him, even when he's innocent.
  • Shout-Out:

  • Show-and-Tell Antics: In "Bowser Junior's Summer School, Part 3", Junior wants to bring a cool toy to show and tell to impress his classmates, but he doesn't think any of his toys are cool enough, so he asks Chef Pee Pee, Bowser's personal chef, to come with him. At Summer School, Cody shows off his numerous medications (which takes over thirty minutes), Cecelia shows off a taco she bought from Taco Bell, Junior shows off Chef Pee Pee, Black Yoshi shows off his copy of Call of Duty: Ghosts, Pixie Goblin shows off his sword (and Officer Goodman arrests him for bringing a weapon to school as a result), Chris the Cucumber shares a "fact" that isn't true (Hawaii is a planet), Joseph shows off his phone (which is cracked from all the times he dropped it), and Toad shows an "educational" music video, which depicts him twerking with a woman.

  • Show Within a Show:
    • Charleyyy and Friends and Doofy the Dragon.
    • There's also two Channels Within a Show: Manly TV and Lifetime.
  • Sluggish Sloths: In "Chicken!", Cody invents a ray gun that can turn anything into a random animal. When Bowser Junior zaps Chef Pee Pee with it, the ray turns him into a sloth, causing him to talk incredibly slow.
    Sloth Chef Pee Pee: Jun...ior! What... did... you... do... to... me?!
  • Small Role, Big Impact: Charleyyy and Doofy are responsible for inciting major plot elements in a few videos including "Bowser's House Fire!", "Pop Rocks and Coke!", "Bowser Junior's Big Mess!" and "Black Yoshi's Job".
  • Snap Back:
    • Many episodes end with one or more of the characters getting killed.
    • Usually subverted whenever a major event happens, such as the characters moving into a new house, or "Jeffy's Parents!".
  • Sneaking Out at Night: Bowser Junior Sneaks Out! has Bowser Junior sneak out at night, which causes him to get arrested.

    • Bowser also threatens it to Junior in "Bowser Junior Gets Rabies!" for going outside in the rain.
  • Social Services Does Not Exist: A major issue in "Joseph's House!". Ever since Joseph's mom died on October 31, 2015, he started to become more insane. He's had to live in the dark due to no one paying the bills, he has no running water, his pet fish and dog are dead, he has to steal money from his mom's purse to pay for food, he has to imagine what video game to play whenever he plays his Xbox One, his dad is a zombie (and becomes a ghost not long after), and Screwball the Clown is his only roommate and living companion, but doesn't do anything to pay the bills.
  • Something We Forgot: In "Jeffy and Junior's Big Heist!", Jeffy tosses his ravioli at Bowser's signed underwear from Charleyyy, and when Chef Pee Pee finds out, he threatens to tell Bowser on him and Junior. Junior ties Chef Pee Pee up and locks him in the trunk of Bowser's car, intending to let him out after they fix Bowser's underwear. At the end of the episode, Junior gets the feeling that he forgot something, and sure enough, Chef Pee Pee is still in the trunk of Bowser's car, yelling for Junior to get him out.
  • Spell My Name with an S:
    • Charleyyy's name is spelled with three "Y's". In "Jeffy and Junior's Big Heist!", Junior asks Charleyyy why his name is spelled like that, and Charleyyy tells him that he got each "Y" for each divorce he had, because he wonders why he even got married in the first place.
    • In "Black Yoshi's Girlfriend Problem!",, a dating website for Yoshis, is always referred to in-universe as " with two E's." At one point in the episode, Black Yoshi logs onto "", and is horrified by what he sees (which isn't shown to the viewers).
  • Spoiled Brat:
    • Junior demands everything, often the demands he makes are ridiculous, unusual, or inconvenient, and when he doesn't get his way, he screams at the top of his lungs and begs until he does. It may be that he doesn't let people play with certain toys, demands specific foods they don't have, or just generally torments Chef PeePee while seeing himself as doing nothing wrong despite being a horrible person. Although as the years progressed, his bratty behavior had started to diminish.
    Junior: I WANT A HAPPY MEAL!!!!!!!!
    • It probably doesn't help that his father is even worse, often demanding food and telling Chef PeePee that he has five minutes to do it or else he will kill him. Luckily, Bowser is really bad at keeping time.
    • Jeffy is the biggest one in the series. He swears and throws tantrums when he doesn't get his way and has even deliberately broken things out of spite. And on a few occasions, he has deliberately gotten Mario arrested all because Mario tried to discipline him.
  • Spoiler Cover: The thumbnail for "The Zombie Apocalypse!" shows Junior in his zombified form from the ending.
  • Spotlight-Stealing Squad: As of late, Mario, Jeffy, Bowser Junior, and Brooklyn Guy are likely to be the main focus of an episode. It has gotten to the point where videos without them are plain rare. In particular, Mario's friends are often dropped in favor of Jeffy while the dynamic of Junior, Joseph, and Cody getting into shenanigans had become a consistent formula in the series.
  • Stalker with a Crush: Mario's major flaw is that he is a creeper towards women, especially Peach.
  • Status Quo Is God:
    • In "Black Yoshi's In Trouble!", Mario helps Black Yoshi change his life around, but ends up failing after Black Yoshi quits his job at McDonald's and goes back to playing Call of Duty.
    • In "Bowser Junior's Punishment!", Bowser decides to give Junior a five-minutes-in-the-corner punishment after he breaks his favorite cup and draws on a wall. Junior suffers and breaks down into depression, but luckily, it only takes a beating from Bowser to eventually snap him out of it.
    • In "Shrek's Diet!", Mario gets Shrek to eat healthier and exercise at a gym after Shrek suffers from a heart attack, only for him to go back to his regular cheesecake habit in the end.
    • "Bowser Junior Goes To Military School!" has Junior go into a mentally broken state after getting traumatized from military school, but thanks to his friends, he eventually snaps out of it.
    • Despite "Jeffy's Parents!" ending with Jeffy promising to behave better, Jeffy still acts like he usually does in the following videos.
    • In "Jeffy's Kids!", Jeffy fathers three children after getting a Cheerio box pregnant, but his bad parenting ultimately results in Junior eating two of his kids and the other one getting flushed down the toilet.
  • Stealth Pun: When Junior is worried about getting more bad luck, he's warned about a black cat crossing his path.
    Junior: (passes through Logan's cat Precious) Oh no, a cat! (he notices it's a multi-colored tabby) Well, at least it's not a black cat.
    Precious: Wassup nigga?
    Junior: (screams) Oh no! (runs away)
  • Stock "Yuck!":
    • Four words: Jeffy hates green beans.
    • Junior hates broccoli, as revealed in "Bowser Junior's Broccoli Problem!". When he attempted to flush it down the toilet, it only just made things worse.
    • Bowser is also revealed to (reportedly) hate vegetable casserole and red apples, in "Bowser's Broken TV" and "Bowser Loses A Tooth!" respectively.
    • Jeffy is sometimes shown to not like peas, for example in "Jeffy Gets Potty Trained!", and he is also revealed to have a bratty side as he claims he wants marshmallows instead of peas.
  • Straight Man: Mario being the Only Sane Man in his household, alongside Chef Pee Pee and Junior's friend Cody.
  • Subverted Kids' Show: The thumbnails, video titles, and descriptions seem innocent at first glance, but the series blatantly contains swearing, sexual references, and so on. It only dwelled further into this territory once the Human Puppets entered the picture, leading to the series giving off impressions similar to other puppet shows like Sesame Street, a work actually targeted at children.
  • Suddenly Shouting: This exchange in "The Little Boy Who Cried Wolf!":
    Penelope: Without the sheep, the wolf wouldn't even come!
    Cody: Huh, I guess I never really thought about it like that before... I mean, I guess I've never noticed because I only have ONE GODDAMN LINE!!
  • Summer School Sucks:
    • In the Bowser Junior's Summer School series, Bowser Junior fails kindergarten and has to do summer school. He's not happy about this since he hates school and his summer school teacher Jackie Chu gives everyone difficult homework.
    • "Jeffy's Summer School" has Jeffy get all Fs and he has to do summer school, meaning he can't go on vacation with Mario and Rosalina. After Jackie Chu drops off the summer school materials at the house (because he's going on vacation), Jeffy has Drawing!Jeffy do his work with Mario while Junior and Cody sneak into the school and change Jeffy's grades so he doesn't have to do summer school anymore.
  • Surprisingly Realistic Outcome:
    • Invoked by NASA in "Bowser Junior Goes To The Sun!". Having enough of Junior saying that the Sun is a planet, they were willing to spend millions to prepare a space shuttle and invite him to travel there then "prove" the public wrong.
    • Jeffy was most likely dropped off at Mario's door because his parents were annoyed and offended by him and didn't want to deal with him anymore. It was eventually confirmed that his mother was the one who dropped him off.
    • "Black Yoshi's House Arrest!" is full of this.
      • When Brooklyn forgets to put on his uniform when he gets to the school, everyone mistakes him for a school shooter and beats the crap out of him. As the police chief tells him, he ran into a school carrying a gun, without his uniform, telling everyone to get on the ground.
      • While the police chief lampshades that he was being beaten by kids, Brooklyn incredulously says, "What did you want me to do? Shoot em?"
      • Lastly, while the tracker was on Jeffy, Black Yoshi still violated his house arrest as he left the house to get KFC.
    • After Black Yoshi uses a megaphone to ask Mario for the new Call of Duty game in "Black Yoshi's Call of Duty Modern Warfare!", Mario goes deaf and needs to get hearing aids.
    • In "Black Yoshi's SuperPowers", well, Black Yoshi gets superpowers. But much to Mario's dismay, he just uses them to steal things. When an incredibly selfish and greedy person gets superpowers, they will most definitely do incredibly selfish and greedy things.
  • Take That!:
    • From "Black Yoshi's Job'':
    Announcer: "Call of Duty fans, go pre-order the new Call of Duty: Advanced Warfare! There's absolutely nothing different compared to the last Call of Duty, but we're gonna make a ton of money!"
    • In "Evil Bowser", after suffering Villain Decay, Bowser decides to summon the Devil to help him get his evil back. He does so by singing the "Evil Devil Chant", which is actually the "I Love You" song.
    • In "Luigi's Mansion Part 5", there's even one to his haters. They're shown, along with George W. Bush and others, as some of the worst people on Earth.
    • "Chef Pee Pee Gets Sick!" and "Bowser Junior's Playtime 3" feature take thats to The Good Dinosaur for being short, its nonsensical plot, and not living up to the same standards as Pixar's previous film, Inside Out.
    • In "Cody's Revenge!", when Bowser threatens to send Junior to Military School, one of the punishments the Brooklyn Guy says he's going to give to Junior is to make him watch Big Hero 6. Junior says that Big Hero 6 is the worst animated feature since Cars 2. This gets Bowser to reconsider.
    • In "Jeffy's Favorite Song!", Mario gets Jeffy an iPhone 7 after breaking his old iPhone, and proclaims that Jeffy only agrees to use it if he uses headphones. He then finds out to his horror that it doesn't have a headphone jack, resulting in him being forced to listen to the Bunny Do song.
    • Since the 2017 YouTube Adpocalypse, there have been many jokes about how YouTube has been age-restricting and demonetizing Logan's videos, and how Logan can't even show simple things such as medicine anymore.
      • "Jeffy Plays Minecraft!" in particular has take thats both to the aforementioned YouTube Adpocalypse and to modern Moral Guardians who refuse to admit their failures at parenting and instead pin it on the creators for making the offending content in the first place just so they can keep their inflated egos intact.
      • "Jeffy's Bad Christmas!" has three take thats in a row. The first is when Mario mentions that Jeffy was a naughty kid for getting his videos age-restricted, and the second involves Black Yoshi giving Mario a present, which turns out to be a YouTube error photo with a message saying "This present has been age-restricted". The third occurs right at the ending, when Cody shows his present to Junior and ends up getting the video itself age-restricted.
      • "Jeffy's YouTube Channel!" is filled to the brim with these, not to mention several pokes toward Logan Paul.
    • In "Cody Plays Tennis!", Cody says that Spike is a really weird Mario character, and then says that Spike is "apparently a fan f***ing favorite". This is an obvious jab at SML's main "competitor"note  Supermarioglitchy4's Super Mario 64 Bloopers's Fishy Boopkins character.
    • "The School Dance!" debuts Roy Gethard who stole all the girls. He seem to share the same first name as Chilly's new boyfriend after her and Logan's breakup.
  • Take That, Critics!: As of 2017, a few videos contain gags at the expense of the series' detractors and critics, with the most notorious case being "Shrek's Coma".
  • Tantrum Throwing: Jeffy tends to throw things when he is angry, such as throwing the couch and the TV off the balcony because Mario wouldn't buy him a game, throwing the Christmas tree out of the house because he didn't get any toys for Christmas, and throwing his plate of green beans whenever Mario tries to make him eat them.
  • Tap on the Head:

    • In "Chef Pee Pee's Birthday", Chef Pee Pee gives this speech to Bowser and Junior after they throw him a crappy birthday party:
    Chef Pee Pee: Really, is this what my birthday consists of? Come on, Bowser, you can do better than this! Come on, really?
    Bowser: Stop being ungrateful, Chef Pee Pee! We all tried really hard, okay?
    Chef Pee Pee: Well, you didn't try hard enough! I swear, you guys suck! This is the worst birthday ever!
    Junior: Wait! Dad, he didn't like the gifts we gave him?
    Chef Pee Pee: No, I didn't like the gifts, they were horrible! [To Junior] You took yours back, [To Bowser] and you gave me a spatula! Oh, I wonder what you gave me a spatula for...
    Bowser: Obviously to cook, duh!
    Chef Pee Pee: Of course!
    Junior: What else would you do with a spatula, Chef Pee Pee? You cook with it!
    Chef Pee Pee: You guys are selfish! [To Bowser] You buy me something to help you, [To Junior] and you take yours back and you spend my birthday money on a video game!
    Junior: But the video game's fun!
    Chef Pee Pee: You know what? F*BLEEP* you guys! Don't talk to me for the rest of the day, okay? Know what? The rest of the month! Even better, the rest of the year! I'm so sick of you guys! You guys think of yourself and only you!
    Chef Pee Pee: I hate you, I hate you because you're an annoying little brat! All you do is come in the kitchen, bother me, while I'm cooking, and then you bring the toys in there like I wanna play with you, but I'm not a child! I don't have time for that! I have to wash dishes! And all you do is make messes in the kitchen! [6 hours later] And the reason I hate you the most Junior? Is because you exist! Would not—why would God even create a little bastard like you?! Please tell me—in this beautiful universe He could create anything else! But it's OK, I'mma take you out of this universe. Any last words Junior?
  • Theme Naming: Rosalinas' exes all have the letter D in their names somewhere, like Dak, Brad, Super D, D Money, etc. A more humorous one is the implication she also nicknames them by their penis sizes as shown with Super D's full monikernote , Super Big D, and her almost calling Mario Average D.
  • They Killed Kenny Again: The SML characters die on a semi-regular basis.
  • Throw the Dog a Bone:

    • In "Jeffy Gets Potty Trained!", Mario is tired of changing Jeffy's diapers (especially since he's way past the normal potty-training age) and so he and Rosalina try unsuccessfully to potty-train him. Jeffy doesn't poop in the toilet, but does poop in the sink and the bathtub. Eventually, Mario and Rosalina train Jeffy to use the litter box.
  • Too Dumb to Live: Most characters qualify, but Junior is probably the best example as he once put his tongue on Cody's drone, resulting in Bloody Hilarious Tongue Trauma. He also saw Doofy the Dragon light himself on fire and thought it would be cool to start a fire.
    • Toad might be an even better contender. He eats Shrek's cheesecake and hides in a blender to avoid Shrek, completely forgetting the blender is see-through glass, so Shrek spots him easily and then grinds him up into a gory, disgusting blob with the blender.
      • Toad also tried to help Luigi catch souls, and managed to suck up his own soul three times.
    • As if these two weren't enough, Jeffy somehow manages to outdo them both; he even willingly played Russian Roulette once.

    • Bowser Junior loves Happy Meals, to the point where two episodes focused on him demanding Chef Pee Pee to buy them for him. He also likes Chips Ahoy cookies, as in "Bowser Junior's All-Nighter!", he competed against Joseph and Cody to see who could stay up the longest to eat the last one. He also wanted Chef Pee Pee to buy them for him in "Bowser Junior's Cookies!", to the point of posting sticky notes with "COOKIES" written on them all over his apartment. Junior also loves macaroni and cheese, as alluded to in several videos, including "Bowser Junior Gets Jinxed!" and "Jeffy's Birthday!". Also, in "Evil Chef Pee Pee!", he told Chef Pee Pee to get just it for him when Chef Pee Pee asked him what he wanted from the grocery store.

Later at the end of the video, Mario tries kissing Rosalina again, only to spray her with his new FLUDD.
  • Unfortunate Names: Chef Pee Pee has dressed up as a woman twice at the request of Bowser. His first time was when he was faking being Junior's new mom so Bowser could get a Charleyyy and Friends DVD box set, and the other was for Mario's date to keep Mario from committing suicide. Both times Bowser decided to name him based on stuff in the environment. The first name? Peppers Refrigerator. The second name? Lamp Doorknob.
  • Universal Remote Control: In "The Remote!", Junior gets a remote control in his Happy Meal. This remote has the ability to pause time, change people's language from English to Spanish, fast-forward time, mute people, rewind time, and even age-restrict the episode.
  • The Unreveal: At the end of "Jeffy's Sister!", Jeffy is about to reveal who his real mother is, when the video suddenly cuts to the SML Question.
  • Unsettling Gender-Reveal: In "Mario's Date!", Mario goes on a blind date with Kirby, whom he thinks is a female. But in the end, Kirby reveals that he is a homosexual male, much to Mario's anger and frustration.

  • Verbal Tic: Officer Goodman's "m-kay".

    • Shrek calls his friends "Donkey", and his enemies "Lord Farquaad".
    • Joseph loves saying "dude", just as much as Tanner from Bowser Junior's Summer School does.

  • Vocal Dissonance: Compared to their canon selves:
    • Mario doesn't sound anything like he does in the games; not only is his voice more high-pitched, but he also lost his trademark Italian accent.'
    • Bowser Jr has a very different voice. Despite clearly being a kid, he has an adult-sounding voice, since Logan plays him.
    • Yoshis normally have cute, high-pitched sounding voices, but Black Yoshi has a very deep, Gangster sounding voice.
    • Woody has a much deeper voice compared to the higher pitched voice from the Toy Story films.
  • Vocal Evolution:
    • Junior's voice has matured over time, originally sounding much more baby-ish and with a slight Elmer Fudd thing going.
    • Chef Pee Pee had a thicker accent early on.
    • Brooklyn Guy actually had a thicker Brooklyn accent back then.
    • Cody originally sounded more like Mr. Crocker.
    • Jeffy's voice has also matured over time, losing the slight Elmer Fudd thing and sounding less dopey overall.

    • "Joseph's Mom!". Joseph finally reveals to Junior and Cody that he killed his mom on October 31, 2015...except that he didn't. It turns out that Joseph's mom won the lottery, renounced her parenting for him and used a plastic skeleton and a wig to trick Joseph into thinking that he killed her. Since then, she's been living a new life with a new husband.
    • "The Human Potion!". Jackie Chu finally gets glasses so he can see properly, and finds out that Junior, Joseph, and Cody are turtles. This causes a sudden uptick in Fantastic Racism, as the trio are expelled for not being human (Jeffy also tries to get expelled by saying he identifies as a turtle, also pointing out that it's 2019, but this is just a throwaway gag pandering to Jeffy fans). Then, Goodman evicts Bowser from the house due to being a turtle and thus not having a Social Security number, even threatening to call animal control (surprisingly, he does it in a very calm manner rather than flipping out like he would with Mario). After Tyrone and Judy have a parent-teacher conference with Jackie Chu that goes nowhere because they're idiots, Cody comes up with a potion that will turn them into humans. And lo and behold, it works: Junior still has his horns, Joseph is black, and Cody is an utter nerd with hair he can style into bangs if he so chooses. Junior then gives Bowser the potion, turning him into a Fat Slob with pink bunny slippers and crazy eyes. So, the kids get back into school, and Bowser gets to stay. And according to Word of God, this is a permanent change so they can start swearing again.note

    • In "Cody's Revenge!", Junior knocking over the jar of their dead cat, Mittens, and her ashes, breaking the jar and spilling the ashes.
    • In "Bowser Junior Gets Rabies!", Junior turning from a hallucinating Non Sequitur into a rabid wild biter.
    • Two in "Bowser Junior's Painting!"; the first being Junior dropping his canvas onto his color plate by accident, and the second being Jacques Pierre François cutting his ear and putting it on his black canvas during an art duel with Junior.
    • In "Jeffy's Bad Word!", Mario spanking Jeffy as punishment for the latter saying the F-word (no, not that F-word).

    • In "Career Day!", Brooklyn Guy coming in the classroom when Penelope tells her father to come in, revealing that he's Penelope's father.
  • What Do You Mean, It's for Kids?: In-Universe example: Doofy the Dragon. The show is about violence and drugs and Doofy commits suicide in almost every episode.
  • What Happened to the Mouse?: Happens constantly and without fail throughout the series. Plot points or characters are either forgotten about for long periods of time or dropped entirely. This isn't helped by the fact that many of the episodes simply stop before said plot threads are even solved. Status Quo Is God also ends up playing a huge factor in many of these instances.
    • A more recent specific example can be seen in "The Baseball Game" Where Shrek just up and disappears during the second half of the short for reasons never explained.
  • White Dude, Black Dude: A part of the humor between Mario and Black Yoshi is that Mario is never certain what to do while Black Yoshi often has a bad or destructive idea that may or may not work in the end. Furthermore, as much as Mario gets annoyed with Black Yoshi, Black Yoshi often is treated as the more outgoing and powerful of the duo, where Mario is (prior to Rosalina's appearances) more of a coward who cries.
  • Whole-Plot Reference:
    • Who thought "The Purge!" wasn't the same as the movie?
    • "Home Alone", "Home Alone 2" and "Jeffy's Home Alone!" has Junior (Jeffy in the latter) as the role of the main character, and the burglar duo (Terrible Trio in the first video) as the roles of the burglars robbing his house.
    • "Taken" has Cody as role of the main character, and Ken as the role of the daughter who gets kidnapped.
    • Both "Jeffy's Fairy Godparents!" and "The PowerPuff Jeffy's!" are based on the Fairly OddParents pilot and The Powerpuff Girls respectively, with Jeffy playing the role of the main character(s).
  • Why Did It Have to Be Snakes?:
    • During the Bowser's Biggest Fear trilogy, Bowser develops a fear of bananas, and later milk. The former is later referenced in Mario and Bowser's Stupid and Crazy Adventures.
    • In "Bowser Junior's Biggest Fear!", Junior is revealed to be afraid of cotton balls.
  • With Friends Like These...: Junior and Cody are considered to be friends, yet they do not really get along with each other. For example, Junior tricks Cody into playing "catch the hammer with your mouth" in "Bowser Loses A Tooth!", so Junior can take Cody's teeth and get money.
  • World of Jerkass: And How! (Although Woody is a exception)
  • Worth It: Brooklyn T. Guy's opinion on the price of sending Junior all the way to the Sun in "Bowser Junior Goes To The Sun!" just so they wouldn't hear him saying that the Sun is a planet. Needless to say, it didn't help that it got Junior killed in the process.
  • Would Hurt a Child:
    • Bowser usually beats up Junior (specifically with a belt) when the latter screws up.
    • Principal Steinbeck's beatdown on Toad in Bowser Junior's Summer School.
    • Charleyyy throwing his baby daughter down a staircase can also count.
    • Brooklyn T. Guy doesn't do well with kids, especially Junior. He tortured him in Bowser Junior Goes To Military School!, tried to kill him in "The Purge!", and sent Junior to the Sun to get him killed in "Bowser Junior Goes To The Sun!".
  • Wrong Restaurant: In "Bowser Junior's Breakfast", when Chef Pee Pee takes Junior to Waffle House, Junior tries to order pancakes, despite Chef Pee Pee telling him that Waffle House doesn't sell pancakes. Chef Pee Pee then convinces the manager to smash up a waffle and pass it off as a pancake. Junior also tries to order a Pepsi, as well as a pizza, despite the fact that Waffle House sells Coke and the fact that it does not sell pizza.
  • Yank the Dog's Chain:
    • Mario getting Jeffy, putting an end to a three-month period of hanging out with Rosalina.
    • Freddy Fazbear's Pizza burning down can also count for Chef Pee Pee, in the Chef Pee Pee Quits! series. Although the location returns in "Bowser Junior's 8th Birthday!".
  • Your Head Asplode:
  • You Wanna Get Sued?: In "Jeffy's Adult Happy Meal!", when Jeffy brings Banjo and Kazooie to Junior's house, Junior tells Jeffy to get them out of there, as they're part of "The bad company that tried to sue us!", only for Brooklyn T. Guy to point out that Banjo and Kazooie are actually owned by Rare, a subsidiary of Microsoft. When Junior argues that Banjo's first game was on the 64 console, Brooklyn tells them that Microsoft bought the rights to him after that console's lifespan ended, which was why his third game on the Xbox 360 was of considerably inferior quality. Junior then retaliates by saying that Banjo was in the new Smash fighting game, but Brooklyn assures Junior that they're still in the clear. Not wanting to take any chances, Junior tells Banjo and Kazooie to leave.
  • You Are Who You Eat: Cody's Curse revolves around this, where Cody curses everyone into what kind of animal they eat, they turn into that animal.

SML Question: How has TV Tropes ruined your life?


Cody makes fun of Junior's mom

Cody finally makes a mom joke back at Junior but because Junior doesn't have a mom it's a lot sadder than he expected.

How well does it match the trope?
