    Tropes N-O 
  • Nailed to the Wagon: In the episode "Let's Play Trap-Trap", Kaeloo hides all of Quack Quack's yogurt so he can't eat it for one hour. Unfortunately, he undergoes "yogurt withdrawal", and then he hallucinates his friends as giant yogurts and tries to cannibalize them.
  • Nap-Inducing Speak: A Running Gag on the show is for someone to give a really long speech or lecture, and for one or more of the audience members to fall asleep.
  • Narrator: Episode 139 featured a narrator, who the cast found so annoying that Stumpy got Mr. Cat to shoot him with a bazooka at the end of the episode.
  • Natural Spotlight: A Running Gag in "Let's Play the Quest for the Wholly Gruel" is that a person, or the Gruel itself, gets illuminated by light from the sky whenever someone says "Wholly Gruel".
  • Nature Tinkling:
    • In Episode 125, Kaeloo has a Potty Emergency and after the toilet is accidentally destroyed, she's forced to go under a tree instead.
    • Episode 135 has Stumpy peeing outdoors while misquoting C'est La Faute À Voltaire from Les Misérables with the lyrics changed to talk about peeing.
  • Neck Lift: Bad Kaeloo does this to Mr. Cat Once an Episode.
  • The Needless: One episode has the characters visit an alternate universe where the world is perfect in every way, and the inhabitants of said world are so perfect that they don't need to eat, drink, or even breathe to live.
  • Negated Moment of Awesome: In one episode, Mr. Cat and Stumpy are playing soccer and will win the game if they can just score one goal. They put all their strength into one kick and kick the ball at the same time. The ball goes so fast it catches fire... and goes just to the side of the goalpost.
  • Negate Your Own Sacrifice: The indestructible Quack Quack has "sacrificed" himself several times for his friends' safety.
  • Negative Continuity: Several characters have been decapitated, blown up, launched into orbit, driven to madness, turned into zombies, trapped in alternate dimensions or different time periods... Heck, the world even blew up once! Yet everything is always back to normal in the next episode.
  • Never My Fault:
    • In the episode "Let's Play Golf", Stumpy says something to Kaeloo shortly before she hits a golf ball. When Kaeloo fails to hit the ball, rather than admit her bad golf skills, she accuses Stumpy of making her lose her concentration by talking. Stumpy even lampshades this by saying that she's just blaming him for her own mistakes.
    • In Episode 131, Mr. Cat's bullying of Quack Quack leads to Kaeloo hitting him, which was quite justified. Instead of accepting that it was his fault for instigating the fight, Mr. Cat spends the rest of the episode refusing to talk to Kaeloo or make eye contact with her, because he thinks it was her fault.
  • Newhart Phone Call:
    • Whenever Ursula is talking on the phone with Stumpy, this happens so that the audience doesn't see her.
    • In "Let's Play Time Travel", when Mr. Cat calls the time machine company so that he can order a time machine, only he can be heard speaking coherently while the person on the other end of the line can only be heard as sped-up gibberish.
  • New Job as the Plot Demands: Depending on the episode, the characters, especially Kaeloo and Mr. Cat, tend to have new jobs if the plot requires them to. One episode even lampshades this; after holding several different jobs through the episode, Kaeloo, as a police officer, arrests Stumpy and Quack Quack for robbing a bank, and then tells them that if they need an attorney for their court hearing, she'll be there to do that for them too.
  • New Job Episode: Episode 93 has Stumpy and Quack Quack learning how to be firefighters. They are so incompetent that they fail to learn anything properly and the job only lasts for one episode.
  • New Media Are Evil: Episode 146 was about Kaeloo learning about smartphones from Stumpy. While she does learn that they have some benefits, like being able to watch movies, listen to music, and read the news, she primarily encounters problems such as violent mobile games, scammers, and the fact that being on the phone is a waste of time.
  • New Neighbours as the Plot Demands: How Pretty and Eugly were introduced. Stumpy asks who they are, and Kaeloo is surprised that he doesn't know that they're their neighbors.
  • New Powers as the Plot Demands: The narrative says that Quack-Quack has superpowers, but never specifies what exact powers he has, which means that an episode can introduce Quack-Quack having a superpower the audience has never seen before and nobody bats an eye, with Quack-Quack retaining these powers in future episodes.
  • Nice Job Breaking It, Rivals!: In Episode 2, Kaeloo and Mr. Cat are playing doctor and they both want Quack-Quack to be their patient. During their fight over him, they start playing tug-of-war with his body and end up pulling too hard, causing Quack-Quack to get ripped in half. Quack-Quack being unkillable, this doesn't do any permanent damage, but he decides to quit the game.
  • Ninja Pirate Zombie Robot:
    • In "Figurines", Stumpy tries to play a game with a bunch of figurines called "ninja terrorists".
    • In Episode 219, Kaeloo, Stumpy, Quack-Quack, Mr. Cat, and Cramoisie play a game called "zompires" (a mix of zombies and vampires) that was invented by Stumpy. The zompires have slow bumbling movements like zombies, and like vampires, they levitate and burn in the sun.
  • Nobody's That Dumb: In "Trap-Trap", Quack-Quack undergoes withdrawal symptoms after his yogurt is taken away from him by Kaeloo, which makes him lose his mind and attempt to cannibalize the others. Mr. Cat tells Stumpy that the problem will be solved if they give him some yogurt, and Stumpy gets Quack-Quack's yogurt from the place Kaeloo hid it. Due to Quack-Quack now being an insane cannibal, Mr. Cat says Stumpy should be the one to give it to him, but Stumpy refuses because "I may be nuts, but I'm not crazy!"
  • No Fourth Wall: The characters speak directly to the audience and are fully aware of the fact that they're in a cartoon.
  • No-Holds-Barred Beatdown: Once an Episode, Bad Kaeloo does this to Mr. Cat as punishment for whatever evil things he did through the episode.
  • Noir Episode: "Let's Play Detectives".
  • Non-Fatal Explosions: Stuff blows up in every episode, yet nobody dies (usually).
  • Non-Mammal Mammaries: One episode had Mr. Cat and Quack-Quack fighting over a book with pictures of skimpily dressed women in it. Since they live in a World of Funny Animals, all the women in the book are anthropomorphic animals, and one of them is a large-breasted ostrich.
  • Non Sequitur: In one episode, Stumpy develops an obsession with vampires, and Kaeloo decides to give him psychotherapy to deal with it. Lying on the Freudian Couch, Stumpy explains how he's been having recurring nightmares about... being eaten by a "were-dumpster". Kaeloo even lampshades how that has nothing to do with vampires.
  • Nonverbal Miscommunication: Sometimes happens with Quack Quack.
  • Noodle Incident:
    • In the Season 1 finale, Stumpy remarks that Mr. Cat seems to know a lot about funerals. Mr. Cat replies, in a sad tone of voice, that he knows "a little too much" about them.
    • In one episode, Pretty mentions that some girl dared to disagree with her about something. Rather than say exactly what she did to the girl, she simply ends the story by saying "That poor girl..."
    • In Episode 94, Kaeloo mentions something about Stumpy being kicked out of art class at school. She doesn't say why, and the incident is never brought up again.
    • Episode 139 follows the adventures of Ratman, "the world's worst superhero". At the beginning of the episode, we find out that he somehow set the city's ice rink on fire. The only detail we get about the fire is that "he didn't do it on purpose".
  • No Party Like a Donner Party:
    • Quack Quack tries to cannibalize Kaeloo and Stumpy in "Let's Play Trap-Trap" after undergoing "yogurt withdrawal" and hallucinating them as giant yogurts. Mr. Cat manages to rescue them, but not before Quack Quack eats half of Kaeloo's brain.
    • In Episode 61, Stumpy tries to eat Kaeloo after being stranded on an island. He can later be seen gnawing on Eugly's ear.
  • Not a Game: Practically everything that happens on the show is treated as a game by everyone except Olaf, who winds up using this line very often.
  • Not a Mask:
    • In Episode 65, Mr. Cat wears a disguise as Pretty. Kaeloo thinks that the real Pretty is Mr. Cat disguised as Pretty and tries to pull her face off until she sees the real Mr. Cat somewhere else.
    • Happens to Pretty again in Episode 83, this time with Stumpy thinking she's Ursula in disguise.
  • Not Hyperbole: In one episode, Mr. Cat threatened to kill Kaeloo and Stumpy if they touched him... while holding a knife to Kaeloo's throat and a bazooka to Stumpy's head.
  • Not Me This Time: Some episodes have people accuse Mr. Cat of being the villain when in reality he has nothing to do with whatever happened.
  • Not So Above It All:
    • Mr. Cat always pretends he can't be bothered to play games with the others, but when they don't invite him to join them, he gets really, really mad.
    • In one episode, Mr. Cat opens a restaurant that is clearly designed to be a Take That! at McDonald's. When the food gives Pretty multiple organ failure, everybody starts protesting the restaurant, so he offers them free toys with their food. Everybody except Kaeloo rushes off to get toys while she looks on in disapproval, but when a toy lands near her feet she plays with it after making sure nobody is looking.
  • Not-So-Imaginary Friend: In Episode 157, Stumpy reveals that he has imaginary friends and Kaeloo, Mr. Cat, and Pretty mock him for it. At the end of the episode we find out that one of them, Baron Banana the Cyborg T-Rex, is in fact real but simply invisible, and the episode ends as he prepares to attack Kaeloo, Mr. Cat, and Pretty for the way they treated Stumpy.
  • Not-So-Innocent Whistle: Stumpy does this whenever he's done something stupid or screwed something up and someone demands to know who did it.
  • Not What It Looks Like:
    • In Episode 192, Kaeloo tries to show Stumpy how the Earth moves around the Sun by spinning around while simultaneously moving around Mr. Cat, who is asleep on a lawn chair. The constant spinning makes her dizzy and she lands on top of Mr. Cat, who wakes up to find Kaeloo lying on top of his body. Kaeloo desperately tries to clarify the misunderstanding.
    • While Kaeloo is on the phone with Pretty, Mr. Cat, who is in the same room as Kaeloo, keeps annoying her until she snaps and starts to beat him up; Pretty, who doesn't know what's going on, is implied to have assumed that Kaeloo and Mr. Cat are doing the horizontal mambo.
  • Number Two for Brains: This trope comes into play whenever Stumpy is working under Mr. Cat.
  • Oblivious to Love: Kaeloo and Mr. Cat are both unaware of the fact that the other is attracted to them. However, as the series progresses, they start to slowly become more aware of each other's feelings.
  • Obfuscating Disability:
    • In Episode 128, while trying various methods to trick people into giving him money, Stumpy tries faking being crippled. Since the show has a Minimalist Cast, everyone already knows each other, and Kaeloo tells right away that he's faking. She pays him anyway because it was such a good act it would have seemed believable to anyone else.
    • In Episode 138, Mr. Cat wonders if Stumpy might have dyspraxia, and notes that that might explain his inability to do chores. In reality Stumpy is just lazy, but he sees this as an opportunity to get out of doing chores forever, so he deliberately fails all the tests Mr. Cat performs on him to check for the disorder. Kaeloo knows that Stumpy is faking, so after Stumpy is diagnosed with dyspraxia by Mr. Cat, Kaeloo decides to give Stumpy medication to treat his symptoms in the form of injections. Stumpy is Afraid of Needles and immediately cleans up his room to prove that he's been "cured" to avoid taking the medicine.
  • Ocular Gushers: Everyone cries this way, most of the time.
  • Odd Friendship:
    • Kaeloo and Mr. Cat. One is kind, friendly, cheerful and idealistic, and the other is grouchy, rude, lazy and sarcastic, yet they're still very close friends.
    • Stumpy and Quack Quack are best friends. Stumpy sucks at everything, is a complete idiot and is usually a jerkass to his friends because of the way they treat him. Quack Quack, on the other hand, is a Nice Guy despite the bad treatment he receives, he is extremely talented at everything and is a "genius".
    • The Rules is a personification of the concept of rules and takes games very seriously as a result. Despite this, out of all the characters, she ends up becoming closest to Mr. Cat, who is lazy, laidback, and rebellious.
  • Offhand Backhand: Quack Quack does this to Mr. Cat in "Let's Play Prince Charming" after the latter pushes his Berserk Button.
  • Official Couple:
    • Quack Quack and Eugly.
    • Stumpy and Ursula.
  • Offscreen Teleportation: Mr. Cat is insanely capable of doing this, even without one of his cat flaps. In one episode, Mr. Cat and Stumpy are inside a closed room (and Mr. Cat is tied to a chair). Stumpy exits the room and closes the door to find Kaeloo and Quack Quack outside. By the time Stumpy and Kaeloo have spoken one or two lines, Mr. Cat has not only untied himself, but somehow gotten out of the room and stolen the car.
    • In another episode, Kaeloo is teaching Stumpy how to use a fireman's pole. She puts the pole just next to a cliff, jumps off the cliff and uses the pole to slide down while Stumpy watches from the cliff. Suddenly, Kaeloo appears behind him and pushes him off.
  • "Oh, Crap!" Smile: Mr. Cat usually does this when Bad Kaeloo is about to beat him up, or even when Kaeloo gets mad without transforming.
  • Oh, No... Not Again!:
    • In the Halloween Episode, this is everyone's reaction to Stumpy's stupid zombie impression (which involves dancing like in Thriller).
    • In one of the earlier episodes, Mr. Cat invents a machine which hurts Quack Quack, prompting Kaeloo to say:
    Kaeloo: Mr. Cat, if this is another one of your mean-spirited, two-bit inventionsnote ...
    • In Episode 110, Kaeloo and Quack Quack drag Stumpy to a psychotherapist, and he starts screaming that he doesn't want to go the the psychotherapist's office "again".
  • Once an Episode:
    • Kaeloo Hulking Out.
    • Mr. Cat torturing Quack Quack with some weapon.
    • Kaeloo yelling "MISTER CAAAAAAAT!" (or "STUMPYYYYYYY!" or "PRETTYYYY!").
  • One-Hit Wonder: In one episode from Season 2, Kaeloo, Quack Quack, Mr. Cat, Eugly and Pretty form their own rock band and make up a song that becomes very popular. The group winds up quitting the music business because at their second concert, which was also going to play the same song, the fans cheer so loudly that they (and Stumpy, who was backstage) all go deaf.
  • Only in It for the Money: In "Let's Play Spies", Mr. Cat assures Kaeloo that he wouldn't have betrayed her if not for the fact that he badly needed the money.
  • Only One Name: Everyone except Mr. Cat. Even in his case, his first name is not revealed.
  • Only Sane Woman: Eugly fills in this role. Kaeloo is a Cloud Cuckoolander who has no idea what's going on around her, Quack Quack is addicted to yogurt, Mr. Cat is Ax-Crazy, Pretty is a Stalker with a Crush who's also obsessed with beauty, Olaf wants to Take Over the World, and Stumpy is... Well, Stumpy. When Eugly is absent from an episode, the role is usually shifted to Kaeloo or Mr. Cat.
  • Only the Pure of Heart:
    • In "Let's Play the Quest for the Wholly Gruel", Kaeloo says that only the pure of heart can get the Gruel.
    • In Episode 105, it's stated that only people with pure hearts should activate the switch. The person who does wind up activating it is anything but pure of heart - it's an angry Stumpy, out to get revenge on his friends.
  • Ooh, Me Accent's Slipping: Mr. Cat's voice actor sometimes slips back into his Australian accent, which results in Mr. Cat having a weird accent that sounds like a mix between American and Australian at times.
  • "Open!" Says Me: Mr. Cat shoots the door to Olaf's lair open in Episode 104.
  • Open the Door and See All the People: Parodied in one episode where Stumpy opens the door and a crowd of random people start throwing things at him for no reason at all. He then asks why they are there.
  • Opposites Attract: Kind, friendly, cheerful Kaeloo and sarcastic, grouchy, rude Mr. Cat have crushes on each other, but they aren't aware that the feeling is mutual.
  • Orphaned Etymology: The cast mention people like Britney Spears, shows like House and places like Hawaii... all while living on Planet Smileyland, not Earth.
    • In one episode, Stumpy actually says that the cast went on vacation to Australia!
  • Ostrich Head Hiding: Quack Quack does this when playing hide and seek in Episode 70. Despite being a duck and not an ostrich. It works on Kaeloo, Interdimensional Stumpy and Interdimensional Quack Quack.
  • Other Me Annoys Me:
    • In the episode "Let's Play Astronauts", the main four go to an Alternate Universe where Kaeloo's transformation happens in reverse, Mr. Cat and Quack Quack have each other's personalities and Stumpy is a genius. While Kaeloo, Quack Quack and Mr. Cat hit it off with the other counterparts, Stumpy's math-loving, comic-book hating Insufferable Genius counterpart annoys him to no end. It's all in one of Stumpy's dreams.
    • In Episode 70, the main four meet their "interdimensional" counterparts, including a version of Kaeloo who is a strict teacher, an Insufferable Genius Stumpy, and a stupid Mr. Cat, who quickly make enemies out of the main four.
  • Out-of-Character Moment:
    • For whatever reason, Pretty is nice to the others in Episode 57, where she treats Kaeloo like her best friend and treats Stumpy like an actual person.
    • Kaeloo cheats at golf in "Let's Play Golf", manipulates Mr. Cat's emotions and shows no remorse for it in "Let's Play Courtroom Drama", and sets up a rigged game show for Mr. Cat to participate in where he would suffer even if he won in Episode 58.
    • The normally intelligent Mr. Cat does unbelievably stupid things in episodes like "Let's Play Circuses" and Episode 106.
    • In "Let's Play Golf", Kaeloo cheats, Quack Quack gets mad at Mr. Cat instead of forgiving him, the normally intelligent Mr. Cat thinks that the planet isn't round, and the idiot Stumpy is the only one who doesn't fall for Kaeloo's trick.
    • Episode 133 has Stumpy and Quack Quack act like elitist snobs, Pretty show remorse for being mean to Kaeloo and Mr. Cat being very, very nice to Kaeloo.
    • Kaeloo normally tries to portray herself as pure and innocent, but in Episode 141, while on a parody of The Voice, she ends up wearing a revealing outfit and performing a sexually suggestive dance because she thinks it'll help her win.
    • In Episode 105, Eugly, who is normally one of the nicest characters in the show, is seen laughing at Kaeloo when she gets insulted by Olaf.
    • In Episode 144, both Kaeloo and Mr. Cat are out of character. Quack Quack gets possessed by a demon, with visible effects; he now has horns, demon wings and tattoos. Mr. Cat is completely oblivious to the fact that something is wrong, and Kaeloo starts to realize that something is different, when normally it would be the other way around. Other strange things include Kaeloo yelling "YOU LOST!" at Stumpy and laughing when she beats him, while normally she would console him about it, and Mr. Cat is nice to everyone and keeps yelling about how delicious sausages are.
    • In Episode 147, Kaeloo and Mr. Cat are nice to each other and to Stumpy, when usually they would spend the episode fighting each other and bullying Stumpy.
  • Overly Narrow Superlative: Pretty says that Eugly is her favorite sister, but acknowledges that Eugly is also her only sister and therefore her favorite by default.

    Tropes P 
  • Pain-Powered Leap:
    • Mr. Cat does this in "Let's Play Figurines" when Stumpy pokes a voodoo doll of him with a sharp object.

  • Parental Bonus:
    • In the episode "Let's Play House", the characters play a game of "house" with Kaeloo as their mother and Mr. Cat as their father. When the kids leave the house, Mr. Cat turns out the lights, lies on top of Kaeloo, and asks her if they can perform their "conjugal duties" together. Not too many children would be familiar with what a "conjugal duty" is.
    • In one episode, Kaeloo lists off all the flaws she can think of that Mr. Cat has: he's "dishonest, hypocritical, egoistic, greedy, lazy, sly, and libidinous". That last word would fly over many kids' heads, but the parents would likely notice that Kaeloo is essentially complaining that Mr. Cat is too horny.
  • Parental Favoritism: Mr. Cat was apparently his mother's favorite child, to the chagrin of his two older brothers.
  • Parental Incest: Mr. Cat mentions having developed an oedipus complex at some point in his life and having fallen in love with his mother.

  • Parody Episode: Episode 69 is a parody of Dora the Explorer.
  • Parody Magic Spell: Subverted in "Let's Play Happy Rotter", an episode parodying Harry Potter. Kaeloo says that there are lots of spells ending in "us" and "or", but they turn out to be legitimate-sounding magic spells instead of English words with suffixes.
  • Parody Names: One of Kaeloo's favorite book series is "Happy Rotter", a story in which a young wizard named Happy Rotter (Harry Potter) and his friends "Red" (Ron) and "Morpione"note  (Hermione) who go to a wizard school and face off against the evil dark wizard "Voldemob" (Voldemort), who murdered Happy's parents when he was a baby.
  • Patchwork Kids: Quack Quack's Imagine Spot of Kaeloo and Mr. Cat's children in "Let's Play Babysitting" depicts orange, whiskered tadpoles.
    • Discussed in Episode 148. Stumpy and Mr. Cat wonder what kind of babies Quack Quack (a duck) and Eugly (a rabbit) would have if they got married. They then imagine the results to be freaky hybrids with duck bills and rabbit teeth.

    • In Episode 105, when Mr. Cat gets angry at Kaeloo, Stumpy and Quack Quack, he goes around kicking sheep and smashing trees with golf clubs in order to calm himself down.
    • When Stumpy suffers a misfortune due to a certain object, like losing a video game or his laptop not picking up the Wifi signal, his reaction is to smash the video game console or laptop into pieces in anger.
  • Perfectly Cromulent Word: Stumpy frequently invents his own words, like "tentacools", and insists that they are real words.
    Kaeloo: Don't you mean "tentacles"?

  • Perpetual Poverty: The main four. Lampshaded by Mr. Cat when he finds out that Quack Quack has no money and asks how the heck he pays for all the yogurt he eats.
  • Perp Sweating: Mr. Cat does this to Quack Quack the duck while trying to get him to confess to a crime he obviously didn't commit. In order to be more cruel, he turns up the lights so much that they actually burn Quack Quack, and then he decides to slam him on the head with a book each time he claims to not be guilty.
  • Personality Swap: In one episode, Stumpy and Quack Quack get their hands on some animation software and decide to take over the episode. The first thing they do is swap Kaeloo and Mr. Cat's personalities, making Mr. Cat kind, cheerful and friendly, and Kaeloo rude, grouchy, sarcastic and lazy.
  • Perverted Drooling: Mr. Cat does this when having a daydream where he is being massaged by numerous clones of Kaeloo.

    Stumpy: I love you a lot, guys... you know that, right?
  • Played for Drama: In Episode 58, Mr. Cat goes on a rigged game show which tortures it contestants physically and psychologically; instead of brushing it off like a regular cartoon character would, he's legitimately terrified and almost traumatized.
  • Playing House: In the episode "Let's Play House".
  • Playing Sick: Stumpy does this in Episode 138 in order to avoid cleaning his incredibly messy room. Kaeloo immediately sees through the ruse, but Stumpy refuses to admit he's faking. Kaeloo ends up using the fact that Stumpy is Afraid of Needles against him by saying that if he's sick, he must need injections, and she brings in a tray full of them. Stumpy claims to have gotten better and cleans the whole room within seconds.
  • Please Wake Up: In Episode 125, Quack Quack is shot with a bazooka and killed. Kaeloo desperately begs him to wake up and thinks the whole thing is a joke, but soon realizes that he is indeed dead. Later in the episode, we find out that he was faking it as part of a Batman Gambit.
  • Plot-Relevant Age-Up: In one episode Kaeloo finds out that Stumpy, who is ten, acts like a Kiddie Kid because his family stopped celebrating his birthday ever since he was five, which leaves him mentally stuck at the age of five. Kaeloo holds a "multibirthday" party to make up for the remaining five years, and since magic exists in Smileyland this somehow ages him up to the proper age. Unfortunately, the other guests at the party are excited to see the magic in action and keep celebrating more birthdays until Stumpy is aged up into a 30-year-old man. He's back to normal by the next episode.
  • Pokémon Speak: Quack Quack can only say his name, "Quack".
  • Poke the Poodle: In Episode 159, the gang are doing a roleplay game where Mr. Cat is the teacher and Kaeloo is the bad student who disrupts all the classes. Kaeloo's idea of being a "bad student" is doing things like writing in red ink instead of green and saying "I'm not here!" during attendance.
  • Polar Opposite Twins: Pretty and Eugly. The former is a Rich Bitch who treats others horribly while Eugly is more Spoiled Sweet and tends to be nice to people.
  • Police Brutality: Mr. Cat as a police officer in "Let's Play Cops and Robbers" is extremely harsh towards Quack Quack and repeatedly hits him for not confessing to a crime Quack Quack insists he had nothing to do with.
  • Politeness Judo: When Mr. Cat and Stumpy are vying for the last chair in a game of musical chairs, Mr. Cat says "after you" and offers the chair to Stumpy. Stumpy says "no, after you", and Mr. Cat accepts. Stumpy loses the game.
  • Polluted Wasteland: When Mr. Cat successfully takes over Smileyland in " Let's Play Me-Me-Nopoly", he takes steps to ensure that Smileyland turns into a polluted wasteland. Fortunately, Kaeloo is able to stop him.
  • "Pop!" Goes the Human:
    • Happens to Mr. Cat in one episode when he swells up after having an allergic reaction.
    • Happens to Stumpy in the Beach Episode. He incorrectly uses muscle-growth steroids, winds up getting inflated instead of getting muscular, and pops when trying to hit a volleyball.
  • Popular Is Dumb: Inverted. Mr. Cat and Pretty are apparently quite popular and well-liked by their peers and they're significantly smarter than the rest of the cast. Characters like Kaeloo and Stumpy, who are total morons, are perceived as weird and annoying.
  • Portal Door: The place is full of doors, and some of them lead to other dimensions.
  • Potty Emergency: Stumpy has one in Episode 85, but the bathroom is occupied. He then tries going in the bushes, but is stopped by Kaeloo. He finally solves it by stealing Kaeloo's hat and using it to do his business offscreen. And then Kaeloo, unaware of what just happened, puts the hat on her head.
  • Power Floats: Lavanade, who possesses a range of supernatural powers, is typically shown floating around rather than walking.
  • Power Incontinence: Lavanade has poor control over her supernatural powers, which leads her to cause bizarre events such as ghosts popping up wherever she goes. The problem gets even worse when she's upset, as her highly emotional state makes her completely lose control of her powers.

  • Promotion to Opening Titles: The first season had just the main four in the opening theme. In subsequent seasons new characters are added to the show, so all the recurring characters are added to the opening in the season they first appear.

    • In Episode 58, Mr. Cat goes on a game show hosted by Kaeloo. The final question in "What is Smileyland's number one rule?" He answers with "have fun", which turns out to be correct. Unfortunately, the others' idea of "fun" is tying him to a board and tormenting him.
    • In "What if We Played at Riding Ponies?", Stumpy and Quack Quack have a horse race against each other. Mr. Cat, who bet 6000 dollars on Stumpy winning, interferes with the race so Stumpy wins.

    • In Episode 112, it turns out that Stumpy, Quack Quack and Mr. Cat made a bet to see who could make Kaeloo get mad enough to beat them up first.

    • In Episode 85, Kaeloo and Mr. Cat have a debate over whether violently beating people up is a good thing or not. Kaeloo thinks violence is unnecessary, but Mr. Cat thinks they're fun. Mr. Cat wins the debate (by bribing Quack Quack, who was the judge, with yogurt), but since his argument was that violence is a good thing, she promptly punishes him with a No-Holds-Barred Beatdown so bad he can't even move for a while.
    • In Episode 135, the main four and the director can't agree on the show's budget; the director needs them to save money, which means they can't make their Les Misérables themed episode go as planned. They end up acquiring a bigger budget by getting Product Placement deals, which the director approves of, but they spend so much time promoting the products that it distracts from the plot anyway.

    Tropes Q-R 
  • Questioning Title?: The episode "What if We Played at Riding Ponies?"
  • Quicksand Sucks: One episode had Kaeloo, Stumpy, Quack Quack and Pretty try to find the ancient tomb of a pharaoh hidden in a desert. On their journey, Stumpy falls into a pit of quicksand and starts sinking. Of course, this being a show like Kaeloo, nobody cares. At least until he reminds them that he has their bag of supplies with him, after which they panic and rescue him.
  • Quirky Household: Stumpy and his sisters make up one of these. Stumpy is a complete moron, Ardoise is obsessed with money and spends all her time investing in stocks, Cramoisie is a bully, Lavanade has supernatural powers, Nombril spends all her time trying to get people's attention, Poucave is an aspiring journalist who writes her articles by spying on people with a Paper-Thin Disguise and learning their deepest secrets, and Violasse is cursed with terrible luck and keeps having to be rescued from bad situations.
  • The Quisling: In one episode, Quack-Quack wins a high-stakes game of Me-Me-Nopoly and becomes the King of Smileyland. While he doesn't really commit any atrocities against its residents, Kaeloo and Stumpy are still annoyed because Quack-Quack took the TV and the couch for himself. Mr. Cat decides to take advantage of the situation by becoming Quack-Quack's subservient personal advisor, using his authority as the king's personal adviser to enact laws that harm Kaeloo and Stumpy while benefitting him and Quack-Quack, and after he gains Quack-Quack's trust he tricks him into signing a legal contract that transfers his authority as king to Mr. Cat.
  • Rage Breaking Point: Mr. Cat (and occasionally Stumpy) will push Kaeloo past this point Once an Episode.
  • Raised by Wolves: Mr. Cat was apparently raised by a salmon who saved him after his horribly abusive family tried to drown him as a newborn kitten.
  • Rapid Aging: In Episode 191, Kaeloo finds out that Stumpy hasn't had a birthday party since he was five years old and throws him a "multibirthday" party to make up for all the lost years. Unfortunately, she overdoes it and somehow winds up turning him into an adult who keeps getting older.
  • Real Is Brown: The show had an episode where Kaeloo, freaking out about the idea of Moral Guardians telling her that the show is giving unrealistic expectations to children, tones down the show's cartooniness and makes everything realistic. The moment this is put into motion, the screen is covered with a brown filter to make it look dull and dreary.

  • Relationship Sabotage:
  • Relative Ridicule: Stumpy introduces his friends to his sister Lavanade, who has supernatural spirits and can talk to ghosts. Mr. Cat, who has also met a couple of other members of Stumpy's Quirky Household at this point, asks "is anyone in your family normal or are you all psychopaths?"
  • Removable Steering Wheel: In "Let's Play Driver's License", Quack Quack takes a driving test with Mr. Cat as the driving instructor.

  • Reset Button: See Negative Continuity above.
  • Resistant to Magic: Mr. Cat is immune to most forms of magic. The in-universe explanation for this is that magic only works on children because children believe in it; Mr. Cat is also a child and around the same age as the other characters, but due to his Dark and Troubled Past, he has "lost his inner child".
  • The Reveal: The penultimate episode of season 5 reveals that Mr. Cat's first name is Hector.
  • Rewatch Bonus: In several episodes, during serious and important scenes where emotions are running high, Stumpy interrupts by making jokes, which both the other characters and the viewers would attribute to him being The Ditz and not understanding the gravity of the situation. 234 episodes into the series, Cramoisie reveals that Stumpy intentionally makes stupid jokes when other people are sad or angry because he knows what's going on and he wants to lighten the mood and make them feel better, which recontextualizes these scenes in earlier episodes.

  • Right for the Wrong Reasons: In one of the season 4 episodes, Stumpy tells Kaeloo that his mother works two jobs, and Kaeloo assumes that he's lying to garner sympathy for himself. In Episode 236, which is in season 5, Kaeloo decides to ask Stumpy's little sister Poucave if this is true, and Poucave tells Kaeloo that this information is indeed false. Just as Kaeloo gleefully prepares to berate Stumpy for being a liar, Poucave clarifies, to her horror, that their mother doesn't work two jobs... she's a Struggling Single Mother who works three jobs.
  • Ring-Ring-CRUNCH!: In one episode, Mr. Cat smashes his alarm clock with a mallet when it rings.

    • Mr. Cat making three statements, with the third one being completely irrelevant to the other two.
  • Kaeloo being Driven to Madness by Mr. Cat and/or Stumpy's antics.
  • Running Gagged: In the first two seasons, a running gag was that nobody knew if Stumpy's long-distance girlfriend Ursula was real or not, and jokes would often rely on Ursula's existence being ambiguous. In Episode 116 from season 3, Stumpy's friends' questioning of Ursula's existence prompts Stumpy to have a mental breakdown, and in the hospital his friends encounter Ursula, who was real all along and has come to visit Stumpy. From this point onwards, nobody questions the existence of Ursula ever again.

  • Scare 'Em Straight: Parodied in Episode 96, when Stumpy and Quack Quack get addicted to eating carrots which have the same effect as tobacco.

And then they get addicted to something else.

  • Screw the Rules, I Have Money!:

  • Sdrawkcab Speech: In "Let's Play Paranormal Stuff", Kaeloo manages to get a spirit to communicate with them through Quack Quack. Its speech is incomprehensible at first, and when Stumpy asks why he can't understand it, Kaeloo explains that spirits always speak backwards and asks the director of the cartoon to play the snippet of dialogue backwards so that they can hear what it's saying.

    • During an earthquake, Kaeloo and Mr. Cat grab each other in a security cling that's more like a hug.
  • Self-Deprecation:

    Stumpy: I'm starting to get tired of the zombies, aren't you?
  • Sentry Gun: The entrance to several villain lairs is laced with these. Or worse, bazookas.
  • Serenade Your Lover: In one episode, Stumpy decides to ask Kaeloo to teach him how to attract girls, since she herself is a girl and probably knows what to do. She tries to teach him by making him dress as a girl and sit on a bench, so he will understand what a girl feels like. She then starts trying to serenade him with a song, pretending to be a boy, but he cuts her short because she's an awful singer and a Dreadful Musician.
  • Series Fauxnale: "Let's Play Bye Bye, Yoghurt" was intended to be the series finale, but the show was renewed for another season.

    Kaeloo (to Stumpy): Be serious, we're playing here!
  • Sesquipedalian Loquaciousness: Mr. Cat has the tendency to do this sometimes. Of course, nobody understands what he's talking about, since he's Surrounded by Idiots, so he ends up having to explain it in simpler terms.
  • Set Right What Once Went Wrong: In Episode 75, Kaeloo, Stumpy and Mr. Cat go back in time to the series pilot to prevent Quack Quack from ever getting addicted to yogurt. Unfortunately, Stumpy ignores a warning from Mr. Cat not to mess with the past, and he tells his past self everything about the future. When the gang return to the present, they find out that Stumpy is now the king of Smileyland.
  • Severed Head Sports: Happens a lot with Quack Quack's head. For example, in Episode 74, Mr. Cat kicks a soccer ball towards Quack Quack, the goalie, who blocks it. He then activates the bomb he had hidden inside the soccer ball, so Quack Quack's head is blown off, and Stumpy plays soccer with the head.
  • Sexy Cat Person: Ursula, if Kaeloo, Mr. Cat and especially Stumpy are anything to go by. Mr. Cat himself is this in Kaeloo's and Pretty's eyes.

    • Episode 94 revolves around Kaeloo trying to teach Stumpy and Quack Quack how difficult a parent's life is by role-playing for an entire day with them as her kids and her as their mom. She then spends the entire day going through all sorts of horrible things, like getting her car towed by Mr. Cat, getting stuck in traffic behind Mr. Cat and getting yelled at by her Mean Boss (also played by Mr. Cat). Finally, at the end of the day, Stumpy and Quack Quack have learned practically nothing because Kaeloo dropped them off at school in the morning, so they didn't get to watch what happened to her.
    • In Episode 83, Mr. Cat tries to ruin Kaeloo's Valentine's Day party as part of an elaborate scheme to get her to be his date. He successfully ruins the party by messing things up for all the other characters, but at this point Kaeloo is so mad by how things went down that she punches him instead of kissing him. So not only did Mr. Cat get his heart broken, everyone else went through a lot of suffering for nothing.
    • A minor example in the beginning of the episode "Let's Play Red Light, Green Light". Kaeloo tries to help Quack Quack open a container of yogurt. After she tries various methods to open it, she finally whacks it on the bottom, and the yogurt flies out and splatters all over a nearby rock.

  • She's a Man in Japan: The Italian dub, the Hindi dub, the Serbian dub and the first 10 episodes of the English dub turned Kaeloo male.
  • Shipper on Deck: Stumpy ships Kaeloo/Mr. Cat very, very hard. He even sets up a date for them in "Let's Play Babysitting".

  • Short-Distance Phone Call: In "The Thing From Outer Space", Kaeloo, Stumpy, and Quack-Quack use walkie-talkies to communicate with each other while playing a game of astronauts because they each think the others are far away, not realizing that they're mere feet away from each other.

  • Sick Episode: The episode "Let's Play Doctors and Nurses" had Stumpy fall sick and ask Kaeloo and Mr. Cat to help him. Of course, they callously ignore him and focus on giving medical treatment to Quack Quack, who is perfectly fine.

    • In Episode 108, Kaeloo tries to give Mr. Cat the silent treatment.

  • Silly Rabbit, Idealism Is for Kids!: Happens all too often with Mr. Cat and Kaeloo. Kaeloo's optimism is usually crushed when she gets a dose of the real world, with Mr. Cat telling her "I Told You So". One of the most prominent examples is the episode "TV News", where the characters start their own news channel. Mr. Cat says that the news needs "blood, pathos, and suffering" because that's what the viewers enjoy, but Kaeloo tells him that people aren't as bad as he thinks. The show's ratings go up when Stumpy and Quack-Quack beat themselves up on screen, proving that the viewers are indeed as horrible as Mr. Cat made them out to be, and the episode ends with Mr. Cat gently telling a crushed and heartbroken Kaeloo that people are the way they are and there's nothing he or Kaeloo can do to change that.
  • Silly Walk: Mr. Cat does this in "Let's Play Hot-Cold" while teaching Stumpy how to impress girls.

  • Skewed Priorities:
    • In the episode "Let's Play Red Light, Green Light", during a game of Red Light, Green Light, Mr. Cat fires a missile from a bazooka, and Quack Quack just stands in the path of the missile instead of running away like Kaeloo and Stumpy, because the rules of the game dictate that he shouldn't move.
    • "Let's Play TV News" suggests that Mr. Cat would prefer getting beaten up by Bad Kaeloo to losing TV ratings.
    • In the episode "Let's Play Market Vendors", Stumpy offers various gifts to anyone who is willing to buy apples from him, such as a magic hat with himself inside, and even a car, but he doesn't want to give away is his collection of comic books.

Stumpy refuses to help Quack Quack put the fire out until he teaches him the trick, because learning a new trick is clearly more important than saving your friend who is on fire.
    • When there is a power outage, the fridge stops working. Quack Quack is worried that the food inside might get spoiled. What does he do?

It's perfectly fine to electrocute your friend as long as your food doesn't rot.
    • In Episode 232, Stumpy introduces his friends to his sister Violasse, who was Born Unlucky. Violasse falls into an interdimensional portal and Stumpy screams "Violasse!" in horror. Rather than worry about his friend's sister falling into a portal, Mr. Cat more concerned by the fact that a parent would give their child a ridiculous name like Violasse.note  In the same episode, Stumpy goes to rescue Violasse, and his main motivation isn't that he's worried about never seeing his sister again, but rather that he's worried that his mom would be mad at him for losing her.

  • Social Services Does Not Exist: The main characters live in Smileyland, a place that's inhabited exclusively by kids. Kaeloo is a child with no parents (that we know of). Quack-Quack is an orphan who is being raised by Kaeloo, despite the fact that Kaeloo is also a child. Mr. Cat, also a child, ran away from his abusive family and is now living by himself. Despite all of this, social services have not intervened. To make matters even more confusing, Kaeloo's extended family knows where she lives but nobody cares that she lives alone, and Mr. Cat's mother lives within driving distance of where he currently lives. The only time when social services are brought up are when Mr. Cat tells Stumpy and Quack-Quack a Fractured Fairytale version of Cinderella where the moral is "if your parents are abusing you, call the police on them", and even in his story when the stepmother gets arrested for child abuse, the police just let young Cinderella live by herself with no adult supervision.

  • Sound-Effect Bleep:
    • In "Let's Play Peace Man", Mr. Cat drops what seems to be a Cluster F-Bomb over a microphone, but the microphone keeps malfunctioning. Given Kaeloo and Quack Quack's horrified reactions, it's safe to assume that even if the audience didn't hear anything, they did.
    • When Mr. Cat mentions the name of an alcoholic beverage on Episode 87, it's bleeped out with the sound of a rubber ducky. This was most likely done for laughs since Stumpy then proceeds to say a long string of names of alcoholic drinks and there's no bleep.
  • Space Episode: The episode "Let's Play Astronauts" had the main four go to outer space to find a star so Stumpy could name it after his girlfriend to celebrate their two-week anniversary. The events of the episode turn out to be All Just a Dream.

Kaeloo manages to pull numerous objects out of a hat while Mr. Cat boos her for perfomring cliched tricks. Stumpy's act fails because he didn't have a trick and thought magic was real. Mr. Cat gets Quack Quack to be his assistant and saws him in half for real.
  • Stalking Is Funny if It Is Female After Male: It would probably be less funny and more creepy if Mr. Cat was the one stalking Pretty.
  • Standing in the Hall: Stumpy tries to get Kaeloo, who is pretending to be a Stern Teacher, to give him this punishment or send him home in "Let's Play Teachers" after he is forced to play a school-themed game. She decides to make him write lines instead.
  • Stay in the Kitchen: In Episode 130, Mr. Cat says that he believes that girls and women should cook and do housework. He puts a bow and an apron on Kaeloo, makes her stand in the kitchen and asks her to cook something while he sits on the couch and watches sports on TV. Kaeloo doesn't take this very well - she winds up Hulking Out and then chasing him around with the frying pan.

    • In Episode 83, Mr. Cat decides to lie to Quack Quack to ruin his relationship with Eugly, and he slithers onto the couch on his belly instead of walking towards it. He was being a literal snake.
    • One episode shows Quack Quack and Eugly playing badminton with Olaf as the birdie. Olaf is a penguin, making him a literal "birdie".

  • Street Musician: In Episode 128, while trying to raise money to buy himself a new video game, Stumpy plays music while Kaeloo and Quack Quack are on the subway. As one would expect, he's an absolutely Dreadful Musician. Since Kaeloo already gave him money on three separate occasions in that episode, she initially refuses to pay him, but he threatens to keep playing if she doesn't, so she reluctantly gives him more money.
  • Strictly Formula: The first season went mostly like this: Kaeloo suggests a game, Mr. Cat tortures Quack Quack during said game, Kaeloo transforms into a giant monster and beats up Mr. Cat, and Stumpy does something stupid along the way. Lampshaded in the first season finale, which was ironically just before the show stopped being formulaic.
  • Stuff Blowing Up: Given the fact that the characters have bazookas, missiles and bombs, this trope happens at least Once an Episode.
  • Stunned Silence: Mr. Cat's response when one of the others does something that can be considered stupid even for their standards is normally to stare at them in complete silence.
  • Stylistic Self-Parody:
  • Stylistic Suck: In Episode 105, Kaeloo introduces all the characters in the style of moving drawings on a sheet of ruled paper, and her drawing of Stumpy is absolutely terrible. Lampshaded by Stumpy himself.
  • Subways Suck: In Episode 94, Kaeloo goes around the typical work day of an adult, with Mr. Cat following her around to each location to find new ways to troll her. After Mr. Cat tows her car, Kaeloo takes the subway, only to find that Mr. Cat is on the subway too, and he takes the opportunity to sing loudly and obnoxiously while playing music on a boombox knowing that Kaeloo can't do anything to stop him because it's a public space.
  • Sudden Anatomy:
  • Sudden Downer Ending:
    • In Episode 118, when the Alpha Bitch Pretty posts humiliating pictures of Kaeloo, Stumpy, Quack Quack and Mr. Cat on social networking site "Fakebook", they get revenge on her, and then the fight escalates until the four of them use Disproportionate Retribution to punish her. At the end of the episode, they decide that they were too harsh and go to apologize and give her some presents, but before they can, they find out that she wrote a book revealing all of their embarrassing secrets and already published two million copies. They decide to leave without saying anything and accept that they'll never change her.
    • In Episode 124, Kaeloo, Stumpy and Quack Quack play a new game that uses technology which requires an immense amount of concentration. The episode goes well and they have fun together, but at the very end of the episode, since Stumpy doesn't have much in the way of a brain, concentrating proves to be too much for him and he has to go to the hospital, and ends up flatliningnote . Of course, this being Kaeloo, nobody cares, but it still is pretty sad.
    • In Episode 16, the episode has a generally funny plot, but at the end, Mr. Cat, Stumpy and Quack Quack decide that Kaeloo has gone too far and decide to kick her out of Smileyland. The episode ends with Kaeloo's friends kicking her out.
    • A pirate themed two-part episode had Olaf send the main four on a dangerous treasure hunt and promise that he would reward them if they found the treasure.

  • Suddenly Shouting:
    • Mr. Cat does this in "Let's Play Scaredy Cat" when he finds out that the others are playing his favorite game, "Scaredy Cat", without him.
    Mr. Cat (to Kaeloo): So, I hear you're playing Scaredy Cat without me... WHEN IT'S MY FAVORITE GAME!
    • He also did it in "Let's Play Danger Island Survivor" after finding out that the last challenge of Kaeloo's game consists of avoiding cute little sheep.
    Mr. Cat: *imitating Kaeloo* Nice little sheepie-weepies, hehe... HAVE YOU BEEN SMOKING CANDY WEED?! TELL ME WHERE THE DANGER IS HERE!

    Olaf: All of you... ARE FIRED!
    • Stumpy does it very very often, almost Once per Episode. For example, in one episode, where he has the flu but Kaeloo and Mr. Cat decide to give a check-up to Quack Quack (who is perfectly fine).
    Stumpy: Could you please speed things up a bit? Because my flu is DRIVING ME NUTS!
  • Suddenly Speaking: For the first three seasons, the sheep were just regular sheep that couldn't talk and served as little more than props. Starting from season 4, the sheep are capable of speech and are Funny Animals like the other characters.

  • Suicide as Comedy: A Running Gag is to have Stumpy attempt suicide and fail hilariously.
    • In one episode, Mr. Cat gets so fed up of Stumpy's stupidity that he hangs himself. Of course, since Death Is a Slap on the Wrist, he's perfectly fine by the very next scene.
    • In Episode 215, Mr. Cat convinces everyone in Smileyland except Kaeloo that the end of the world is coming, causing several people to kill themselves to save themselves from the oncoming apocalypse.
  • Superhero Episode: "Let's Play Justice Masters".
  • Superpowers For A Day: If anyone gets superpowers, they're likely to lose them by the end of the episode.
  • Super Zeroes: Ratman is an atrociously bad superhero who somehow manages to make things even worse by attempting to save the day due to a combination of bad luck and sheer stupidity. In one episode a news reporter even mentions that the city's crime rate went up by 400% thanks to Ratman's incompetence.
  • Sure, Let's Go with That: In one episode, Mr. Cat makes a Love Confession to Kaeloo. Unfortunately, she thinks he's making a joke in bad taste. In order to avoid being rejected, or worse, he quickly decides to pretend that it was indeed a joke.
  • Surreal Humor: Of course, it should be expected from a show about Funny Animals living on a planet full of magic. Weird things happen, involving stuff like aliens, weapons, explosions, interdimensional travel, etc.
  • Suspiciously Similar Substitute: With Pretty having undergone a Heel–Face Turn off-screen prior to Season 5, Stumpy's sister (who was introduced in the same season) Cramoisie has essentially become the new Pretty; she's rude, bullying, manipulative, abusive to her Butt-Monkey sister, often a Karma Houdini, and (understandably), none of the main cast like her.
  • Suspiciously Specific Denial: In the tea party episode, everybody except Stumpy is given electric shocks all of a sudden while Stumpy just sits at the table laughing. Mr. Cat glares at Stumpy, prompting this response from him:

  • Sweeping Ashes: Happens to Quack Quack twice, courtesy of Mr. Cat's science experiments.
  • Swiss-Army Appendage: Not only do the alien sheep have weapons for limbs, they can replace them with other weapons.

    • Stumpy somewhat manages to do this by the end of Episode 105.
  • Take That!:
    • Episode 64 had Mr. Cat open up a fast-food restaurant which served actual trash from the dumpster as food. When everybody else starts protesting against this, he offers them toys with their "food". Everyone immediately stops protesting and buys more food for the sake of the toys.
    • In another episode, when Kaeloo and Mr. Cat are playing a game where the object of the game is to make another person laugh, Kaeloo stands on a podium pretending to be a politician, makes a lot of promises and says she will keep all of those promises. Mr. Cat bursts out laughing.
    • In one of the season 1 episodes, Stumpy is selling apples, and his apples are horribly rotten. When Mr. Cat points out that the apples are rotten, Stumpy replies "No, they're organic."
    • In Episode 135, around a minute into the episode the show's director tells the main four that they've gone over the animation budget for that episode. After lamenting that money is being prioritized over artistic creativity, the main four remove the special effects, the backgrounds, all the props, and the script itself, leaving literally nothing for the episode. Later in the episode, they get the chance to increase the budget by doing Product Placement for a sausage manufacturing company, but get so carried away with promoting the product that the rest of the episode is essentially a glorified sausage commercial.
    • Also in Episode 135, the main four try to make their own episode using figurines of themselves and a video camera. The video turns out poorly made. Mr. Cat says that the episode they made was incomprehensible, "like a Danish movie".
    • Then there's this little exchange between Kaeloo and Mr. Cat in an episode where they're both doctors in a hospital:
    Mr. Cat (referring to Quack Quack, who is the patient): I'm gonna book him in for surgery, but, before that... (starts throwing papers around) scanners, MRAs, X-rays, colonoscopies, the whole nine yards, muahahahaha!
    Kaeloo: Is all that really necessary, Mr. Cat?
    • In one episode, the characters participate on a parody of The Voice. Kaeloo, who is the only female contestant, decides that the best way to win is to perform a sexually suggestive dance wearing an inappropriate outfit. After watching it, Pretty, who is one of the judges, grabs a mic, faces the camera, and criticizes Kaeloo's performance for how she just portrayed females and says that there's more to girls than that, which is a jab at how many female singers tend to sexualize themselves to get attention.
    • In Episode 68, the gang decide to play rock music. Mr. Cat picks up a microphone and screams into it. No words, just screaming. This is then posted on the internet and becomes an Instant Web Hit.
    • One of the season 3 episodes had a few of the characters compete in an election to become the president of Smileyland. Mr. Cat's campaign is full of lies and fake promises... and he's dressed like President Donald Trump.
    • Episode 138 had Mr. Cat attempt to diagnose Stumpy with dyspraxia even though it's obvious that he doesn't have dyspraxia and is just lazy. The episode is meant to be a satire on psychologists who diagnose normal kids with illnesses and then try to treat them for those illnesses.
    • The episode Art Class was dedicated to making fun of modern art. Highlights include Mr. Cat explaining that you can put any mundane object on a pedestal and call it art, and Stumpy sitting on a toilet, taking a shit and calling it "performance art".
    • Episode 59 calls out judges who are biased and unfair. In this case, Olaf, the judge in a cooking contest, declares Mr. Cat the winner without even tasting his dish just because the dish was something from his homeland, and he also disqualifies Eugly from the competition for "being ugly", which has nothing to do with her ability to cook. The same episode manages to get a shot at new "health" fads by having a scene where Pretty serves up a dish of live earthworms, claiming that they're a new type of health food.
    • The entirety of Episode 112 is one big Take That! at capitalism. Mr. Cat starts a business where he "motivates" his employees by threatening them with bazookas, gives them breaks that are literally only a few seconds long, and yells at everyone for trivial reasons.
    • In "Let's Play Figurines", Mr. Cat attempts to file a complaint so that he can sue a company, but the administrative process is so slow that every time he calls, he gets sent to voicemail.
    • In Episode 194, the characters talk to the audience about what life is like as a cartoon character. Stumpy attempts to tell the audience that he is a symbol of a generation of young people in danger and tries to talk about his passions, only for Kaeloo to cut him off and say that the most important part is that he's "the idiot", much like a viewer who only looks for one quality in a character and refuses to see any other, deeper aspects of that particular character and their development.
    • In season 5 the writers were forced to tone down the adult humor of the series and voiced their displeasure through Episode 226, where they mock censorship. In this episode, Kaeloo must show the show's producer a montage of clips from previous episodes to gain his approval for a sixth season, and is told by Rules that her chances of success will improve if she shows the producer G-rated content that's "just like every other kids' show", and Kaeloo goes overboard with censoring her montage, such as cutting out gentle slapstick comedy because it supposedly has the potential to severely traumatize kids. The producer shows the montage to his child, an in-universe fan of the series, and the kid sadly asks his dad why the show sucks now, with the producer agreeing that it's lost its uniqueness.
  • Take That, Audience!:
    • In "Let's Play Once Upon a Time", Stumpy suggests making a kids' show about a frog who transforms into a giant monster when she's angry. Mr. Cat's response?
    Mr. Cat: Who in their right mind would watch crap like that?
    • In another episode, the main four make their own TV show and it's clearly a parody of the actual show. It makes no sense to anyone and everyone hates it except Stumpy, the resident moron. Stumpy also mentions that the only reason he liked it was shipping the characters in their show who were supposed to be based on Mr. Cat and Kaeloo, a reference to how many fans ship those two and focus exclusively on their relationship instead of the other aspects of the shownote .
    • In the finale of season 4, the characters painstakingly explain to the audience how an episode of a cartoon is made by walking them through the process. The audience demands to know when they can see new episodes and Kaeloo explains that, as they just saw, it takes a very long time to make episodes, they may have to wait a while for the show's fifth season. The audience instantly turns against the characters and starts pelting them with trash because they want a new episode right this instant, not unlike the fans who constantly complain about the hiatuses between seasons being too longnote .
  • Taking the Bullet: Quack Quack jumps in front of a barrage of sharp objects before they can hit and kill the rest of the main four in Episode 92. Mr. Cat calls him a show off.
  • The Talk: Kaeloo tries to give Stumpy the Talk, but he interrupts her with his attempts to not breathe (as Mr. Cat had given him a fake version of the Talk telling him that to make a baby, you had to avoid breathing for two days).

    • In Episode 55, Mr. Cat, who is having a headache, takes an aspirin and lies on the couch saying that with absolute silence he should be fine. As soon as he says that, Stumpy and Quack Quack show up and start making noise.
    • In the first episode, "Let's Play Prison-Ball", the gang are playing prison-ballnote . Stumpy sings "You'll never hit me! You'll never hit me!" and Quack Quack promptly hits him with the ball.

    • In Episode 3, the main four are playing "Red Light, Green Light", and after repeatedly injuring Quack Quack in various ways, Mr. Cat cheats and wins the first round. Kaeloo says that at least he won't be able to hurt Quack Quack during the second round of the game, but is proven wrong as he is able to hurt Quack Quack even worse than before.
    • In Episode 134, Mr. Cat is driving his car and remarks on how relaxing it is. Just then, Stumpy and several clones of himself, who are angry at Mr. Cat, drive up in several more cars and crash all their cars into his.
    • In Episode 118, Stumpy says he'd "sooner be hit by a car full of sheep" than appear in one of Pretty's photos. The moment he finishes speaking, he gets hit by a car full of sheep, and Pretty takes a picture of this.
    • In Episode 129, everyone tries to stay up late at night to see a shooting star.
    Kaeloo: I can stay up all the way until ten o'clock!
    looks at clock
    Kaeloo: Oh, it's ten o'clock!
    Kaeloo falls asleep
    • In one episode, the characters play "waiter race", a race where everyone dresses up as a waiter and has to carry a tray full of objects while running to the finish line. Inches away from the finish line, she remembers that the race was set up by Mr. Cat and remarks to the audience that it's odd that nothing bad has happened. Immediately, a bunch of traps are sprung, causing Kaeloo to lose her balance and drop the tray, disqualifying her from the race.

  • Terrible Interviewees Montage: In Episode 121, Kaeloo, Stumpy, Quack Quack and Mr. Cat are informed that they have been fired from the show and have to take a job interview with Olaf to get their jobs back. In the montage, Kaeloo doesn't know how to answer the questions and randomly uses words in the hopes of making what sounds like an answer, Stumpy repeatedly says that he's the show's funniest character and has random objects drop onto his head from the sky to prove it, Quack Quack uses complex math equations and Mr. Cat resorts to telling Blatant Lies, bribery and using random words. They all get re-hired anyway, because they were never actually fired, it was just a "joke" that Olaf was playing on them.
  • Tertiary Sexual Characteristics: Averted with Kaeloo, who has no features to distinguish her from the males, while other females are drawn with breasts and/or curves, and eyelashes. Played straight in the games the gang play, where they often use fake mustaches, bows, etc.

  • Theme Tune Roll Call: The theme song introduces all the characters, although it has no lyrics. It shows everyone with their names doing something they'd normally be doing (such as Quack Quack eating yogurt and Pretty using her phone).
  • Theme Twin Naming: Inverted with Pretty and Eugly, whose names have opposite meanings.
  • There Are No Adults: Adults (and teenagers) aren't allowed in Smileyland.
  • There Are Two Kinds of People in the World: This quote from the episode "Let's Play Gangster Poker":
    Stumpy: In this world, there's two kinds of people. Those who have a banana, and those who dig. You dig.
  • There Is a God!: In one episode, Mr. Cat prepares to attack Stumpy with a chainsaw, but is suddenly struck by lightning, causing Stumpy to remark "God exists!" Stumpy himself is hit by another lightning strike and adds "... or not!"
  • There Is Only One Bed: In Episode 106, Mr. Cat buys too much stuff at a Garage Sale from Kaeloo, Stumpy and Quack Quack, so his bedroom gets too full and he can't get inside. He tries to invoke this trope by breaking into Kaeloo's bedroom and trying to sleep next to her, but it's subverted when she makes him sleep on the couch instead, to his disappointment.
  • Thermometer Gag:
    • Mr. Cat pulls out a giant thermometer and decides to use it on Quack Quack in "Let's Play Doctors and Nurses". He never gets the chance, though, since Kaeloo transforms and Quack Quack takes the opportunity to escape.
    • In another episode, Kaeloo eats a bag of chips which Mr. Cat sold to her as a scam, and they give her a stomach ache. Mr. Cat, who is also pretending to be a doctor as part of another scam, shows up to cure her stomach ache and tries to take her temperature. She punches him before he can actually do it.
  • They Killed Kenny Again: See Negative Continuity above.
  • Thicker Than Water: Pretty may be mean to Eugly, but she's even willing to chew out Mr. Cat, her crush, if he insults her sister.
  • Think of the Censors!: Kaeloo constantly reminds her friends that they are on TV and are being watched by children, and that the viewers' parents or the censor board might get mad at them.
  • This Banana is Armed: Quite literally; at least a couple of episodes have the characters use bananas in place of actual guns.
  • This Is Gonna Suck: Mr. Cat's reaction to Kaeloo Hulking Out for the second time in "Let's Play Prison-Ball" is to put on an annoyed facial expression which pretty much says "Do I really need to put up with this?".
  • This Is Unforgivable!: In the season 3 premiere, Planet Smileyland gets destroyed and any person has the ability to recreate it the way they want. The gang sends Quack Quack to recreate it exactly the way it was, but it ends up becoming a planet where a) everything is made of yogurt, including everyone's precious personal possessions, and b) Stumpy's girlfriend, Ursula, becomes an unperson since Quack Quack doesn't know her. Kaeloo says she will never forgive Quack Quack. Subverted since he manages to fix everything and Kaeloo tells him that his actions have been Forgiven, but Not Forgotten.
  • Thousand-Yard Stare: A mild example. After Kaeloo forcibly kisses Mr. Cat in the episode "Let's Play Peace Man", he sits under a tree and stares into the distance. A few minutes later, he recovers after she asks him if they can do it again.
  • Throw the Book at Them: In Episode 9, Mr. Cat (acting as a Dirty Cop) attempts to torture a confession out of Quack-Quack for a crime he didn't commit by repeatedly whacking him over the head with a book. Kaeloo brings in a book with Smileyland's laws to read out to Mr. Cat that Quack-Quack has the right to an attorney, but Mr. Cat realizes that her book is bigger and uses it to hit Quack-Quack instead of the one he was using before.
  • Tightrope Walking: In the Circus Episode, Quack Quack, who is known in-universe for doing things that are Beyond the Impossible, manages to do this without a rope to walk on, by balancing on thin air. The act is called "Tightrope walking without a tightrope".
  • Time-Compression Montage: In Episode 234, Kaeloo, Stumpy, and Pretty, encouraged by Mr. Cat, play a cruel prank on Rules which sends her into a state of depression. A montage is then shown of Rules sitting sadly on the ground and ignoring everything around her while the other characters do their own thing, ranging from mundane (such as the main four having a snowball fight) to extreme (such as a full-scale alien invasion of Smileyland).
  • Time Machine: Mr. Cat has one, which he got from a store. The main four use it to travel back and forth in time.
  • Time-Passage Beard: Parodied. Stumpy, who is a kid, somehow grows a gray beard after being stranded on an island for less than a day. So does Kaeloo, who is also a kid... and female.
  • Time Travel Episode: The episodes "Let's Play Time Travel", Episode 75 and Episode 76note .
  • Tiny Guy, Huge Girl: Eugly is nearly twice Quack Quack's size.
  • Tongue Trauma: In Episode 119, Mr. Cat threatens to rip out Stumpy's tongue to prevent him from telling Kaeloo a secret, but settles for just stretching it out as far as it will go and then having a sheep lick it.
  • Tongue-Out Insult: In Episode 241, Stumpy and his little sisters hold hands to cross the street, and out of all his sisters, Stumpy chooses to hold hands with Violasse. Violasse, who is quite possessive of Stumpy, sticks her tongue out at the other sisters, who stick their tongues back out at her.
  • Too Hungryto Be Polite: Stumpy usually isn't very polite, but he'll be even less polite if you set a plate of food in front of him, especially when he's hungry.
  • The Tooth Hurts: Stumpy spends the entirety of Episode 131 with a toothache. At the end, Serguei punches him, sending him flying, and he crashes into a tree, making his front teeth fall out.
  • Toothy Bird: Olaf the penguin has visible teeth; depending on the episode, Quack Quack may have them as well.
  • Toxic Friend Influence: Mr. Cat is a horrible influence on Stumpy and often teaches him that doing bad things is a good idea, like annoying a teacher to get kicked out of class or robbing a supermarket. Kaeloo tries her best to stop Stumpy from listening to Mr. Cat, but it usually doesn't work.
  • Trademark Favorite Food: Quack Quack has yogurt and Stumpy has nuts. Stumpy also seems to like paninis in the French dub and hot dogs in the English dub.
  • Tradesnarkâ„¢: "Time Machine Expressâ„¢", a company that sells time machines.
  • Trampoline Tummy: Mr. Cat isn't fat, but that doesn't stop Bad Kaeloo from doing this to him anyway.
  • Transformation Sequence: Kaeloo goes through one Once an Episode. Oddly, it's been shown that she can turn into Bad Kaeloo near-instantly.
  • Translation: "Yes": A single "quack" from Quack Quack can narrate a story that takes 20 seconds to narrate in English.
  • Translator Buddy: In early episodes, Kaeloo was one to Quack Quack. In later episodes, everyone can understand what he says.
  • Trapped in Another World: Happens to Kaeloo in Episode 70, since Mr. Cat accidentally throws her through the Portal Door after mistaking her for her Alternate Universe counterpart and then smashes the door.
  • Trapped in the Past: Happens to Mr. Cat at the end of Episode 75. The rest of the main four travel back in time to rescue him in Episode 76.
  • Trash of the Titans:
    • Mr. Cat, Quack Quack and especially Stumpy create huge piles of trash.
    • Stumpy's bedroom is full of trash, such as old food lying on the floor and empty soda cans everywhere, and as a result it smells awful too.
  • Trauma Button: If anyone mentions dead parents in any way, shape, or form, Quack Quack, whose parents were brutally murdered, will go into Troubled Fetal Position and rock back and forth.
  • Troperiffic: The series is a Deconstructive Parody of children's shows where Kaeloo acts like a normal children's show character and everybody else questions her sanity, and thus it spoofs a lot of tropes, often related to the genre it's focused on.
  • Troubled Backstory Flashback:
    • Mr. Cat has given a few of these, but not his entire past at once.
    • Episode 104 has a flashback that reveals Olaf's backstory, narrated by Olaf to Kaeloo and Mr. Cat, in which he was exiled from the ice caps by his fellow emperor penguins and left to drift at sea for days on a piece of ice before finally washing ashore at Smileyland.
  • Troubled Fetal Position: Quack Quack assumes this position and starts rocking back and forth whenever somebody mentions the death of fictional character Happy Rotter's parents.
  • Troubling Unchildlike Behavior: Mr. Cat is a psychopath who owns weapons (and is not afraid to use them), has tried to have sex, is alcoholic, and is a preteen.
  • Trouser Space: Quack Quack can store anything in his underwear (he doesn't wear pants), from baseball bats to apples.
  • True Art Is Angsty: Parodied: in Let's Play Art Class, Mr Cat lampshades this trope as an excuse to blow Quack-Quack's head with a bazooka in a "performance". Right after, Stumpy takes the bazooka and blows his own head for posterity.
  • True Art Is Incomprehensible: The Let's Play Art Class episode is a big Take That! against this.
    Mr. Cat: This is a mere yoghurt. But place it on a pedestal, and add a signature, and it becomes art.
  • True Companions: The main four. They are very close and have even been referred to as a sort of "family" by others.
    • One episode even had them rap about them going to Hell together (Kaeloo for getting angry, Stumpy for being a "phoney", Quack Quack for being greedy and Mr. Cat for obvious reasons).
    Kaeloo [rapping]: Eternity isn't long when you are not alone!
  • Truth Serum: All four main characters get injected with this in "Let's Play Spies".
  • Twinkle in the Sky: If Bad Kaeloo or Serguei throws someone into the air, expect this to happen.
  • Twinkle Smile: In "Let's Play Air Pockets", Mr. Cat smiles and his mouth shows a twinkle, complete with an Audible Gleam.
  • Twitchy Eye: Happens to Mr. Cat a lot, usually when someone does something really dumb.
  • Two Lines, No Waiting: Episode 86 had two plots: one where Kaeloo forces Mr. Cat to see a psychotherapist and another where the rest of the cast get into a fight.

    Tropes U-Z 
  • Understatement: In one episode, Mr. Cat mentions giving Quack Quack a "little" electric shock. When he actually administers it, Quack Quack is reduced to Sweeping Ashes and Kaeloo angrily reminds him that he said it would only be a small one.
  • Unexpectedly Dark Episode:
    • Episode 204 starts with the main four having a fun snowball fight together, and Kaeloo and Stumpy note that Mr. Cat is a Defrosting Ice King and he's acting much nicer than he used to. They mention this to Mr. Cat, who starts freaking out and having an identity crisis because he perceives the meanness as a core part of his identity. He spends the rest of the episode traumadumping to Quack-Quack about how his Dark and Troubled Past shaped him into the person he is today, explains that his cruelty is caused by a desire to appear stronger and not be bullied himself, and laments the fact that he was constantly forced to fend for himself throughout his childhood and became the wise and mature person he is today because he's jealous of how other children his age can be so carefree and happy.
    • Episode 236 involves Kaeloo forcing Stumpy to participate in a televised talk show, with his little sisters present to debunk any lies he may tell. The episode starts off comedic but takes a darker turn when Kaeloo starts asking about Stumpy's family. The sisters reveal that their father was an alcoholic who ran out on them and due to the large size of their family, their mother had to take up three jobs to support them all, and even then they continue to live in poverty, but they try to stay happy by reminding themselves that there are other people out there who have it worse than them.
    • The episode "Let's Play Trap-Trap". It starts off with a seemingly normal plot where Kaeloo, Stumpy, Quack Quack and Mr. Cat play a nice game of Trap-Trap, with the beginning being so sweet that Kaeloo even gives Mr. Cat a hug. Then, halfway through the episode, Quack Quack goes insane and tries to cannibalize Kaeloo and Stumpy, and successfully eats half of Kaeloo's brain, leaving her unintelligible, and Mr. Cat has to step in and save the day.
  • Unexplained Accent: Olaf has a Russian accent despite being from Smileyland's equivalent of Antarctica.
  • Unexplained Recovery: See Negative Continuity above.
  • Unfortunate Names: Stumpy and his seven sisters have ridiculous-sounding names that are made fun of by the other characters.
  • Ungrateful Bastard:
    • Mr. Cat in "Let's Play Goodbye, Mr. Cat!". His friends try to help him out and he repays them by beating them all up near the end of the episode.
    • In Episode 92, after Quack Quack saves Kaeloo, Stumpy and Mr. Cat from being impaled with sharp objects and then crushed to death by jumping in front of them, Mr. Cat's response is to call him a show-off. Yes, really.
    • Stumpy is one to Kaeloo in Episode 128. The plot of the episode revolves around Stumpy using various schemes to trick people into giving him money to buy a video game. Each time he tries something on Kaeloo, she immediately sees through the trick, but gives him money anyway and compliments his creativity in coming upnwith the scheme. In order to get more sympathy from others and therefore more money, Stumpy goes on TV and narrates a completely false story about his life which portrays Kaeloo as a selfish and bossy jerkass.
  • The Unintelligible:
    • Zigzagged with Quack Quack, who speaks entirely in quacks. Sometimes everyone understands him, sometimes they don't.
    • Eugly speaks entirely in whispers, mumbles and sign language.
  • Unishment: In the episode "Let's Play Teachers", Kaeloo warns Stumpy that he will get kicked out of class if he misbehaves. Mr. Cat notes that only a teacher would think that was a punishment, and Stumpy spends the rest of the episode misbehaving so he can get kicked out. It fails because she decides to make him write lines instead.
  • Unperson: Happens to Ursula in Episode 105, but this is thankfully fixed. Also almost happens to Kaeloo, Quack Quack and Mr. Cat in the same episode, thanks to an angry Stumpy wanting payback for the way they always treat him.
  • Unprovoked Pervert Payback: A Rare Male Example. Mr. Cat hits Stumpy with a baseball bat just for being outside the door when he was in the bathroom and accuses him of voyeurism.
  • Unreliable Narrator:
    • In seasons 1 and 2 of the show, Stumpy would complain about how he never knew what his mother did all day while he was at school and that she was neglectful and never spent much time with him. Later episodes in the show reveal that Stumpy's mother is a hardworking single mother of eight children whose only reason for not spending time with him is that she works three jobs to earn enough money for her family.
    • In seasons 1-4, Mr. Cat had an established backstory in which he ran away from home to escape his abusive family, consisting of an alcoholic father, a mother who always screamed at him, and two older brothers who bullied him. However, he kept saying things that [[Multiple-Choice Past conflicted with his established backstory. Season 5 explains that this was actually due to him deliberately telling lies about his past, and the established backstory was the only true one.
  • Unrequited Love Switcheroo: Happens on a regular basis between Kaeloo and Mr. Cat. Who's crushing on whom depends on the episode, and in some instances, the switcheroo happens within the same episode.
  • Unresolved Sexual Tension: The relationship between Kaeloo and Mr. Cat. It's obvious that the two of them are attracted to each other, and even Stumpy has figured it out.
  • Unsportsmanlike Gloating: If Mr. Cat ever wins anything, the first thing he does is yell "I WON!" and make fun of the loser(s) of the game. An example is in Episode 85 where he wins a debate against Kaeloo (by cheating), and his response is to jump up from the table, throw a mallet at Kaeloo, and run around yelling about how he won.
  • Unstoppable Rage: Once Bad Kaeloo gets mad at Mr. Cat, there's no stopping her, and she will destroy anything standing in her way.
  • Unusual Euphemism: The trope is parodied. In one episode, Mr. Cat offers to take Kaeloo on a dinner date and implies that they can have sex afterwards using a euphemism about "accountants" and "checks". Kaeloo, being naïve and innocent, believes that he's trying to bribe her.
  • Unusually Uninteresting Sight: In one episode, Pretty attempts to make Mr. Cat fall in love with her using a Love Potion, which she disguises as a soda by pouring it into a soda can. When Mr. Cat drinks it, he ends up falling in love with the soda can instead. Nobody bats an eye at this, with the other characters expressing that they're happy that Mr. Cat was able to find love. The only person who finds this odd is Kaeloo, and even her opposition to this is mostly out of jealousy over Mr. Cat being in a relationship with the can rather than the relationship being weird.
  • Unwanted Assistance: All of Kaeloo, Stumpy and Quack Quack's attempts to help Mr. Cat relax in "Let's Play Justice Masters" wind up stressing the poor cat even more.
  • Unwitting Instigator of Doom:
    • Stumpy is one in the episode "Let's Play the Quest for the Wholly Gruel". He finds the titular Wholly Gruel, a magic crayon which can make anything it draws real, and uses it to doodle all over some hieroglyphics in a cave depicting characters who resemble him and his friends. He draws a meteorite about to strike them, and his real friends, meanwhile, almost get hit by an actual meteorite.
    • In Episode 215, a random guy runs past the main four while screaming "it's coming!" in a panicked voice. Mr. Cat, who tends to see the worst in everything, is convinced that something bad is going to happen. Things escalate, and then Mr. Cat convinces everyone else in Smileyland that the end of the world is coming, leading to mass panic which causes fires, property damage, and several background characters being Driven to Suicide. At the end of the episode, it's revealed that the guy from earlier was just having a Potty Emergency and there is no apocalypse coming.
  • Uptight Loves Wild: Uptight, stuffy Kaeloo and resident bad boy Mr. Cat who couldn't care less about the rules.
  • Use Your Head:
    • In the episode "Let's Play Red Light, Green Light", Stumpy tries to cut a tree by ramming into it with his head. He fails.
    • In Episode 93, when Stumpy and Quack Quack are training to be firefighters, their practice involves "saving" Mr. Cat from a building with fake flames. Stumpy tries to break down the door by using Quack Quack's head as a battering ram. It doesn't work, so Kaeloo tells them to use the ladder to get to the window Mr. Cat is at. Stumpy then tries to smash the windowsill while continuing to use Quack Quack's head as a battering ram instead of just grabbing Mr. Cat, and Mr. Cat does an Aside Glance to the audience.
  • Vague Age: Every character aside from Stumpy, who is 10. All we know for sure is that Kaeloo and Mr. Cat are older than Stumpy, Quack-Quack is younger than Kaeloo, and all of Stumpy's sisters are younger than him, with Cramoisie in particular being stated to be "less than 6".
  • Valentine's Day Episode: Episode 83, where the characters have a Valentine's Day party and Mr. Cat tricks Quack Quack into breaking up with Eugly as part of an elaborate scheme to get Kaeloo to kiss him.
  • Vampire Vannabe: Episode 110 revolves around Stumpy wanting to become a vampire. When Quack Quack ends up becoming a vampire, he follows him around being his slave and begging him to bite him so he could also become a vampire. He succeeds in the end, but he steps into the sun seconds later and is reduced to a pile of ash.
  • Vanity License Plate: Any car the main four have will have the letters PTM on its license plate. PTM stands for "Pays Trop Mignon", the name of the place the characters live in the French dub.
  • Versus Character Splash: One appears in Episode 54 depicting Bad Kaeloo and Quack Quack as they are about to fight each other.
  • Villainous Crush: The main antagonist of the show, Mr. Cat, has a massive crush on the protagonist, Kaeloo.
  • Villain with Good Publicity:
    • Despite being an unrepentant jerkass and a liar, Mr. Cat is widely adored by the populace of Smileyland, and it certainly doesn't help that they're not particularly bright. The residents of Smileyland hang onto every word he says and consider him an authority on everything, which has led to countless deaths, injuries, and other misfortunes (all of which are Played for Laughs). The trope is particularly noticeable in seasons 4 and 5, where we see characters other than the usual main and recurring cast and they all listen to everything he says.
    • In seasons 2-4, Pretty, the local Alpha Bitch, was a popular social media influencer with several fans.
  • Visible Odor: In "Let's Play Ecologists", Kaeloo gives Stumpy a piece of stinky cheese to throw away that has squiggly lines over it to represent its odor.
  • Vocal Dissonance: Mr. Cat is only a preteen, but he sounds like a grown adult.
  • Volleying Insults: In Episode 85, Kaeloo and Mr. Cat are in a debate, and Mr. Cat constantly insults Kaeloo instead of countering her points. Kaeloo finally decides she's had enough and starts insulting him back. The fight keeps escalating, and eventually both of them start speaking Angrish. Stumpy finally steps in and breaks up the fight.
  • Vomit Chain Reaction: When Quack Quack throws up in one episode, Kaeloo sees him and she starts vomiting as well.
  • Vomit Discretion Shot: Any time somebody vomits, it'll be just offscreen.
  • Voodoo Doll: In the episode "Let's Play Figurines", the main four get figurines of themselves. Stumpy makes a Deal with the Devil to turn them into voodoo dolls so he can inflict pain on anyone who doesn't obey him.
  • "Wanted!" Poster: In Episode 88, Stumpy, Quack Quack and Mr. Cat, who are dangerous bandits in this episode, see "WANTED" posters of themselves with rewards: 5000 dollars for Mr. Cat, 6500 dollars for Quack Quack, and... 33 cents for Stumpy.
  • Was Too Hard on Him: Nearly every time Kaeloo beats someone up, no matter how much they deserved it, she still feels guilty about hurting them. However, Mr. Cat, the most frequent victim of her wrath, often assures her that it was his own fault that she beat him up.
  • Watch Out for That Tree!: The show turned this trope into a Running Gag where someone usually Stumpy, is driving a car and crashes it into a tree.
  • Wax On, Wax Off: In "Let's Play Tennis", Mr. Cat tells Kaeloo and Stumpy to do random things like tango dancing which have nothing to do with tennis in order to make them better tennis players. The trope is subverted as they aren't actually able to do anything at the actual game, obviously.
  • Wearing It All Wrong: A running gag in the show is for Stumpy to wear underpants on his head.
  • Wedding Smashers: In Episode 60, the bride, the groom and the guests get into a huge fight and ruin the wedding. Kaeloo, oblivious to the whole fiasco, just marries them off anyway.
  • We Have Ways of Making You Talk: Used in an episode where Mr. Cat is dressed as a Nazi:
    Mr. Cat: Me und mein bazooka have ways of making you talk!
  • Weight Woe: In the Beach Episode, Kaeloo decides to play volleyball because she realizes that she's getting fat; however, the plot becomes so sidetracked by the end of the episode that the audience never finds out if she ever did lose the extra weight.
  • Weird Currency:
    • Parodied in one episode where Mr. Cat is a waiter at a restaurant and Stumpy and Quack Quack eat there. When Stumpy hands him some money, Mr. Cat says that the restaurant only accepts ducks as payment, and he cuts Quack Quack in half and takes one half.
    • In another episode, due to a pun being used, Mr. Cat pays for something using live sheep as currency, and the store somehow accepts this.
  • Weirdness Censor: Lavanade has supernatural powers, and ghosts are naturally attracted to her. This means that wherever she goes, a horde of ghosts pops up behind her. The ghosts are visible to Kaeloo, Stumpy, Quack-Quack, Mr. Cat, all of Lavanade's sisters, and Lavanade's teacher, but Lavanade's mother is unable to see them and insists that it's all in Stumpy's head whenever he tries to point it out to her.
  • We Need a Distraction: In one episode where Kaeloo, Stumpy and Mr. Cat are surrounded by Olaf's Mecha-Mooks, Stumpy mentions how in movies people create distractions to escape from situations like this. Mr. Cat uses a golf club to send Stumpy flying into the distance, and all the Mecha-Mooks follow him away.
  • We Want Our Jerk Back!: Pretty gives Mr. Cat a Love Potion disguised as a soda can to make him fall in love with her, but it backfires because he falls in love with the soda can the potion came inand he spends all his time with his soda can instead of being a jerk to the people around him and pissing Kaeloo off. Kaeloo is fairly distraught about Mr. Cat not trying to bully anyone because her entire sense of purpose relied on stopping him from bullying, and also because his attention isn't focused on annoying her and she loves being the focus of his attention.
  • We Will Meet Again: Olaf frequently says this to whoever foils his plans to Take Over the World.
  • Wham Episode:
    • The second season finale proved that Olaf is a Not-So-Harmless Villain. He actually manages to kidnap Quack Quack and freeze Kaeloo and Mr. Cat alive.
    • Episode 105, the Season 3 premiere, ends with Stumpy taking over the animation studio and deciding to write all the episodes himself.
    • Episode 138 focuses on Stumpy's mental handicap. The audience finds out that to some extent, he's faking it.
  • Wham Line:
    • In the episode "Let's Play Hide 'n Hunt", where Mr. Cat teaches Kaeloo and Stumpy to play Hide 'n Hunt, a variant of Hide and Seek, he explains that they hide, he counts to 100, and then...
    Mr. Cat: And at 100... (pulls out bazooka) I shoot everything that moves.
    • In Episode 116, Stumpy is in the hospital and a girl comes to visit him. The others inquire who she is, and get a shocking response:
    Girl: Nice to meet you. I'm Ursula.
  • What Happened to the Mouse?: In "What if We Played at Riding Ponies?", Mr. Cat cons Olaf out of 6000 dollars. While he is eventually punished for it, we never find out if he ever returned the money.
  • What Measure Is a Non-Cute?: Kaeloo's main Berserk Button is people stepping on flowers, even by accident, but she herself has no problems with jumping on and presumably killing a flower that isn't cute.
  • What Measure Is a Non-Super?: In "What if We Played at Riding Ponies?", Pretty and Kaeloo get into a fight over a horse. Suddenly, a unicorn appears out of nowhere, and Kaeloo forgets about the horse and takes the unicorn. Pretty angrily screams and cries until another unicorn shows up, prompting her to shoot the "normal" horse with a gun.
  • What the Hell, Hero?:
    • In "Let's Play Danger Island Survivor", Kaeloo forces her friends to participate on a really lame game show called "Danger Island Survivor". Everyone complains about this, and in the end, Mr. Cat snaps and ends up getting mad at Kaeloo, pointing out how stupid it is. Kaeloo gets really mad and beats him up just for expressing his opinion (which was in fact everyone else's opinion but hers). Stumpy and Quack Quack are both disgusted by her actions, and they and Mr. Cat kick her out of Smileyland (the Reset Button ensures that she's allowed back in by the next episode).
    • In Episode 213, Kaeloo finds out that Mr. Cat has been seeing a therapist, and mistakenly believes that he has pulled a Heel–Face Turn. Mr. Cat (who is actually stuck in a Heel–Face Revolving Door) would much rather keep this information to himself, but Kaeloo decides to go around telling people. She gets called out on this by literally everyone including her own Split Personality.
  • When He Smiles: Mr. Cat's default expression is a grumpy frown and when he is smiling, it's either a creepy Slasher Smile or an arrogant and smug smile. That said, when he makes a genuine smile near the end of episode 105, it's absolutely adorable. Also, his smile in Episode 129, when he wakes up to find Kaeloo snuggling with him is a genuine smile that shows that he's touched.
  • Which Me?: In Episode 232, Stumpy travels through different dimensions with a portal gun and meets several versions of himself, all of whom refer to each other as "me". At one point, one of them asks to borrow the portal gun and Stumpy says no because "only I can use it", but the other him reminds him that "I am you" so technically he's allowed to use it.
  • Who Even Needs a Brain?:

    • Each time Kaeloo or Mr. Cat asks the question, the answer turns out to be Stumpy.
    • One episode had Mr. Cat, Stumpy and Quack Quack scamming people by selling them "lucky underwear". When Kaeloo sees a commercial for it on TV, she laughs and asks who would be dumb enough to fall for that. She then looks around and sees that literally everyone except her is wearing a pair of "lucky underwear".
  • Who Would Want to Watch Us?: At the end of "Let's Play Once Upon A Time" when Stumpy suggests a show about a frog who transforms when angered, Mr. Cat does not seem to like the idea.
  • Who Writes This Crap?!:
    Mr. Cat (yelling): I don't like this episode!
    • The entire plot of Episode 91 revolves around Kaeloo, Stumpy, Quack Quack and Mr. Cat deciding to re-dub older episodes of the show because they think they were poorly written.
    • In the season 4 finale, the characters show the audience how an episode of Kaeloo is typically made. When they get to the part about voice actors recording lines, Mr. Cat wonders out loud what "stupid things" the writers are going to make him say this time.
  • Why Didn't I Think of That?: In Episode 210, Mr. Cat starts his own game show where the objective of the game is to earn good karma by doing good things.
