Western Animation / Fanboy and Chum Chum

Go To

"They dress as superheroes, wearing their underwear on the outside for that Superman look. (They have no out-of-costume alter egos.) Their collective mental landscape is littered with the detritus of sci-fi and fantasy, with the stuff of comics and movies, toys and TV shows. But we don't see the world as they imagine it, Walter Mitty-style; we just see them in their world, imagining...and that world is strange enough."
— A Los Angeles Times reviewer

It all started with a simple idea: two kids wearing superhero costumes and hanging out at a convenience store. A few years later, out of the ashes of Frederator and Nickelodeon's Random! Cartoons comes the squash-and-stretchy CGI world of Fanboy & Chum Chum. The show is about two best friends who live in a water-tower atop of an apartment building with no parental supervision and the strange adventures they have in the town of Galaxy Hills. From turning into vampires, swapping brains with a robot, and taking advantage of slush-machine monster to get through a heat wave, these guys do it all.

Along for the ride are Yo (a Japanese girl with an obsession for digital pets), Kyle (a snarky wizard expelled from his old school, though no one but the titular duo believes him), the Oz (a comic book nerd who lives with his mother), Boog (a bully who works at the local convenience store, but is more interested in playing its arcade game), and Lenny (a sarcastic convenience store employee who hates his job).


The show premiered on November 6, 2009 and it ended after two seasons on November 2, 2012.note  The show's production blog can be found here.

Has a Character Sheet in need of some work.

Contains examples of:

    open/close all folders 

  • Abduction Is Love: Seems to be Yo's belief.
  • Absent Animal Companion: The episode "Rattleskunkupine!" ends with the boys keeping the titular animal and naming it "Scooter". However, it was never seen again since that episode.
  • Absentee Actor: Fanboy and Chum Chum are the only characters to appear in every episode; Yo, Kyle, Lenny, Boog, Oz and Mr. Mufflin have been absent at least once, and there are some episodes where they do appear, but don't have lines.
  • Abnormal Limb Rotation Range: Chum Chum when he came down with the "Frosty Freezy Freeze Fever" in "Berry Sick".
  • Accent Adaptation: Not an accent per se, but in the Polish dub, Kyle speaks with a lisp and relies even more on Sesquipedalian Loquaciousness to compensate for the lack of distinguishable accents in the Polish language, and therefore one that could serve as an equivalent to British.
  • All-CGI Cartoon: The show is animated entirely with computer-generated graphics.
  • All-Cheering All the Time: "2-4-6-8! I think I might regurgitate!"
  • Alliterative Title: Some of the episode titles:
    • "Dollar Day"
    • "Precious Pig"
    • "Chimp Chomp Chumps"
    • "Secret Shopper"
    • "The Tell-Tale Toy".
  • Almighty Janitor: Poopatine.
  • Alpha Bitch: Francine is clearly meant to be this, but she hasn't really done anything outside of looking stuck-up.
  • Always Someone Better: In "The Big Bopper", a new employee at the Frosty Mart proves to be even more of a bully than Boog.
  • And Then John Was a Zombie: Parodied in "Monster in the Mist".
  • Applied Phlebotinum
  • April Fools' Day: Prank Day seems to be the show's equivalent of this.
  • Amusing Injuries
  • Animate Inanimate Object: Professor Flan is a giant walking flan who used to be a normal teacher until Kyle cast a spell on him.
  • Anvil on Head: When Scampers returns from the Digital Pet Cemetery, Fanboy and Chum Chum happily drop a safe on him. Similarly, at the end of "The Frosty Bus", Boog is squashed flat when the Frosty Bus sign falls on him.
  • Arson, Murder, and Jaywalking: One of the recalled toys in "Total Recall" was a complete recreation of a battleship with functioning weaponry. It was recalled because the plastic flag was a choking hazard.
  • Art Evolution: The Pilot Episode "Fanboy" from Random! Cartoons looks much different than the series now. The CGI animation was more like of The Adventures of Jimmy Neutron, Boy Genius, in that it was darker, stiffer, and less refined. Fanboy's costume was white and purple, Chum Chum was bigger and taller, Barry the Ice Monster was large and fierce, and Lenny was a white guy with an orange afro. Now the animation is much more lucid, colorful, character designs and voices have changed, and it's more along the lines of what The Ren & Stimpy Show would look like in CGI.
  • Artistic License – Education:
    • "Excuse Me": Fanboy, Chum Chum and Kyle get away with missing class constantly due to all kinds of unrealistic fake excuse notes. Mr Mufflin falls for all of them until it is discovered outright that they are lying. He even accepts an excuse note to excuse FanKyleChum (actually a real student) from class forever. Even given Rule of Funny, no teacher would accept any of these.
    • "Marsha, Marsha, Marsha": Fanboy and Chum Chum accidentally end up in a kindergarten where they are forced to stay all day because the teacher doesn't believe that they're not kindergarten students. While there, they discover that their former classmate Marsha was sent here after Fanboy got snot all over her standardized test. No teacher would use something like this as a reason to fail a student to the point of sending them back five grades. Additionally, Marsha would just be made to retake the test at a later date, especially since it wasn't her fault the test got ruined.
    • According to Word of God, Chum Chum is two years younger than Fanboy, but is in the same class due to Fanboy sneaking him in and no one noticing. Seemingly, Adults Are Useless and bureaucracy barely exists in this world.
  • Aside Glance: Kyle does this in "Prank Master" after Fanboy asks him to pull his finger.
  • Ate the Spoon: The Lunch Lady's glop corrodes a fork in "Little Glop of Horrors."
  • Audience Surrogate: Kyle can be seen as one, given that he seems to be the one rational and sane character in a world of wild and crazy cloudcuckoolanders.
  • Ax-Crazy: Marsha. She spends her entire episode trying to kill Fanboy.
  • Bad Humor Truck: It's nearly impossible for Fanboy and Chum Chum to get a Frosty Freezy Freeze from the Frosty Bus when Boog is behind the wheel.
  • Bad Job, Worse Uniform: Boog and Lenny's work shirts aren't that bad, but they have to wear Frosty Freezy Freeze cup hats.
  • Bag of Holding: Fanboy has a desk of holding at school, and he and Chum Chum go excavating inside it in order to find his missing textbook in "Schoolhouse Lock".
  • Baleful Polymorph: Subverted with Fanboy and Boog becoming puppets in "Strings Attached" and loving it so much that they fight with each other about who gets to do a good deed to permanently stay that way. Later in the episode, Boog is turned into a frog.
  • Berserk Button: Fannahilator goes berserks if Super Chum calls anyone besides him his "Best Nemesis Forever".
  • Be the Ball: In "Chimp Chomp Chumps", Boog squishes Chum Chum into a ball and whacks him with a mallet like a golf ball.

  • Big Brother Instinct: Fanboy has a protective side for Chum Chum as seen in "Brain Drain" and "Saving Private Chum Chum".
  • Big "NO!": Fanboy says it as Chum Chum spends their only dollar on the Chimp Chomp machine in "Dollar Day", Boog does this in "Fanboy in the Plastic Bubble" after his stack of money explodes, and Lenny has a Slow Motion one in "The Great Bicycle Mystery" when he sees that Bikey has been destroyed.
    • Chum Chum screams one in "Brain Drain" as Fanboy tries to eat his own brain.
    • In "There Will Be Shrieks", both Fanboy and Chum Chum scream this in unison after Mr. Trick steals their taste, impacted with Eat the Camera.
    • In "Speed Eraser", Kyle screams this twice: first after his body is erased and Fanboy unknowingly tries to erase his head, and again when he erases his wand, complete with an Overly Long Scream.
  • Big Word Shout: Fanboy lets out one in "Stan-Arctica" after thinking Man-Arctica has died, complete with a Skyward Scream:
    Fanboy: How can you do this to me, Man-Arctica?!? HOOOOOOOOOOOOOOOO... [coughs] ...OOOOOOOOOOOOOW?!?
  • Big "YES!": This is Poopatine's repeated response to Fanboy and Chum Chum's gums being allowed in school.
  • Black Dot Pupils: A rare usage of this in CGI animation. The only exception is Poopatine whose are gold, while Man-Arctica's are blank white sockets.
  • Bottle Episode: There are a few episodes that remain in only one location the whole episode; there are also a few that remain indoors, and one that's completely outdoors.
  • Brain Freeze: The Title Sequence includes this.
  • Bread, Eggs, Breaded Eggs: In "Fanboy Ahoy", three of the things the boys put in their treasure chest are candy, money, and candy money.
  • Bread, Eggs, Milk, Squick: In "Chicken Pox", Kyle tells the titular duo that all he has to do to get better is bed rest, plenty of fluids, and lay an egg.
  • Brick Joke:
    • The "charm to summon a griffon spell" in "Wizboy". Fanboy reads it out loud, which sends Kyle into a panic, but nothing happens. Later on, the griffon actually does show up and takes Kyle away, which notably also apparently saves the boys' lives.
    • At the beginning of "Dollar Day", Fanboy abuptly stops while walking which causes his brain to fall out. Later in the episode when he and Chum Chum are trying to come up with a way to get a dollar, he shouts "We've got to THINK!". Chum Chum then leaves the screen for a second and comes back with Fanboy's brain and puts it back in his head.
    • Oz's plan to make a candy ark in "There Will Be Shrieks", which is described the beginning of the episode but doesn't reappear until the very end.
  • Bring My Brown Pants: When Scampers is emerging from the television at the end of "Digital Pet Cemetery", Fanboy, Chum Chum, and Yo yell for Oz to do something. He replies with, "Can't talk... soiling self!"
    • In "Monster in the Mist", Fanboy, Chum Chum, and Boog spray Lenny with cheese when they think he's the monster.
    Lenny: What's wrong with you people?!
    Boog: There's a monster on the loose!
    Fanboy: Just like in ''Monster in the Mist''!
    Chum Chum: The miiiiiiissst...
    Lenny: That's ridiculous.
    Chum Chum: (points to Boog) He saw it! It's huge!
    Boog: Yeah, huge! I've never been so scared! Uh... speaking of, I... I gotta hit the bathroom and rinse out a few things, alright?
    • In "A Bopwork Orange", Fanboy and Chum Chum decide to try another method to cure Boog's bopping besides Electric Torture. Boog responds to this with, "If it doesn't shock me, I'm all for it! I'm down to my last clean underwear anyway."
  • Bowel-Breaking Bricks: When everyone fails the test in "I, Fanbot" and corners the robotic Fanboy, Chum Chum points out, "Uh, Fanbot, I think you oiled yourself."

  • Burping Contest: "The Frosty Bus" episode begins with the title characters doing this.
  • Butt-Monkey: Nearly all the characters have been this at some point or another.
  • Calvinball: Kyle comes over to the Fanlair in "Cold War", he tries to play board games and action figures with Fanboy and Chum Chum, but they have such random rules that Kyle quits out of frustration.
    • And when he calls shenanigans, it turns out to be the name of their most random game, considering it involves an army of Fanboy and Chum Chum clones.
  • Camera Abuse: In "Fanboy in the Plastic Bubble", the bubble bounces on the camera lens.
    • Again in "Lucky Chumps" when Lucky Charlie whips the boys at the camera.
  • Can Only Move the Eyes: Both Fanboy and Chum Chum when they are frozen in "Berry Sick" and "Freeze Tag".
    • At the end of "Fan-Bidextrous, Fanboy somehow only has the ability to move his eyes and talk after getting stuck to a cement-coated Mr. Mufflin.
  • Camp Gay: "It's time to get fabulous with Crabulus!"
  • Captain Morgan Pose: Fanboy has one in the episode title card for "Fanboy A'hoy!".
  • Captain Obvious:
    • Chum Chum is shown to be obviously smarter than Fanboy, as seen in "Fangboy" when he easily recognizes his "vampire bite" as just a mosquito bite, and in "The Incredible Shrinking Fanboy" the result of Fanboy thinking he's shrinking is because the measuring flower grew overnight.
    • In "Heroes vs. Villains", this is the name of the superhero persona Joey assumes in the imagination sequence.
  • Cash Cow Franchise: Man-Arctica seems to be an in-universe example. So far comic books, action figures, music CDs, cereal and rides dedicated to him have been shown.
  • Chainsaw Good: In "Crib Notes", Fanboy and Chum Chum juggle chainsaws as an attempt to help baby Kyle go to sleep. It doesn't go well.
  • Chair Reveal: Oz has a comedic one in "Freeze Tag" when Fanboy and Chum Chum try to hide from Man-arctica in his store. As he talks about his anticipation for Man-arctica's appearance, Oz swivels the chair to reveal himself holding a bucket of chicken with a face smeared with barbecue sauce.
  • Chekhov's Gunman: At the start of "Dollar Day'', Fanboy talks about building a robot someday. The same robot arrives from the future at the end of the episode.
  • Chromatic Arrangement: Kyle (red), Chum Chum (yellow/orange), and Fanboy (green).
  • Clark Kenting: Man-Arctica does this in "Stan Arctica" by wearing glasses and taking a job at Oz's comic shop. No one recognizes him, despite having super strength and icicles tearing out of his clothes.
    • Fanboy, in "Fanboyfriend" pulls out a pair of coke-bottle-glasses, creating a "secret identity" to hide from Lupe. It doesn't work.
  • Cloud Cuckoolander: Both the main characters are this, but considering how crazy their world is...
  • Companion Cube: Fanboy went to the school dance with a sentient mop for a date.
    • Boog talks to the Chimp Chomp machine as if it was his girlfriend. He acts the same way with his car named Sandy.
    • Lenny acts similarly with his bike, Bikey, but to a lesser extent.
    • Yo's best friend is a pine cone named Ingrid.
    • Janitor Poopatine seems to have a personal relationship with his mechanized chair, Brenda.
  • Company Cross References: In one episode, Chum Chum's pirate name is "Chumbucket", which is the name of Plankton's restaurant in SpongeBob SquarePants.
  • Continuity Nod: While waiting in line for the roller coaster in "Man-Arctica the Ride", Fanboy taunts Kyle by saying he's getting chicken pox, which is a reference to a past episode.
    • In "The Incredible Chulk", Fanboy's Glass Eye from "Fan vs. Wild" falls out after he's thrown on the camera by Boog.
    • "HypnotOzed" makes several references to "The Hard Sell" when Oz's mom says that if Oz doesn't make any sales, she'll turn his store into a yogurt shop, then Fanboy and Chum Chum show Oz the first dollar he made, and Fedora Man returns to take the dollar back.
    • In "Wizboy", Kyle casually references how he got expelled from his Wizarding School by turning his teacher into a flan. This teacher appears in the season two episode "Crib Notes" to administer Kyle's test to be readmitted to his school. In "Kids in the Hall", Professor Flan returns when Kyle tries to get accepted into Milkweed Academy again.
  • Contrived Coincidence: In "Monster in the Mist" Boog and Lenny both see Fanboy and Chum Chum as the same monster despite having their vision impaired in different ways, and the exact same monster turns out to be Real After All.
  • Cool Toy: Mechatech. Fanboy wanted one so badly that he traded Chum Chum to Yo in return for hers.
  • Costume Copycat: In "Lord of the Rings", Kyle disguises himself as Chum Chum in order to learn Fanboy's ring trick. He looks exactly like Chum Chum, except with protruding braces and British accent, which manages to fool Fanboy and the real Chum Chum anyway.
  • Covered in Gunge: Oh, man, where to start with this show? Fanboy has been sneezed on, doused with Frosty Freezy Freeze slush, and assaulted with eggs, just to name a few times.
    • In one episode, his superhero costume got so incredibly dirty that it actually came to life.
  • Cranium Compartment: Fanboy can open the top of his head like a jar at will whenever he wants. This becomes important in "Brain Drain" as it's used to lose his brain.
  • Cue the Flying Pigs: When Yo asks the duo to take care of Scampers in "Digital Pet Cemetery", Chum Chum is seen releasing a pig with wings.
    "And they said you'd never fly!"
  • Cup Holders: Boog's car has a pretty fancy one with a mechanized claw that grabs the cup and locks it in the dash.
  • Cute and Psycho: Marsha. She was the class's star pupil until Fanboy sneezed on her test. Then things got ugly...
  • Cuteness Proximity: In "Battle of the Stands", Yo and Lupe's entire method of gaining customers at their lemonade stand is to use their girlish charm. When Fanboy retaliates by disguising himself as a baby, the customers immediately abandon the stand in favor of adoring him instead.
  • Darker and Edgier: "Fangboy", "Book Report of the Dead", "There Will Be Shrieks" and "Speed Eraser"; it's justified since the third (and maaaybe the second example) was a halloween special.
  • Deadpan Snarker: Kyle.
  • Dead Pet Sketch: The episode "Digital Pet Cemetery", where Fanboy and Chum Chum take care of Yo's digital pet, Scampers, only to have it "power down" and return as a zombie.
  • Department of Redundancy Department: Frosty Freezy Freeze.
  • Description Cut: In "Saving Private Chum Chum", Fanboy worries about Chum Chum suffering while trapped in Mr. Mufflin's desk. The camera then cuts to Chum Chum laughing and playing with toys.
  • Deranged Animation
  • Deus ex Machina: "Fan Vs. Wild" is resolved when it is revealed that Fanboy has a Glass Eye that can shoot lasers.
  • Diagonal Cut: Happens twice - in "Digital Pet Cemetery", when Scampers comes back and cuts Fanboy's head to pieces with his claws; and in "Norse-ing Around", when Thorvald commands Lenny to bring him drinks. An irritated Lenny then says "I'm not your servant!", to which Thorvald responds by cutting his cup hat into half.
  • Disembodied Eyebrows: A rare CGI example to be exact, due to the deranged 90s architecture of the show.
  • Disgusting Public Toilet: The school's oldest bathroom has these.
  • Disney Acid Sequence: Fanboy and Chum Chum have a rather surreal musical number about living at the Frosty Mart in "Jingle Fever".
    • The candy song in "There Will Be Shrieks".
    • Also the Training Montage in "Eyes on the Prize".
  • Does This Remind You of Anything?:
    • In "A Bopwork Orange", Boog's impulsive bopping is played out like a drug addiction, and at the end of the episode, Agent Johnson even says, "Just say no to bops." In the episode's storyboard, Boog refuses to be separated from the Chimp Chomp machine because "She's even got my initials tatooed above her coin slot!". It's even funnier when you realize his initials are "B.S."
    • In "Fan-bidextrous", Chum Chum introduces Fanboy to his own arm.
    Fanboy: Firm handshake, I like this guy.
    Chum Chum: I've been trying to get you two together for a while.
    • The way Fanboy and Chum Chum lick the dirt off of Cuppy in "Refill Madness" is strangely reminiscent of a certain video on the Internet...
    • The Global Warmer's outfit.
    • In "Speed Eraser", Fanboy accidentally erases Kyle's body and has a few trouble getting his wands, before erasing them as well - he is obviously doing it on purpose, as viewers can see this as a punishment for Kyle.
    • Fanboy giving Chum Chum his nose back in "Pick a Nose" is played like proposing marriage, as Fanboy kneels in front of Chum Chum while presenting his nose in a container resembling a wedding ring box and Chum Chum responds by stating that Fanboy has made him the happiest boy.
  • A Dog Ate My Homework: A variant is used in "Chicken Pox".
    Chum Chum: Hey, Kyle, we brought you your homework, but a dog ate it.
    Fanboy: All the times we said it happened to us... and it happens to you! I mean, what are the odds?
    • In "Kids in the Hall", Kyle frantically tries to turn in an essay to Professor Flan, but along the way, a three-headed dog from another dimension eats the paper.
  • Downer Ending: In "Chimp Chomp Chumps", Fanboy, Chum Chum, and Boog don't get to see the Chimp Chomp movie on time and have to wait another year to see the sequel while in line.
  • Dramatic Irony: In "Slime Day", the audience knows the phrase to get slimed is simply "I don't know", but Fanboy and Chum Chum think everyone actually doesn't know it. Even when a blob of slime spells out the phrase, they think the slime doesn't know as well.
  • The Dreaded Toilet Duty: In "The Janitor's Apprentice", Janitor Poopatine tries to punish Fanboy and Chum Chum for making a mess at the cafeteria by making them clean the school. He takes them to a filthy bathroom and Fanboy is terrified that they might have to clean the toilets. Poopatine wants them to refill the soap dispensers... which someone threw into the toilets.
  • Dropped After the Pilot: The original Random! Cartoons pilot short established that Fanboy and Chum Chum idolize a superhero named Fan Man, who doesn't appear at all in the actual series, taking with him the explanation for Fanboy's codename.

  • Early Installment Character-Design Difference:
    • The Random! Cartoons pilot had the green parts of Fanboy's costume colored gray and depicted Chum Chum having string ties similar to those on Robin's tunic rather than an insignia bearing the silhouette of his face.
    • Lenny was depicted in the pilot as a blond Caucasian when the actual series depicts him as an African-American.
  • Early Installment Weirdness:
    • In the first episode, the titular duo thought Kyle was only pretending to be a wizard even though he really is one, but in later episodes, they seem to know the truth.
    • The same first episode has Fanboy use an "Ice Monster Bun Bun" (the same treat from the pilot short), but since then it was never mentioned, with Frosty Freezy Freeze taking its place. It can be seen as an ad in the Frosty Mart, however.
  • Ego Polis: In "Norse-ing Around", Thorvald claims that the capital of Sweden is Thorvaldia, and throws a fit when Mr. Mufflin claims it isn't, saying he conquered and renamed it himself.
  • Enfant Terrible: The toddlers in "The Great Bicycle Mystery".
  • Enemy Mine: In "Prank Master", Fanboy and Chum Chum work together with Boog, who antagonizes them in every other episode.
  • Episode Title Card: See them all here.
  • Ethereal Choir/Ominous Latin Chanting: This sometimes accompanies scenes where Kyle begins to cast a powerful spell or is being antagonistic.
  • Everybody Cries: In the episode "A Very Brrr-y Icemas", when Fanboy accidentally removes Mr. Mufflin from his Man-Arctica costume, the incident causes the witnessing crowd in the Frosty Mart to burst out crying.
  • "Everybody Laughs" Ending: "Digital Pet Cemetery" has this, with Chum Chum delivering the last line of, "Real funny, guys, now get me out of here!"
  • Everyone Is a Suspect: In "The Great Bicycle Mystery".
  • Everythings Betterwith Rainbows: In the episode "Lucky Chums" Fanboy and Chum Chum squeeze one out of the leprechaun cereal mascot Lucky Charlie. A myriad of "Double Rainbow" references predictably ensue.
  • Everything's Deader with Zombies: Scampers in "Digital Pet Cemetery" and Mr. Mufflin in "The Book Report of the Dead".
  • Evil Twin: Evil Cousin: Brizwald, who tries to steal Oz's rare comic book in "Risky Brizness" by using his shadow.
  • Expy: Fanboy resembles Sheen from Jimmy Neutron in appearance and behavior. His head also resembles Ed's from Tonic Trouble.

  • Eye Pop
  • Face Palm:

    • Janitor Poopatine has one in "The Janitor's Apprentice", after he sees Fanboy and Chum Chum cleaning out ketchup with peanut butter.
  • The Face of the Sun: Used in the montage in "Totall Recall", accompanied by a pink glade of flowers and a rainbow.
  • Fat Idiot: Mr. Mufflin
  • "Fawlty Towers" Plot: In "Sigmund the Sorcerer", Kyle lies to Sigmund about being a skilled, high-achieving wizard and tells him that Fanboy and Chum Chum are his elf servants. The facade continues until Sigmund proposes to buy his "servants" and send him back to Milkweed Academy, forcing Kyle to reveal the truth.
  • Fictional Video Game / Defictionalization: Chimp Chomp. Now a flash game.
  • Flat-Earth Atheist: No one will believe Kyle is a real wizard no matter what he does to try to prove them wrong.

  • Free-Range Children: Rarely do we even hear of any of the kids' parents.

  • French Maid: Boog wears a French maid outfit, complete with the choker, in one scene of "Chimp Chomp Chumps".
  • Fun-Hating Confiscating Adult:
    • Their teacher confiscated Kyle's magic wand and told him he could have it back at the end of the year. Justified example, because Kyle was about to use it to cast a hostile spell on the titular duo.
    • He does it again in "Saving Private Chum Chum", when he sees everyone playing with toys and takes them all away, even Chum Chum due to swallowing a ball.
  • G-Rated Drug: Frosty Freezy Freeze can be easily considered such.
  • Gag Nose: The whole plot of "Pick a Nose", with removable noses and all.
  • Genre Throwback: This show looks and feels a lot like a 90s cartoon, but is done with 3D animation instead of 2D.
  • Get a Hold of Yourself, Man!: When Fanboy and Chum Chum hear that Agent 08 has been recalled:
    Chum Chum: What do we do, what do we do, what do we do?
    Fanboy: (slaps Chum Chum) Calm down, get a hold of yourself.
    • Also used in "Digital Pet Cemetery", but with reversed roles.
  • Gigantic Gulp: Cupzilla. "45 gallons of bladder-bustin' refreshment!"
  • Girls Have Cooties: It's the reason why Fanboy turns down Yo's offer to have a sip of the Frosty Freezy Freeze despite being stranded on the Frosty Mart roof in "Fan VS Wild".
  • Glass Eye: Fanboy has one in "Fan VS Wild" that serves as a Deus ex Machina.
  • Gonk:
    • Lupe. None of the characters are anywhere near to being pretty, but just look at her. Geeze.
    • Mr. Mufflin might be the worst out of them all, for example...
  • Go Back to the Source: In "Brain Freeze", FB and CC end up having a Frosty Freezy Freeze-infused hangover night which results in them losing their trademark underwear outside their suits. They manage to find the underwear in the Frosty Freezy Freeze machine, the same place they learned the Berry Pink flavor was replaced with Radioactive Red early in the episode.
  • Gratuitous Spanish: Lupe sometimes uses Spanish words in her sentences.
  • Gross-Out Show: Boy, is it ever.
  • Hard-Work Montage: "Fan VS Wild" has one when Fanboy, Chum Chum, and Kyle build Oz's blueprint to rescue them, but it turns out to be a display case for Oz's shop.
  • Harmless Freezing: The Secret Shopper and Lenny are both frozen in "Secret Shopper", but they are perfectly fine after they defrost.
    • Averted in '"Refill Madness":
    Lenny: I'm getting Frosty Bitey Bite!
    • Also averted in "Freeze Tag", where everyone in town runs away from Man-Arctica in terror as he tries to turn them all into icicles.
  • Harmless Voltage: Boog was forced to wear a collar that shocked him every time he thought about bopping, but its painful effects didn't seem to last longer than a few seconds.
    • Also, Agent 08 was recalled due to its tendency to explode and shock people, but no matter how many times it electrocuted Fanboy and Chum Chum, the two were always back to normal in the next scene.
  • Helium Speech: Happens to Fanboy, Chum Chum, and Boog at the end of "Fanboy in the Plastic Bubble."

  • Halloween Episode: "There Will Be Shrieks".
  • Hoist by His Own Petard:
    • Sometimes Kyle's spells tend to turn on himself.
      • On example is the spell "Charm to summon a griffon" in the pilot. He imagines the victim to be Fanboy, but then Fanboy swipes the spellbook and utters the incantation out loud, next to him. Minutes later, that griffon comes down from the skies, scoops up Kyle himself, and carries him away.
      • The magic eraser Kyle gives Fanboy in "Speed Eraser" has the ability to erase anything from existance; after literally attaching it to Fanboy, he is so upset and shocked he accidentally (yet, purposefully) erases Kyle's own body, and later, his wand.
  • Honesty Aesop: In the episode "The Tell-Tale Toy", Fanboy accidentally opens an Ultra Ninja toy meant for Chum Chum and breaks it, and he tries to hide the evidence from him so he doesn't find out. When he can't take it anymore, he is forced to tell the truth, but in a surprise "Shaggy Dog" Story, it turns out Chum Chum didn't want the ninja at all — he was going to give it to Fanboy and only wanted the box that the toy came in.
  • Horrible Camping Trip: In "Fan VS Wild", Fanboy, Chum Chum, and Kyle go camping on the roof of the Frosty Mart and become stranded as if they're stuck on a mountain.
  • Horny Vikings: Thorvald the Red, brother of Olaf, son of Smellanor, third-high scorer on Whack-A-Dragon.
  • Huge Schoolgirl: Lupe. Marsha could also count.

    Janitor Poopatine: Alright, alright! You can have your gum! And chew it, too.

  • Inexplicably Identical Individuals:
    • All three of the school's lunch ladies look identical except their dresses are different colors.

    • All three cheerleaders look identical.

    • Kyle mentions in "Cold War" he never actually wanted anyone to play with him before, but he himself doesn't want to play with Fanboy and Chum Chum because they make up rules for their games. Justified, as he isn't creative and optimistic like they are.
  • I Taste Delicious: When Barry freezes the titular duo in "Berry Sick" the two don't mind because they taste like Frosty Freezy Freeze.
  • Jaw Drop: When the titular duo is forced to clean the school's oldest bathroom:

    • Chum Chum does this when he sees Moppy for the first time.

  • Karma Houdini: Fanboy and Chum Chum kind of fit this, they usually manage to get away with annoying everyone in sight, the few times that they DO receive punishment they manage to drag someone else into it with them, like Kyle so it's not as bad for them.
  • Keet: Fanboy, and how!

  • Limited Wardrobe: All the characters wear the same clothes, with the titular duo being the guiltiest.
  • Literal-Minded: Fanboy and Chum Chum act like this pretty frequently, but in "Crib Notes", when baby Kyle says he wants to be rocked to sleep, the duo break out electric guitars and perform some rock and roll.
  • Living Shadow: Brizwald has one in "Risky Brizness", and he uses it to steal Oz's comic book. Fanboy and Chum Chum fight him by using shadow puppets.

  • Maintain the Lie: "Sigmund the Sorcerer"
  • May Contain Evil: The Agent 8 box says things like "quick action oil spill" and "octo-shock grip". Of course, Fanboy and Chum Chum think it's awesome.

  • Minimalist Cast: Taken Up to Eleven in "The Tale Tell Toy" - the only characters to appear are the titular duo, the only location being the Fanlair and no place more.
  • The More You Know: Parodied at the end of "The Big Bopper", where Fanboy and Chum Chum conclude that no one learned anything from the episode. The screen then says, "The Less You Know."
  • Morality Pet:
    • Recent episodes feature Lenny being one for Boog, although their friendship remains vitriolic at best.

  • Mystery Meat: The eponymous glop from "Little Glop of Horrors".
  • Nails on a Blackboard: This is how Fanboy gets everyone's attention in "The Great Bicycle Mystery".

  • Name and Name
  • Negative Continuity: The Frosty Mart has been destroyed several times and characters have been maimed in various ways, but none of it carries over to the next episode.
  • Never My Fault: In "Monster in the Mist" Boog and Lenny blame Fanboy and Chum Chum for making them believe they were the monster when it was actually their own impaired eye sight that was to blame.
  • Never Say "Die":
    • Kyle says the phrase "Goodbye forever" when armed with a fireball in the pilot, shocking viewers. Luckily, he himself gets taken out at the last minute.
    • Marsha says Fanboy will "take a permanent nap" when naptime comes.
    • Averted in "Fanboy in the Plastic Bubble": "PREPARE FOR DEATH BY BOP!"
  • Nice, Mean, and In-Between: Chum Chum is the nice one, the Cheerful Child who is sweet, rather innocent, and can have his feelings hurt sometimes. Kyle is the mean one, a wizard who serves as a snarky Grumpy Bear who despises anything fun, but can have his Jerk with a Heart of Gold moments, other times acting as a full-on Villain Protagonist. Fanboy is the inbetween, due to being dimwitted and funny, but can be more serious than Chum Chum. You can tell which is which by their clothing colors.
    • The three main grownups are this, too. Oz is a hoarder but a friend to the two boys, Boog is a bully who bops anyone, and Lenny mediates between the two, because he's always annoyed and flustered but sometimes has a soft side.
    • Some of the girls are also this. Lupe is soft-hearted; Francine is stuck-up; Yo is a wild Geinki Girl who has a warm side at times.
  • Night-Vision Goggles: Used by Boog in "Fanboy in the Plastic Bubble."
  • Ninja Pirate Zombie Robot: In Lights Out, the boys want to watch a film that is literally entitled Robot Pirate Ninja President.

  • No Ending: Used fairly often due to the show's Negative Continuity.
  • Non-Nude Bathing: The two main characters bathe with their superhero costumes on.
  • The Noseless: Fanboy and Chum Chum are capable of detaching their noses from their faces and swapping them with each other in "Pick a Nose", leaving brief moments where neither of them has a nose. In "Fanboy Stinks", Chum Chum removes his nose because he can't stand Fanboy's odor, but he is still able to smell him through his ears.
  • No One Should Survive That:
    • In "Excuse Me", the boys bounce Kyle on their springs so hard they fly right up into space...then drop back down to earth easily. They wouldn't have did so in real life, as space has no gravity. Also, it would take a long time to get to space as they need to break the sound barrier first.
    • At the end of "Lord of the Rings", Kyle falls into a Lava Pit and is immediately rescued by a griffon without a singe.

  • Ocular Gushers: Every time a character cries, the tears stream from their eyes like a sprinkler.
  • Off-Model: In the John Kricfalusi-esque way. If you've ever seen any of the storyboards, you probably know that they look completely different than the actual show. As evidenced by a storyboard artist, this is what is considered to be too far off the mark.
  • Offscreen Crash: At the beginning of "Strings Attached", Fanboy throws a huge water balloon out into the street. Car crashes and alarms are heard.
    Fanboy: Well, it looks like they're all good swimmers, so it's a happy ending after all.
  • Ominous Fog: "Monster in the Mist" is all about this trope.
  • Only Sane Man: Kyle and Lenny often fill this role, the former being one of few characters to have a common sense.
  • Opening Shout-Out:
    • In "Attack of the Clones" when Cloneboy and Chum Clone try the Frosty Freezy Freeze, they launch into the "Brain freeze!" sequence from the theme song.
    • In "The Janitor's Apprentice" when the boys see Janitor Poopatine's Dump Star and "Attack of the Clones" when they witness Boog's bop arms, their reaction is taken from the very end of the theme song: "Ohhhh! That's nice!"
  • Organ Autonomy: After Fanboy refuses to take a bath, his hand grows mushrooms for eyes and gains the personality of a mobster named Stinks. A particularly squicky scene results when Stinks "has to use the little hand's room."
  • Our Gryphons Are Different: Apparently, griffons exist in this universe, usually as creatures summoned by Kyle.
  • Our Vampires Are Different: The "Fangboy" episode.
  • Overly Long Gag:
    • Fanboy screams "Aaaah! What have I done?!" no less than seven times in "The Tell-Tale Toy".
    • Kyle's screaming in "There Will Be Shrieks". Technically, he screams one thousand times in a row, but only the first ten or so are heard.
  • Pac-Man Fever: Justified by the fact that the only video games seen in the series so far are arcade games and a virtual pet.
  • Parental Abandonment:
    • Played straight. Fanboy and Chum Chum's parents are never seen nor mentioned, same with Kyle and other children. Matter of fact, there's no trace of anyone's parents anywhere, with only brief mentions to relatives.
    • Yo and Oz are the only ones who avert this, though the latter is the only one whose are shown, while the former's is only mentioned.
  • Paper-Thin Disguise: In "Battle of the Stands", Fanboy disguises himself as a baby so he and Chum Chum can gather more customers at their lemonade stand than Yo and Lupe. Only Yo and Lupe can see through his disguise, which is nothing more than a bonnet and a pacifier.
    • Chum Chum as the Toxic Teapot in "Fanboyfriend". Lupe doesn't notice.
  • Peek-a-Bangs: Ms. Olive the kindergarten teacher.
  • Phrase Catcher: Chum Chum usually says "Poop!" whenever someone mentions Poopatine's name out loud.
  • Picture Day: Fanboy and Chum Chum have class picture day in "Pick a Nose". "Funny Face" does the same.
  • Pie in the Face: Happens several times in "Prank Master".
  • The Pig-Pen: Fanboy becomes this when he tries to set a world record for the longest time without taking a bath.
  • Pinocchio Nose: Literally happens to Fanboy in "Strings Attached" when he says he'll do a good deed.
  • Pirate: The episode "Fanboy A'hoy" has all the kids as pirates.
  • Please, I Will Do Anything!: The entire point of the "Chimp Chomp Chumps" episode, in which Boog begs Fanboy and Chum Chum for their ticket to the Chimp Chomp movie. Hilarity ensues.
  • Plot-Induced Stupidity: There are times where Chum Chum and/or Fanboy just has to be completely stupid to jump start the plot of an episode...but mostly Chum Chum.
  • Pokémon Speak: Chum Chum's cousin does this.
  • Potty Emergency: Fanboy and Chum Chum experience this when they are trapped inside of a plastic bubble and Boog teases them by pouring a pitcher of water into a cup.
  • Potty Failure: Used as a joke at the end of "The Incredible Shrinking Fanboy" when Yo's dollhouse is stuck on Fanboy's body. He tells Chum Chum to hurry with removing it because "the basement's flooding".
  • The Precious, Precious Car: Sandy. Also Precious Precious Arcade Game.
  • Psycho Electro: Boog at the end of "A Bopwork Orange".
  • Puppet Permutation: Fanboy and Boog in "Strings Attached".
  • Puppy-Dog Eyes: Mr. Mufflin gets these when he reads Fanboy's, Chum Chum's, and Kyle's sappy excuse notes because they were "saving kittens in an avalanche" or something similar.
  • Race Against the Clock:
    • In "The Hard Sell", Oz has to sell something before 6:00 otherwise his mother will shut down his store and turn it into a yogurt shop.
    • In "Strings Attached", Fanboy has to do one good deed by 5:00 if he wishes to keep his transformation into a marionette.
  • Rapid-Fire "No!":
    • Poopatine gives one in "The Sword in the Throne" as the boys enter the sacred bathroom stall to see the Plunger of Power.
    • In "Crib Notes", this was Necronomicon's response when Kyle asks him for the "crib notes" spell.
    • In "Speed Eraser", Kyle gives one as Fanboy (purposefully) tries to erase his own head.
  • "Rashomon"-Style: "The Great Bicycle Mystery" has several characters retelling their version of what happened to Lenny's destroyed bicycle, but details in each story conflict with one another. The true culprits turned out to be FB and CC themselves, as the security camera reveals they accidentally landed on the bike, crushing it, from a failed stunt.
  • Reaching Between the Lines: In "Cold War", Fanboy eats Lenny's nachos while talking with him on the phone.
  • Real After All: The monster in "Monster in the Mist".
  • Reality Warper: The titular boys are all but stated to be this. "Separation Anxiety" even reveals the boys must be together because separating them will rip a hole in the space-time continuum.
  • Real Time: Near the end of “The Hard Sell”, Oz’s mom warns him she’ll be coming downstairs in one minute. Exactly one minute after she says that, she’s in the store after Oz sells the pickle jar.
  • "The Reason You Suck" Speech: Kyle gives one to Fanboy and Chum Chum in "Cold War" upon getting mad at the fact they make up rules for their games; for some reason they are smiling throughout all of it and don't show any sign of their feelings being hurt.
  • Record Needle Scratch: Has happened on more than one occasion.
  • Red Eyes, Take Warning:
    • Kyle has these in "Tooth or Scare" and "Heroes vs. Villains".
    • The new lunch lady at the end of "Norse Code".
  • Red Oni, Blue Oni:
    • Fanboy and Chum Chum are both red to Kyle's blue, and Boog is red to Lenny's blue.
    • In episodes and scenes where it's just the two main characters, depending on the episode, they tend to swap places with Fanboy being responsible (blue) and thinking up some sort of kooky plan (red) while Chum Chum is an excitable Cheerful Child (red) who tends to be the voice of reason when his friend flies off the handle (blue).
  • Repetitive Name: Chum Chum.
  • Reports of My Death Were Greatly Exaggerated: The main point of "Stan-Arctica" is Fanboy — and virtually everyone else in town — believes Man-Arctica died after reading a comic book where he falls down a black hole after being defeated by Global Warmer. When the hero is revealed to have survived, he disguises himself as a mild mannered citizen and takes up a job at Oz's store to keep up the act.
  • Retcon: Two Season 1 episodes reference Christmas - in "Night Morning", Chum Chum says Man-Arctica delivers toys to kids; Yo corrects him by saying "Isn't that Santa Clause?". Later in "Eyes on the Prize", Fanboy says buying a cereal of Man-Arcticrunch is like Christmas but with cereal. Come the Season 2 Christmas Episode "A Very Brrr-y Icemas", Christmas is not celebrated at all - it's parodied as Icemas, with Man-Arctica acting like Santa Clause.
  • Revenge:
    • Marsha used to be the star student, but thanks to Fanboy sneezing on her placement test, she received such a failing grade that she is sent back to kindergarten. She vowed payback on him because of this.
    • Kyle is extremely jealous when Mr. Mufflin gives his position of "board eraser-er" to Fanboy because of his impressive erasing routine; to get back at him, he is presented with a cursed eraser that literally makes anything disappear. But instead of getting in trouble, Mr. Mufflin and the students praise him for "freeing them all" and the eraser only makes him even more popular.
  • Riddle for the Ages:
    • What do Fanboy and Chum Chum look like without their masks? And what are their "secret identities"? The one time they took them off, we only saw them from behind, and by the time we see their front, the masks are back on.
    • Why do the boys live by themselves? And where are their parents?
  • Rubber Hose Limbs: Has happened occasionally.
  • Rule of Three:
    • Kyle's list of what will happen to Fanboy in "Speed Eraser" (just look at Fanboy's "Oh, Crap!" face throughout):
    • Yet later on, it's himself who gets erased.
  • Running on the Spot: Shows up quite frequently whenever someone is about to run away.

  • Sand In My Eyes: At the end of "Norse Code", Fanboy says, "I'm not crying, the vortex just threw something in my eye!" He has a similar line in "Moppy Dearest".
  • Scout-Out: The Man-Arctic Seal Cubs, which are a parody of the Boy Scouts.
  • Self-Deprecation: The show loves doing this to itself. For an example, they take a jab at the frequent use of Toilet Humor in "Little Glop of Horrors".
    Fanboy: Hey Kyle! It's pizza day! Come play pizza monkeys with us!
    Kyle: You two are... pizza monkeys? What do you do, throw your poopparoni?
    Fanboy and Chum Chum burst out with laughter
    Kyle: (sighing) I'm witty day after day - and this is what they laugh at.
  • Self-Induced Allergic Reaction / Save the Villain: Boog fakes an allergic reaction to breathing air so Fanboy and Chum Chum will let him inside their plastic bubble. The two fall for it, and immediately afterwards, Boog's allergy clears up and he proceeds to beating up Fanboy and Chum Chum.
  • Series Continuity Error: Quite a few, possibly because of production and broadcast orders.
    • A fine example would be in where "Bubble Trouble" features the boys as Man-Arctic Scouts graduating from Seal Cubs to Narwhals at the end and yet in "Camp-Arctica" (which was produced after "Bubble Trouble"), they are Seal Cubs again.
    • "I'm Man-Arctica!" shows the boys and others don't know Man-Arctica yet in earlier episodes they do.
    • Fanboy doesn't like studying as shown in "I, Fanbot"; in "Crib Notes" he doesn't know what studying is.
  • Series Goal: Kyle's is to get readmitted to Milkweed Academy.
  • "Shaggy Dog" Story:
    • A surprise one in "The Tell-Tale Toy". As it turns out, Chum Chum didn't want the Ultra Ninja at all — he was only interested in the box that it came in, and was going to give Fanboy the toy.
    • In "Crib Notes", Kyle casts a spell that will give him the answers to a test to be readmitted into Milkweed Academy, except it turns him into a baby and he must go to sleep to know the answers. Fanboy and Chum Chum try various methods to make him sleep, and when they finally succeed and Kyle takes the test, his answers are voided because he didn't use a No. 2 wand.
    • In "Kids in the Hall", Kyle desperately tries to give Professor Flan his essay to be readmitted to his Milkweed Academy, but hall monitors Fanboy and Chum Chum keep getting in his way. In the process, Kyle's essay gets eaten by a three-headed dog from another dimension, forcing him to hand in a drawing on a sticky note. To Kyle's surprise, Flan likes the drawing so much that he accepts Kyle back to Milkweed... until he gets eaten by the three-headed dog.

  • Skyward Scream: Fanboy has one in "Stan Arctica" when he reads a comic about Man-Arctica being defeated by the Global Warmer and falling into a black hole.

  • Spoiler Title: Subverted, but the title card for "Speed Eraser" has Fanboy erasing Kyle's body with the magic eraser he has been given. This is exactly what happens to him in the actual episode.
  • Stab the Salad: The lunchladies have a habit of acting mean and threatening when they're actually trying to do something nice.
  • Stage Magician: Fanboy is The Great Fantini in "Lord of the Rings".
  • Stating the Simple Solution: In "I, Fanbot", Fanboy switches brains with Oz's robot so he can become a robot himself and be smarter; when asked why they didn't just put the robot's brain in his own body, Fanboy claims if they did that then he wouldn't have the "robot claws" the robot came with.
    Chum Chum: Robot claws!
  • Status Quo Is God: At the end of "A Bopwork Orange", Boog has learned not to bop, but to zap; after that, he retains his bopping obsession.
  • Sting: Lampshaded in "The Great Bicycle Mystery" the first few times it occurs. Fanboy notices it and tries to make it happen again by saying "One of you is a culprit in the great bicycle mystery!" although it does not play.
    Fanboy: Nothin'? Huh, I guess we should get to it then.
  • Sudden Videogame Moment: When the boys are trying to catch the monkey in "Gameboy", the animation style changes to 8-bit graphics.

  • Take Our Word for It: The show uses it sometimes, for example in "Little Glop Of Horrors", when the Necronomicon "vomits" the glop. The camera cuts away to the kids sitting at the table. After a while, Kyle walks into the shot, covered in the glop head to toe.
  • Talk Like a Pirate: The kids in "Fanboy A'hoy" all do this, although they go in and out of it.
  • Teacher's Pet: Kyle is one in "The Book Report of the Dead," and after Mr. Mufflin becomes a zombie, Fanboy replaces Kyle as "suck-up."
  • That Poor Cat: The show uses this sound effect quite a bit.
  • This Ain't Rocket Surgery: In "I, Fanbot" where Fanboy swaps brains with a robot.
  • Time Passes Montage: In "The Great Bicycle Mystery", Lenny's eight hours at the Frosty Mart are shown during a quick montage with many recurring characters passing across the screen.
  • Toilet Humor: An entire episode is centered around this.
    • Quite a few episodes like to throw in a poop or fart joke somewhere.
    • When Kyle has to lay an egg to cure his chicken pox, he says "coffee and a bran muffin ought to help things move along."

    • From "Marsha, Marsha, Marsha":
    Fanboy: You're the best number two I've ever taken on a mission.
    • In "Sigmund the Sorcerer", Sigmund refers to Kyle as "Kyle the Constipater" (as opposed to Kyle the Conjurer) several times throughout the episode, and jeers, "You push and push, and all for nothing!"
  • Token Evil Teammate: Though not technically evil, Kyle is this in Fanboy and Chum Chum's class, being more snarky and despising over their kooky and wild behavior. He's also the least friendly.
  • Tomato in the Mirror: In "Monster in the Mist", Boog stares at a video game for so long that his eyesight becomes poor, and sees what appears to be a scary monster which is really Fanboy with Chum Chum sitting on his head. Naturally, it takes until the end of the episode for the boys to realize they were the monster the whole time.
  • Total Eclipse of the Plot: In "Marsha, Marsha, Marsha", Fanboy tries to avoid taking a nap in kindergarten by opening the window shades to let sunlight into the room, but a solar eclipse occurs immediately afterwards.
  • Training Montage: In "Eyes on the Prize", Oz trains Fanboy and Chum Chum in the art of finding prizes in cereal boxes. Lampshaded at the beginning of the sequence when they punch through a cereal box called "Montage Munch".
  • Traveling-Pipe Bulge: The Frosty Freezy Freeze makes a bulge in the straw.

    Fanboy: Cat marks the spot!
  • Twinkle Smile: Boog gets one in "The Frosty Bus".
  • Twitchy Eye: Lenny gets a "stress twitch" whenever he's especially annoyed by Fanboy and Chum Chum, in which his enitre face contorts. Francine has one in another episode.

  • Uncanny Family Resemblance: Chum Chum has a female cousin named Muk-Muk. Looks like him with pigtails.

  • Unsportsmanlike Gloating: Fanboy, Chum Chum, and Boog all dance around while chanting "How you like us now?!" at the end of "Prank Master".
  • Vampire Hickey: Parodied in "Fangboy". Fanboy gets a mosquito bite on his neck and mistakes it for a vampire bite, leading to him believing that he has become a vampire. Later, Fanboy and Chum Chum meet a real vampire, Dr. Acula, who spends the rest of the episode trying to bite Chum Chum and ends up biting Fanboy's scalp by mistake. As it turns out, Dr. Acula had bitten Fanboy before, leaving bite marks on his neck on the side opposite from where the mosquito bite is. Fanboy asks himself how he missed the real vampire bite marks.
  • Vague Age:
