* AdoredByTheNetwork: Creator/CartoonNetwork gave this a huge buildup: a "sneak peek" six days before the premiere (which also aired on Boomerang and streamed on the website), a countdown bug on-screen the day ''of'' the premiere, and at least one rerun a day for the entire week afterward.
** The Latin American version of Cartoon Network brings this trope UpToEleven. They went to such extent to dedicate a whole day to the show. They also use them to announce the new stuff of the month and air reruns '''three''' times a day, everyday, and they often air clips of this show during the commercial breaks for no reason at all.
** Cartoon Network also put a lot of faith into the show by renewing a second season a week before the premier, though this could have been done as the show spends a long time in production. Cartoon Network later renewed the show for a fourth and fifth season before the third season had even started airing.
* TheDanza: The character Teri (the hypochondriac paper bear) is played by Teresa Gallagher. Given Teri is just a supporting character and Gallagher also voices one of the main cast, this was probably a coincidence.
* DawsonCasting: With the exception of the Watterson children[[note]]The initial voice actors for Gumball (Logan Grove), Darwin (Kwesi Boakye), and Anais (Kyla Raw Kowalewski) took the roles at approximately the age of 12, 11, and 9, respectively. About three years later, Gumball and Darwin were recast for the third season: Gumball's new voice actor (Jacob Hopkins) was 11 and Darwin's (Terrell Ransom, Jr.) was 10. Anais's original voice actor continues to voice her even as she enters her teens.[[/note]], the kid characters are played by adults.
* DescendedCreator:
** Sussie's model and first season voice actor is Aurelie Charbonnier, one of the show's storyboard artists and the creator's girlfriend. Her screams and laughs are provided by the show's creator and Charbonnier's boyfriend, Ben Bocquelet. As of season two, Fergus Craig is now the voice of Sussie on the rare times that Sussie speaks coherently, though Aurelie's chin is still used for the character and Ben Bocquelet still does Sussie's screaming and laughing.
** Billy Parham (the blue, egg-shaped boy) is voiced by Richard Overall, the show's voice director and one of its editors. He also performed some of the songs that weren't sung by a character, such as "Because We're Men" in "The Mustache".
** Mic Graves, the series's director, voices Banana Joe, Banana Bob, and the voiceover heard through "The Voice" [[spoiler:which is actually William the flying eyeball's internal monologue]].
* DevelopmentGag:
** "The Mystery": The yearbook pictures for Alan and Tina both use their designs from the Early Reel.
** The class photo in "The Curse" that gets impaled by pencils stuck into it uses the Earl Reel designs for everyone but Darwin and Gumball.
** "The Fridge": Nicole puts war paint on her face. The way she does it covers her whiskers, making them look longer, and thus more like they did in her character model before it was redesigned for the second season.
** "The Skull": When Clayton shapeshifts into Banana Joe's form, he looks like Joe's first season character model instead of his current one.
** "The Bumpkin": Gumball tries to escape school by [[CatapultToGlory sitting on one side of the seesaw while Hector stomps on the other]], the same thing he and Darwin did to try and escape from the school in the pilot.
** "The Storm": Masami's crush on Alan is funnier when you realize that they were a couple in the pitch pilot "Gumball."
** "The Tape": The group shot where Gumball almost [[TitleDrop says the show's name]] is very similar to the end of [[https://www.youtube.com/watch?v=W7uDvSITrlY one of the series's trailers]], except that was in front of the Watterson house and everyone managed to say it.
** "The Void": Darwin's CGI design from the pitch pilot (titled "Gumball") can be seen floating around, as can a rejected design for the Watterson house.
* {{Defictionalization}}: [[Website/YouTube Elmore]] [[FictionalCounterpart Stream]] is now real...[[http://www.youtube.com/user/ElmoreStream sorta]].
* FakeAmerican: Most of the cast besides the voice actors for Gumball, Darwin, and Anais are British, Scottish, or Irish voice actors doing AmericanAccents. Technically averted with Dan Russell (the voice of Richard, Mr. Fitzgerald, Coach, and Tina in the first season), and Sandra Dickinson (the voice of Granny Jojo, Hector the giant's mother, the pink cupcake lady, Felicity), who are American actors based in the UK. Similarly, numerous characters are voiced by Kerry Shale (Bobert, Hector, Leslie, Larry, Sal Left Thumb, Harold; Alan and Idaho in the first season), who is Canadian and currently living in London.
* FanNickname: Penny and the rest of her family are often called "doe-nuts" (because they're peanuts and she has antlers).
* FlashbackWithTheOtherDarrin: A flashback in "The Name" redubs a scene from the first season episode "The Curse" with Gumball's third season voice actor. The same goes for a flashback with Darwin in "The Extras" to the second season episode "The Sweaters".
* HeyItsThatVoice: Anais is [[WesternAnimation/AdventureTime Me-Mow]] (Kyla Rae Kowalewski).
** In Japan, Gumball is Creator/JunkoTakeuchi, a.k.a. [[Manga/{{Naruto}} Naruto Uzumaki]]. Cue Naruto jokes due of how Gumball sounds awfully similar to the titular ninja.
** Granny [=JoJo=] is Sandra Searles Dickson ([[Series/TheHitchhikersGuideToTheGalaxy Trillian]])
** The first voice of Darwin voiced Gossamer the monster on ''WesternAnimation/TheLooneyTunesShow'' and was in the Tyler Perry movie, ''I Can Do Bad All By Myself'' (Kwesi Boakye). His replacement voice (Terrell Ransom, Jr.) was on such American shows as ''Days of Our Lives'', ''The Middle,'' and ''Children's Hospital''.
** Creator/BrianBlessed is the homeless amnesiac drifter who is revealed to be [[ChristmasEpisode Santa Claus]] on the episode "Christmas."
** In the French dub, Richard (Papa) is the same voice actor used to dub [[WesternAnimation/RegularShow Benson, Muscle Man]], [[Manga/{{Naruto}} Gaara]], and [[WesternAnimation/TotalDrama Trent]] (''Total Drama'' version, not ''WesternAnimation/{{Daria}}'').
** In Brazil and Poland, Nicole's voice actress is the same one who voices [[WesternAnimation/JusticeLeague Wonder Woman]].
*** Interestingly, the Brazilian Nicole and Richard have mentored [[Series/{{Glee}} Rachel Berry]]; Richard used to be Rachel's high school teacher, whereas Nicole is her current dance instructor. [[note]]Nicole didn't date Finn Hudson.[[/note]]
** In Hungary and Italy, Gumball is [[WesternAnimation/ParaNorman Neil Downe]].
** Creator/DerekJacobi is the narrator in the episode "The Lie".
** In Russia, Tobias is [[WesternAnimation/PhineasAndFerb Baljeet]].
* IronyAsSheIsCast: Teresa Gallagher, Nicole's voice actor, is a professional singer and is the only main cast member who yet to have a singing part on the show.
* KeepCirculatingTheTapes: Unless you live in the UK or have access to Cartoon Network's UK channel, there's really no legal way to see the uncut version of "The Skull" where Gumball, Darwin, and Clayton give themselves shock therapy to stop lying or the version of "The Storm" where Gumball tells Carmen that he's not a "cheap, corruptible bimbo" instead of a "cheap, corruptible coward." Even digital sources like Hulu Plus and [=iTunes=], which keep the full opening and end credits and have seasons one and two available, include the edits in the US version.
* NonSingingVoice: Unlike other musical numbers Darwin is in (barring ones where it's obviously supposed to be a different voice like "No More Mr Nice Guy!"), "What He Thinks About Us!" in "The Words" is performed by a different voice actor than his usual one.
* TheOtherDarrin:
** Gumball was voiced by Nicky Jones (aka WesternAnimation/{{Chowder}}) in the early reel version of the show while Darwin was voiced by Jake Pratt.
** Between seasons 1 and 2, many characters changed voices:
*** Lewis [=MacLeod=] left the show entirely, so his roles were recast between Steve Furst (Principal Brown), Hugo Harold-Harrison (Ms. Simian and Rocky Robinson), and Dan Russell (the Doughnut Sheriff).
*** Rupert Degas also left, and his roles were passed to Adam Long (Mr. Small), Max Cazier (Clayton), Hugo Harold-Harrison (Tobias, one of the Eggheads) and Stefan Ashton Frank (Mr. Robinson).
*** As mentioned before, Aurelie Charbonnier was the original voice of Sussie in the show's first season (along with Ben Bocquelet providing the unintelligible screams, wails, and laughter of Sussie). From season two to the present, Fergus Craig (a British comedian) replaced Charbonnier as Sussie's speaking voice (while Charbonnier's chin is still used as the character and Bocquelet still does Sussie's screaming and laughter).
*** A few others changed voice actor despite their original voice actor still playing other characters: Alan the balloon and Idaho the potato went from both being voiced by Kerry Shale to both being voiced by Hugo Harold-Harrison; Carmen the cactus went from being voiced by Teresa Gallagher to being voiced by Alix Wilton Regan); Tina Rex went from being voiced by Dan Russell to being voiced by Stefan Ashton Frank.
** Both Gumball and Darwin were recast in season three from Logan Grove and Kwesi Boakye to Jacob Hopkins and Terrell Ransom, Jr. respectively due to their original voice actors hitting puberty and sounding too old for their roles. The season three premiere "The Kids" is both a farewell to Grove and Boakye and an introduction to Hopkins and Ransom, Jr.
** In the third season, Rocky went from Hugo Harold-Harrison to Simon Lipkin and Jamie the bully went from Jessica [=MacDonald=] to Maria Teresa Creasey, but Harold-Harrison and [=MacDonald=] still voice other characters.
** Almost all voices were recast in the Hungarian version after season 1, save Gumball, Darwin, Nicole, Anais and a few side characters. Season 3 changed even more voices, including Gumball's and Nicole's. Now Darwin, Anais, Banana Joe, and Penny are the only characters with their original voices.
* PropRecycling: A lot of the characters are rejected advertising mascots Ben Bocquelet had in his portfolio.
* SeriesHiatus: Likely because of its multi-medium format and how much time it spends in production, episodes of ''Gumball'' take about one-and-a-half times as long to come out as for most cartoons of similar length, which is why there can be anywhere from three weeks to a couple of months between new episodes in the same season.
* ShortRunInPeru: Several times the series has gone on [[SeriesHiatus an extended hiatus]] in the middle of a season, leading episodes to premiere in other countries before reaching U.S. and U.K. audiences:
** UK[[labelnote:*]]Given the show is made ''in'' the UK, but with the US as its primary audience, one could debate whether episodes premiering in the UK are examples of this trope or the only ones where this trope does ''not'' apply.[[/labelnote]]: "The Mystery", "The Microwave", The Meddler", "The Fight",
** Spain: "The Virus", "The Pony", "The Hero", "The Dream", "The Sidekick", "The Photo", and "The Storm"
** Middle East and North Africa (Arabic dub): the last nine episodes of season two (from "The Promise" to "The Finale")
** Chile: "The Oracle"
** Latin America: "The Safety" (which was shown with the original English dialogue and not dubbed in Spanish)
** Portugal (Portuguese dub): The last four episodes of season three ("The Downer", "The Egg", "The Triangle", and "The Money")
* TalkingToHimself:
** Hilariously, both Principal Brown and Ms. Simian were voiced by Lewis [=MacLeod=] in the first season, despite them being ''lovers''.
** Richard has had scenes where he talks to Mr. Fitzgerald, the Doughnut Sheriff (after season one), and the Ripley 2000 manager (the little, periwinkle teddy bear seen on "The Refund" and "The Question"), all of whom are voiced by Dan Russell.
* TroubledProduction: The show's production had a rather rocky start because few of the staff had worked on a television show before. This resulted in major organizational restructurings and numerous delays that the show's creator is thankful for not getting in trouble for.
* TheWikiRule: [[http://theamazingworldofgumball.wikia.com The Amazing World of Gumball Wiki]]
* UnfinishedEpisode: Four episodes [[https://twitter.com/benbocquelet/status/247455074387886081 were scrapped]] in the first season: two were called "The Mom" and "The Pizza", the other two weren't named. Season two also had an episode planned called "The Rex" which was [[https://twitter.com/benbocquelet/status/397840050152804352 cut because it would have gone over budget.]] However, the premise for the two named episodes may or may not have been for the season three episodes "The Mothers" and "The Pizza". "The Rex," which would have fully introduced Tina's father and have been a parody/homage to ''Jurassic Park'', has, so far, been scrapped.
* WhatCouldHaveBeen:
** Most of the characters of this show were originally going to be mascots for ads and company logos, but all of them were rejected. Penny, [[https://vimeo.com/68915551#t=30m40s for instance]], came from a commercial pitch to Nickelodeon and had ''a gun''. Rather than get rid of them or redesign and repitch them in the hopes they'd be accepted, Ben Bocquelet superimposed them on a photograph of a school and decided to create a TV series out of it.
** In [[http://issuu.com/worldscreen/docs/tv_kids_mipcom_2013 an interview (page 127)]], Ben Bocquelet revealed the show was originally envisioned as being about a remedial school for rejected cartoon characters. Daniel Lennard, the Vice President of Cartoon Network's European division, [[https://vimeo.com/68915551#t=3m06s found the idea to be too depressing]], so Bocquelet revised it to also focus on Gumball and his family (as the network was looking for family shows and "kids-in-school" shows) and turned the remedial school into an American junior high school. He also mentioned at one point hoping Creator/AdultSwim would be interested in some of his work, although, contrary to some claims, [[https://twitter.com/benbocquelet/status/557632076636499969 he never pitched Gumball itself to Adult Swim]].
** The idea for Darwin's origin, a fish that grew legs, [[https://vimeo.com/68915551#t=16m40s originated in]] an earlier show pitch by Bocquelet about a village of [[OurCryptidsAreMoreMysterious cryptids]] isolated from the rest of the world.
** [[http://www.kidzcoolit.com/interviews/the-amazing-world-of-gumball-hag-cons-questions-for-creator-ben-bocquelet.php The show's name]] was originally planned to just be "Gumball" and not refer to any particular character. It was then decided to make that the main character's name, and from there the title expanded to ''The Amazing World of Gumball''.
** Gumball and Richard were [[https://vimeo.com/68915551#t=12m40s at first both thought up as blue dogs]], but they figured a family of cats and rabbits [[RuleOfCute would be cuter]]. Gumball was then going to be a black cat, [[CatStereotype because]] he's [[BornUnlucky very unlucky]], but it was decided this would limit the stories he could be involved in and make him visually indistinct. [[http://polyminthe.blogspot.com/2012/06/amazing-world-of-gumball-development.html Some early sketches of blue dog Richard and black cat Gumball]] have been posted.
** An "Early Reel" was made for the show as a pilot. The most noticeable differences are the fact Darwin was animated in CGI and Gumball had a square head, though other characters looked different too. Teri was also a boy, there.
** The people in "The Sweaters" from Richwood High [[http://theamazingworldofgumball.wikia.com/wiki/The_Sweaters/Gallery#Miscellaneous were originally going to be]] {{Funny Animal}}s like everyone else, rather than stiffly animated 70s/80s-cartoon-style humans.
** Sarah G. Lato's name was originally going to be [[http://theamazingworldofgumball.wikia.com/wiki/File:GB200_DOLLY_ORIGINAL_PUPPET.jpg Dolly]].
** "The Downer" [[https://twitter.com/benbocquelet/status/578723490926370816 underwent a significant rewrite]] because the initial draft was consider far too dark. Bocquelet [[ShrugOfGod refused to elaborate]] on how the first and final scripts differed, and, when asked for some storyboards, said that it was up to the storyboard artist to release that information. He would, however, later describe it as being "[[https://twitter.com/benbocquelet/status/618190542619459584 just lame]]".
* WorkingTitle: Some episodes changed name mid-production:
** "The World" was at one point named "The Objects".
** "The Extras"[[note]]season three episode where the background characters overtake the show[[/note]] was originally titled "The People"
** "The Fraud"[[note]]the one where Principal Brown is revealed to have a fake diploma[[/note]] was originally called "The Phoney"
** "The Void" was originally called "The Hole".
** "The Boss" [[note]]the one where Rocky takes a job with Chanax, Inc so he can make his father proud[[/note]] was originally called "The Heart"[[note]]no word as to why it was changed, but it can be assumed that Mr. Robinson was originally going to have a heart attack instead of get so mad that his head split open and his stuffing fell out[[/note]].
** "The Question"[[note]]the one where Gumball and Darwin find the meaning of life after being one with the universe during a sugar rush[[/note]] was originally "The Answer".
* WriteWhatYouKnow: The turtle drying out in "The Puppy" when Darwin leaves him in the sun is based on how the pet turtle of the series creator died.
* WriteWhoYouKnow: Ben Bocquelet [[https://www.youtube.com/watch?feature=player_detailpage&v=Swxzs2NRpDI#t=130 has described]] Richard, Nicole, and Anais as caricatured versions of his family members that they're named after and Gumball as being based on his perception, as an adult, of what he was like as a kid[[labelnote:although]]Between different interviews, Bocquelet has expressed ambivalence as to how much Gumball is based on himself. In [[https://vimeo.com/68915551#t=8m30s one video]], Bocquelet said he considered Gumball more of a character, ''another'' staff member said Gumball reminded them of Ben often, and Bocquelet sheepishly emphasized that he's not ''that'' stupid.[[/labelnote]]. Darwin [[https://vimeo.com/68915551#t=15m45s was inspired by several childhood friends]] that spent so much time at Bocquelet's house that they felt like members of the family. [[http://www.kidzcoolit.com/interviews/the-amazing-world-of-gumball-hag-cons-questions-for-creator-ben-bocquelet.php One, named Paul]], was also bald and had a similar personality.
* XMeetsY: This show is best described as ''TheSimpsons''[[note]]The Wattersons, like the Simpsons from seasons one to five, were a semi-dysfunctional family that most of the townspeople tolerated at best and wished they would move away/be put in jail/die at worst. Also, some of the jokes and storylines on the show have been done on ''The Simpsons'', but here, they're shorter and try to go for something different/more family friendly[[/note]] meets ''RegularShow''[[note]]in that the characters are anthropomorphic animals and objects, it often has MundaneMadeAwesome stories, and has a main character in a romantic relationship with a shapeshifter[[/note]] with the aesthetic of ''Film/WhoFramedRogerRabbit''[[note]]the animated characters in a live-action setting, only ''The Amazing World of Gumball'' uses photographs, not live-action footage -- except for the antique appraisal show on "The Watch", the weather report on "The Law," and the news report about the crime wave on "The Pizza"[[/note]] and possibly ''WesternAnimation/DrawnTogether''[[note]]different types of animation styles coming together, only ''Drawn Together'' stuck with 2D animation styles from different studios and styles (Princess Clara was a spoof of Disney's princesses, specifically Ariel and Snow White; Toot Braunstein was a spoof of BettyBoop and the 1920s black and white rubber-hose cartoons made by Fleischer Studios; Captain Hero was a spoof of the stylized, GoldenAge 1940s Superman cartoons also made by Fleischer Studios; Foxxy Love was a spoof of the 1970s Hanna-Barbara cartoons that have teenagers/20-somethings, some of which had bands, solving mysteries, like ''Scooby Doo, Where Are You?'' ''Jabberjaw'', and ''Josie and the Pussycats''; Wooldoor Sockbat was a spoof of the loose, wacky cartoons made famous by Tex Avery, Bob Clampett, and John Kricfalusi [with a bit of ''SpongeBobSquarePants'' thrown in], Xandir was a spoof of video game animation, Ling-Ling is a spoof of anime [specifically Pokemon and Digimon], and Spanky Ham was a spoof of stiffly-animated, crude-humored adult cartoons found both on- and offline, a lot of which are animated with Adobe Flash), while the animation styles of ''The Amazing World of Gumball'' range from 2D traditional to 3D realistic and even include puppets, claymation, 8-bit graphics, and stop-motion all superimposed over live-action photos[[/note]]

!!General Trivia:
* After the first season, Anais, Darwin, and Gumball has one, two, and three front teeth, respectively.
