* AwesomeMusic: You wouldn't expect a show as cute as this to have [[http://www.youtube.com/watch?v=XZaSFLVa1PM such a badass opening theme.]]
* BaseBreaker: When concerning Snap, it all boils down to whether or not you like him.
** The music video segments. Fans either love them, hate them, are indifferent, love some but hate others, or liked them more when they were in the target audience.
* BizarroEpisode: "The White Board Zone". It has a plot [[MindScrew too screwed-up]] to explain but all we know is that in the end [[spoiler: it was all just a dream]].
* CanonDiscontinuity: The only Oh Yeah! short not to be shown on the show proper, "Chalk Rain". Also notable because it featured a fact about Chalkzone that never was mentioned again: the rain in Chalkzone is the chalk sidewalk drawing being washed away... [[DepartmentOfRedundancyDepartment by the rain]].
** Despite this, a clip of it still appears in the intro.
* EarWorm: The theme song, by far. To a lesser extent, the Accordion Worm song.
** The 1-minute music video songs run a close second.
** Skrawl's song. After two or three variations of it, it will never leave your head.
* EnsembleDarkhorse: Skrawl.
* HilariousInHindsight: Here, we have a property involving a person creating whatever he wants using a special writing utensil... No, wait, I'm [[BaitAndSwitchComparison thinking of]] [[{{Scribblenauts}} something else]], nevermind.
** [[WesternAnimation/ThePowerpuffGirls Buttercup]], one of Elizabeth Daily's most popular roles, has an episode where she destroyed the chalk of her sister, Bubbles. This becomes ironic in [=ChalkZone=], where Rudy Tabootie, who is also voiced by Daily, pretty much has chalk as his main weapon.
** [[WesternAnimation/FostersHomeForImaginaryFriends This wouldn't be the only show featuring a little boy and his blue best friend who he made up]] that Candi Milo (Snap) would star on (she was not the voice of Bloo, but she did voice Coco, Madame Foster, and [[FountainOfMemes Cheese]])
*** This is taken even further in the Japanese dubs of both shows- Makoto Tsumura voices both Rudy and Mac.
** When Snap masquerades as a foreign exchange student in "Snap Out of Water", he claims to be from Greenland. Reggie responds with, "[[Film/MeanGirls If you're from Greenland, why are you blue?]]" Since this was one of the original shorts on ''WesternAnimation/OhYeahCartoons'', it would be five more years until ''Mean Girls'' was released.
** The show got a soundtrack in February 2003 entitled ''In The Zone'', and was released under Jive Records (which Nickelodeon was releasing its' soundtracks under at the time). Jive would release another album [[BritneySpears of the same name]] later that year in November.
* [[GermansLoveDavidHasselhoff Japanese Very Much Enjoy Chalkzone]]
* MemeticMutation: "Rudy's got the chalk!"
** Various [=GIFs=] of Rudy drawing the portal with the text "Fuck this shit, I'm going to [=ChalkZone=]" have appeared often on Tumblr.
** As are "why friendzone when you can [=ChalkZone=]?" jokes.
* {{Misblamed}}: Fans of ''WesternAnimation/InvaderZim'' complained that this show replaced their favorite show. While in reality, [=ChalkZone=] was delayed for two years. Not to mention that ''Zim'' was still running during the first season of the show.
** It's also been misblamed for being a rip-off of the 1970s British cartoon ''Simon in the Land of Chalk Drawings'' (which later aired on Nickelodeon in 1979 and throughout the '80s as part of ''Pinwheel''). Co-creator Bill Burnett stated in a recent interview that ''[=ChalkZone=]'' was ''never'' meant to be a rip-off of the show- in fact, he had never even heard of it until after ''[=ChalkZone=]'' finished production.
* {{Moe}}: The main trio. Actually, the entire show is moe.
** Rudy's already a cute kid, but he's even cuter as an eight-year-old in the first two ''WesternAnimation/OhYeahCartoons'' shorts.
** Rudy's two-year-old cousin, Sophie, who appeared in "The Terrible 2 1/2s", "Pop Goes the Balloon", and "When Santas Collide".
* MostWonderfulSound: Rudy singing. While all three of the main trio's voice actresses can sing very well, E.G. Daily (Rudy) is the only one who made a career out of it. Doubles as TheCastShowOff.
* NarmCharm: A lot of the music video segments could qualify. One example would have to be "Chunky", a rock song that features lyrics about...painting your room and going to the moon with chunky peanut butter. The lyrics in a lot of the songs are very goofy and cheesy, but the EarWorm quality mixed with Rudy, Penny, and Snap's voice actresses all being really good singers make them enjoyable for a number of fans.
* ScrewedByTheNetwork: Not only was the series premiere delayed for years, the last 6 episodes didn't air until 2008... a whole 3 years after the beginning of the final season. Even more, 2 additional episodes were planned but never aired at all.
** The show originally aired at 8:30 PM on Friday nights (for new episodes- repeats would air throughout the entire week) during season one and got extremely high ratings (even being the seventh highest-rated animated show for the 6-11 demographic and the fourth highest rated Nicktoon in 2002). Despite that, it took over a year for season two to air (to the point where some viewers had begun to think Nick canceled it after six episodes), and Nickelodeon moved the timeslot to 9:30 PM. While this may have worked for ''Invader Zim'', which was aimed at an older audience, ''[=ChalkZone=]'' was aimed at a younger audience than ''Zim'', and 9:30 PM is usually around the time the target audience would be going to bed. It got worse when Nick gave up all the show's airtime to more popular fare like ''[=SpongeBob=]'', ''The Fairly [=OddParents=]'', and ''The Adventures of Jimmy Neutron: Boy Genius'', leaving it with only its' 9:30 PM timeslot on Fridays and one timeslot on both Saturday (two if you count the show on Nick on CBS) and Sunday.
* TastesLikeDiabetes: Couldn't be any more sugar-overloaded even if it tried.
* TearJerker: For some, the song "Time to Go Home" due to being rife with EndOfSeriesAwareness (the episode it aired with was the last episode in production, however five episodes premiered after it)
* TheyWastedAPerfectlyGoodCharacter: Terri Bouffant after she became an antagonist in "Indecent Exposure", wanting to expose [=ChalkZone=]. Her only other appearance as an antagonist was in "Snap vs. Boorat". The show ended one episode later.
* UglyCute: Some fans feel this way about Skrawl
* UncannyValley: The titular character of "Skrawl's Brain"
** Robo-Rudy from "Double Trouble" is also pretty unsettling.
* ViewerGenderConfusion: Snap. The character is male, but the voice sounds fairly ambiguous to some people (being voiced by Creator/CandiMilo and all).
* VindicatedByHistory: When it was still running, ''[=ChalkZone=]'' was despised by a lot of older Nickelodeon fans. These days, you will find much more fans than haters.
* WereStillRelevantDammit: The show happened to be made about five years ''after'' everyone stopped using chalk for things like school boards, restaurants, and the many uses that seem to pop up in the show.
** Due to hipster baristas, shop owners and street artists, Chalk seems to be making a comeback.
* WhatDoYouMeanItWasntMadeOnDrugs: A show about the adventures of a child in a world made of chalk? ...yeaaaah.
* TheWoobie: Penny in "Mother Tongue"
