* BalloonBelly: The end of "Cookie Dough". Apparently Frankie's grandmother's cookies are irresistable enough to turn her into a temporary BigEater with a side of crazy that causes Frankie to gain quite a big belly.

* BalloonBelly: The end of "Cookie Dough". Apparently Frankie's grandmother's cookies are irresistable enough to turn her into a temporary BigEater with a side of crazy.

* GRatedDrug: Her grandmother's cookies. Let's just say it's best that she never catches wind of them.

** Most obvious when it comes to Madame Foster's cookies, which serve as a GRatedDrug.

* TrademarkFavoriteFood: Goes absolutely insane for Madame Foster's chocolate chip cookies, to the point of locking herself in her room for days while binging on them, as seen in "Cookie Dough."

* FreudianExcuse: A story in the 37th issue of ''Cartoon Network Block Party'' revealed that the reason he's obsessed with things being neat and tidy is because Madame Foster once blamed him for a mess she made and he didn't want to get into trouble by continuing to neglect messes.

* HeroesWantRedheads: His crush on Frankie.

* HeroesWantRedheads: His (very shallow compared to Mac's) crush on Frankie.

* TheBully: Sometimes. He can be quite domineering to others, [[WithFriendsLikeThese even to Mac]].

* BrainyBrunette: Hee's got a head of brown hair and is quite intelligent and responsible for a boy his age.

* BrainyBrunette: A head of brown hair and is quite intelligent and responsible for a boy his age.

* JerkassBall:
** Madame Foster holds many of these throughout the series. A prime example would be stealing the airplane tickets from Mac to travel with her friends at the end of "Foster's Goes to Europe". Many fans agree that was probably her lowest point in the series.

* WhyDidItHaveToBeSnakes: Has a fear of dogs in "Who Let The Dogs In?", due to him being based on a prey animal. So great is his fear that [[OOCIsSeriousBusiness he even called out "Frankie" instead of "Ms. Francis"]].

* DitzyGenius: Coco has the ability to lay eggs that contain anything she imagines, and she has a fairly logical and strategic mindset when it comes to emergencies. When there's a problem that needs solving, her eggs more often than not hatch into things she and her friends might need to solve that problem. However, she's very eccentric and has a medely of unusual quirks of her own.

* {{Expy}}: Think [[WesternAnimation/EdEddnEddy Eddy]] if he got turned into a VideoGame/PacMan ghost.

* DisappearedDad: We never see or hear anything about Mac's dad--the only relatives of Mac's that we see are his [[BigBrotherBully older brother]] and their [[WhenYouComingHomeDad mom]].

* OutOfFocus: Not in the show, but in the merchandise. Whenever merchandise of the series is released, expect Cheese to take his place (except for one shirt with both him and Cheese on it, and at least he did get a stuffed animal and figurine of himself).

%%zce* VitriolicBestBuds: With Bloo. Not in the pilot, but in the rest of the series.

* AccessoryWearingCartoonAnimal: He walks around with just shoes and socks on his feet and a wristband on his right wrist. [[LampshadeHanging He even mentions this to Eduardo]] in "Land of the Flea" when the latter feels embarrassed for being naked after Bloo shaves his fur off to make a robe because it has fleas on it.

A lofty, one-armed imaginary friend who loves sports and tries his best to be nice to everyone and gain acceptance from his peers. [[CatchPhrase Is that okay?]]

* CatchPhrase: "Is that okay?" and "Sorry!"

* {{Hypocrite}}: Throughout ''Store Wars'', Bloo berates Coco for not having any money and because of this, she has no say in anything. This is despite Bloo himself being poor and the money he had are actually from his friends.

One of the two main protagonists of the show. A creative, smart, and very warm-hearted 8-year-old. Bloo is his imaginary friend and his complete polar opposite, though they've been as close as can be their entire lives despite their differences.

* TheUnsmile: In one of the few cases of his smiling ever being shown in the series, he tries to assure Frankie and the others that her decision to [[spoiler: let World out of his box]] in ''Destination Imagination'' is a good idea. And then his mustache curls up, reveals his bunny buck teeth, ''and'' a full set of normal teeth beneath in a rather unnerving grin. [[OutOfCharacterMoment The gang actually get somewhat terrified by him simply smiling.]]

One of the two main protagonists of the show. A creative, smart, and very warm-hearted 8-year old. Bloo is his imaginary friend and his complete polar opposite, though they've been as close as can be their entire lives despite their differences.

* BalloonBelly: She's actually really self-conscious about it.

* BerserkButton: To say Wilt is not a fan of height jokes would be a gross understatement. The usually apologetic and outgoing guy [[OutOfCharacterMoment wishes for Bloo to get beat up, ''to Bloo's face'',]] because Bloo told a bad one in passing to a newcomer in "Beat With a Shtick".

* AttentionWhore: If anyone's attention is somewhere else, he'll do ''everything'' he can to bring it back to him.

* BerserkButton: Wilt is not a fan of height jokes, enough so to [[WhatTheHellHero call out Bloo for having made one]] and, in a major OutOfCharacterMoment, encourage he get ''beat up by the new guy'' as payback for it in "Beat With a Shtick".

* TheLoonie: There's no rhyme or reason to what she does or mumbles. It's not clear if she's just doing it for laughs or she's just insane.

* AlmightyJanitor: She has to answer to Mr. Herriman and Madame Foster, but she basically runs the entire house all by herself. And as it turns out her pay check is actually ''larger'' than Mr. Herriman's.

* TheSmartGirl: Coco may be rather eccentric, but she is by and large the cleverest person in Mac's friend group. Quite often, she intelligently uses her eggs to solve a variety of problems.

A bird-like imaginary friend who's able to lay an infinite amount of colorful plastic eggs that can hatch into absolutely anything. However, she can only say and write her own name (or variations thereof) [[{{Cloudcuckoolander}} and exists in her own universe independent from the other imaginary friends and humans]], but she's very kind and easygoing, and even surprisingly intelligent and resourceful.

* HandyFeet: She has no arms so she essentially uses her feet as a substitute for her hands.
