Blocky
For blocky digital images, see Image resolution#Resolution of digital images.
Blocky is a child-like drawing that Rudy drew early on. He may be primitive, but he does have a heart of gold. He sort of looks up to Snap like an adoring younger brother.

ChalkDad
ChalkDad is a caricature of Rudy's father Joe, and he first appeared in the Oh Yeah! Cartoons pilot episode Chalk Dad!.

Skrawl
Skrawl is the villain and in all of his appearances, his schemes involves of taking over ChalkZone. Skrawl was voiced by Jim Cummings. The character first appeared in a self-titled episode at the end of the show's first season. He built up an art museum dedicated to Rudy in order to lure the artist into his trap. After Rudy was misled into placing his Magic Chalk in an airtight glass, Skrawl revealed himself to Rudy and all of the Zoners, and then signalled for his cronies, "the Beanie Boys", a pack of moronic singing henchmen wearing propeller beanies, to pick up the building and drop it into the Wait 'N Sea. During the course of this, Skrawl revealed his back-story. Rudy was trying to draw a chalk drawing at a party, but had so much difficulty with it that he wound up getting some help in what resulted in Skrawl. Although several kids had contributed parts to his design, Skrawl blames Rudy for making him the hideous-looking thing that he is. Despite Skrawl's attempt at getting away in a rocket ship (which Rudy had designed) as the Beanie Boys dropped the building, Rudy was able to outwit him and escape. Skrawl claimed that Rudy hadn't seen the last of him, and the character appeared in numerous episodes afterward.

Queen Rapsheeba
Queen Rapsheeba has been a semi-regular since the Oh Yeah! Cartoons short "Rapunzel". In the short, she played the title role in the Globe Theater's stage production of the same name. But this particular performance was almost ruined by a freshly-drawn thundercloud that destroyed the set. Fortunately, Rudy Tabootie drew up a new set, and Rapsheeba's biggest admirer, Snap, volunteered to play the part of the Knight (seeing how the guy playing the part ran off). Both her speaking and "rapping" voices are provided by Russi Taylor (credited in the Oh Yeah! Cartoons short as "Rosslyn Taylor".

Rapsheeba often appears to host big festivities in ChalkZone, such as car shows and hoedowns, which Snap will attend only if she's there.

It is unknown if Rapsheeba really feels about Snap the same way he feels about her, considering her apparent vanity. However, Snap often rescues her performances when she needs his help most. Also, she appears to swoon for him at one point in the half-hour episode "Double Trouble" and on occasion refers to him as "her man".
