When anything is erased from a chalkboard, it’s not really gone – it just enters a realm called the Chalkzone. And fifth grader Rudy Tabootie found a way to go there! With a piece of “White Lightning” chalk, he can enter the Chalkzone any time he likes. In the Chalkzone, Rudy befriends Snap, a bold superhero Rudy drew years ago. But Rudy soon discovers not every doodle is friendly.
While in detention, Rudy finds out about the magic chalk and he goes to Chalk Zone, a place where all the erased chalk pictures go to. He meets up with Snap, a picture of a superhero that Rudy drew in 2nd grade, and also this this monster that wants to hurt everyone. With Snap's help, Rudy is able to beat the thick headed monster.
Everyone comes back from Vacation and has to read their writing piece to the class. Rudy drew a comic book of his Chalkzone Adventures in Chalkzone. Rudy has to stay back after class and write a real story of his Vacation. Rudy then explains his story to the new girl, Penny!
Snap wants to go to the car show to see Queen Rapsheeba, only he doesn't have a car. That all changes when he gets a voice activated car that takes all of his commands (and figures of speech) literally.
Rudy brings his friend Penny to ChalkZone to help her find a formula, but Snap sees Penny as Rudy's girlfriend.
Penny and Rudy have to do a report on future inventions where they go into chalkzone. Then a robot, Craniac 3, sees Rudy drawing with the chalk, it tries to use the chalk, but fails (only humans can use the chalk). It takes rudy into the dome of the future, with all these useless and stupid inventions.
Hair eating frogs from Chalk Zone have invaded PlainsVille. Can Rudy and Penny send them back and save the hair of PlainsVille?
