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.
