When does ChalkZone return?

The series follows Rudy Tabootie, an elementary school student who discovers a box of magic chalk that allows him to draw portals into the ChalkZone, an alternate dimension where everything ever drawn on a blackboard and erased turns to life. Rudy is joined in his adventures by Snap, a wisecracking superhero Rudy once drew with chalk, and Penny Sanchez. The series ran on Nickelodeon from March 22, 2002, to August 23, 2008, with 40 episodes in total.
Rudy Tabootie (voiced by E. G. Daily) is a 10-year-old, fifth-grade boy who loves to draw. One day while in detention, Rudy discovers a piece of chalk that allows access to the ChalkZone, a place where everything and everyone that has ever been drawn and erased by chalk takes form as living or is tangible. He soon makes friends with Snap (Candi Milo), a short, blue, humanoid drawing made by Rudy when he was only 8.
