[Sketchpad] follows the story of normal teenager, JD as he discovers a magic drawing book that randomly sucks him into another universe populated by every character he's ever drawn. Along with a group of toon pals, JD must bounce between his life in the real world (hanging with friends, homework, girls, etc.) and the toon world (beating villains and uncovering the mystery of why he was brought to the toon world). Action! Drama! Comedy! Platypuses? Sure, why not!
