Dragon Ball Z: Atsumare! Gokuu World

They are both interactive, quiz like anime that were meant to be used with Bandai's Terebikko system. There's a small story throughout that gets interrupted by the characters pretending to call you, the viewer, on a phone and asking basic questions about what to do or what the answer is! The questions aren't too challenging if you know the source material so if you enjoy watching shows with audience participation, check them out!
