Austin is a robot repairman in Mega City, where robots never seem to break down. Then Uniqua calls and says Robot Reba is broken and on a rampage--she won't stop making cookies and refuses to share her cookies with anyone. Then, one robot after another has a breakdown. Professor Bug (Pablo) announces that he is controlling all of the robots, and he's going to rule Mega City! Can Austin and Uniqua save Mega City?
