Carl is forced to hand out candy for Halloween, but makes use of C2 to handle it for him so that he can get to Skye's party. Unfortunately, C2 believes that everything is free on Halloween and ends up helping a burglar (mistaking him for a trick-or-treater) rob a store! Mr. Agar spots him, and he's about to tell the police. Will Carl escape the arrest AND save C2 from the burglar in the house all in one night before the 'rents get home?
