Congo's Caper is a platform game developed and published by Data East and is the sequel to Joe & Mac.
Congo and his girl Congette were two monkeys happily living in the jungle when a magic ruby fell out of the sky and turned both of them into half-humans. The ruby also set free a demon-kid who promptly kidnapped Congette. Now it's up to the newly evolved Congo to hurry through the jungle and rescue her.
