Fed up with being constantly bathed by their mother when they want to play, the Marsupilami Triplets decide to run away from home. Lead by the mischevious scammer, Bobo, they decide to go to the one place where their parents would be least likely to look for them: The Moon! As the Marsupilami Parents and Hector search the jungle for them, and quickly pick up on the trail, the triplets have several misadventures in one night trying to reach their high expectations. Hector turns his hot-air balloon into a model globe as part of a lunar simulation that might help the small marsus realize how important their home and family is.
