Mickey, apparently shipwrecked, is on a raft; he washes up on a tropical island, where a banana tree takes care of his hunger. He then discovers a piano that washed ashore, and begins playing it. The animals come around; a gorilla, after playing a 4-hands piece with his feet, destroys the piano. Mickey runs away and accidentally wakes a lion. The lion chases Mickey to a stream, where he jumps onto a rock that turns out to be right next to a crocodile.
