A donkey, dog, cat, and rooster strike out on their own. The place where they stop to rest is a robber’s den, and they proceed to scare the snot out of the robbers by braying, barking, meowing, and crowing all at once. The robbers leave, but return, determined to regain their loot.
The animals beat them until they’re convinced that the place is filled with enemies. So the animals talk about starting a band called the Bremen town musicians but they don’t actually get around to doing it because they like the robber’s house and decide to stay there for a while.
