The Mouse, the Bird, and the Sausage live happily together. The Bird brings home wood from the forest; the Mouse delivers water, makes the cooking fire, lays the table; and the Sausage cooks. One day, the Bird has a chat with some other birds. They make fun of the Bird, saying that it was doing all the work and that he was like a slave. The next day, the Bird suggests that they switch roles and refuses to go to the forest.
