In a drab, boring city full of neat, quiet animals, Mr. Tiger is the only one who is not happy. He wants something else. He wants to run on four legs instead of two. And he does not want that neat, stiff suit anymore. To everyone's dismay, Mr. Tiger decides to become wild and leave for the wilderness. He is happy there, but also lonely. If he finally decides to go back to the city, his action appears to have been followed!
