In a gray, boring city full of tidy, peaceful animals, Mr. Tiger is the only one who is not happy. He wants something different. He wants to walk on four legs instead of two. And he does not want that nice, stiff suit anymore. To everyone's despair, Mr. Tiger decides to become wild and leave the wilderness. There he is happy but also lonely. If he eventually decides to return to the city, it appears to have been following his action!
