Everyone's favorite sheep is back— now in a new book-and-audio-CD package! Marvin is not a happy sheep. All the other sheep are bigger than him, and can run faster and jump higher than he can. So Marvin decides to do something about it. He eats. And eats, and eats, until he is so big that there is nothing left for him to eat in the world—at which point Marvin eats the world itself! But that is a step too far, and what went in is going to have to come out. This is a rumbustious story that shows how it is possible to take some self-improvement just a little bit too far.
