Marvin Wanted More!

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, 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, what went in is going to have to come out.
