Everyone tries to categorize the remarkable creature, but while he may not know what he is, he knows very well what he isn't--a cat, a rat, a lion, a wild boar, a hippopotamus. Then one day he meets an equally unusual animal who accepts him for himself. "I know what you are," she tells him. "You are my friend." This sweet, simple story will gladden the hearts of all children who have ever felt "different."
