The little gorilla steals the zookeeper's key. And now the zoo animals follow their keeper all the way to the bedroom. "Good Night, Gorilla" is a wonderful picture book for the youngest readers. It is delightful to see how the little gorilla takes the key from the zookeeper and then the zoo animals, from the elephant to the armadillo, follow the tired keeper into the bedroom. And if not all of them had responded so politely to his wife's "Good night, dear," they might have been able to stay there as well.
