When the zookeeper makes his nighttime rounds, one mischievous gorilla steals his keys and follows him, releasing the other animals from their cages one by one.

Under a moonlit sky, they parade silently behind the sleepy zookeeper and follow him into his house, where the keeper's wife discovers them and escorts them back to their beds.

Practically wordless, the book tells a delightful going-to-bed story with magical illustrations that will enchant your child.
