Each night the zookeeper makes his rounds of the animal cages in the zoo. He wishes each animal a good night. This particular evening, unbeknownst to him, he is being followed by a gorilla who is unlocking each cage after the zookeeper passes by. There ends up being a parade of animals following the zookeeper back to his house to go to bed. Boy, is that zookeeper in for a big surprise. This is so fun and so funny. It's a great bedtime story for toddlers.
