As the sleepy keeper bids him good night, Gorilla snitches his keys; then he creeps after him, letting the other animals out. In a lengthening parade that includes a mouse first seen taking one of Gorilla's bananas, they pad along behind the keeper like faithful dogs, enter his house, and curl up to snooze in his bedroom; Gorilla snuggles into bed next to the keeper's wife. The man is too drowsy to notice, but she does; taking Gorilla by the hand, she leads the whole parade back to the zoo with an air of resignation that suggests this has happened before. Gorilla certainly knows the ropes; he and the mouse (still toting the banana) follow her back, this time to settle in the middle of the bed. The amiable cartoon characters, vibrant palette, and affectionate tone of the author's art recall Thacher Hurd's cheerful illustrations. Delightful. (Picture book. 3-7)"

School Library Journal

PreS-Gr 1-A mischievous little gorilla lifts the zoo keeper's keys on the first page of this sparely worded picture book. The brightly colored illustrations basically tell the entertaining story as the gorilla tags along behind the man, gleefully freeing all of the other animals, who then follow him single file into his neat little house. It is his unruffled wife who, without disturbing her sleepy husband, calmly returns the creatures to their cages. Even she, however, does not notice the wily gorilla, who, still in possession of the keys, returns to the house, slips into the big bed, and curls up contentedly between the people for the night. A clever, comforting bedtime story.-Jan Shepherd Ross, Dixie Elementary Magnet School, Lexington, KY

Horn Book

Joe the zookeeper, clearly a kindly man, tiptoes home after saying an affectionate, but sleepy, good night to all of his animals; he fails to observe that Gorilla has pinched his keys from his back pocket. In a book economical in text and simple in illustration, the many amusing, small details, as well as the tranquil tone of the story, make this an outstanding picture book.

ALA Booklist

In this limited-word picture book, a gorilla follows the zookeeper as he says good-night to his charges. What the zookeeper doesn't know is that the mischievous gorilla has snatched his keys and is letting out the animals almost as fast as the zookeeper can lock them up. The animals follow him to his house and into the bedroom, where, in an amusing pitch-black spread, a pair of worried wide-open eyes let the zookeeper's wife know that she and her husband are not alone. Jaunty four-color artwork carries the story and offers more with every look. (Reviewed July 1994)
