It's bedtime at the zoo and the zoo keeper is locking the animals up for the night and wishing them goodnight. But the gorilla has pinched the zoo keeper's keys and he'd rather sleep in a comfy bed than in a cage!
Peggy Rathmann was born in Minnesota and graduated from the University of Minnesota with a degree in psychology. 'I wanted to teach sign language to gorillas,' she says, 'but after taking a class in signing, I realized what I'd rather do was draw pictures of gorillas.' She then studied children's illustration in Los Angeles. She now lives in California.
