Everyone's favorite classroom pet is now starring in chapter books! Humphrey is one happy hamster. He lives in Room 26 at Longfellow School. He has a big comfy cage with a wheel perfect for spinning and a room "full "of friends. But when Humphrey goes to Mandy's house one weekend, he learns that her hamster has something Humphrey has never seen before--a hamster car! Humphrey wants one, too, but school is not usually the place for toys.
