In Humphrey's Mixed-Up Magic Trick by Betty G. Birney, the kids in Room 26 are talking about jobs they want to have when they grow up. Golden-Miranda wants to be a magician and, even more exciting, she wants Humphrey to be her assistant when she shows the class some tricks. But when one of her tricks is in trouble, can Humphrey's quick thinking (and scampering) fix it in time?
