Harry and his class are headed to the zoo. It should be a super fun day! Unfortunately, Harry trips and accidentally unlatches the monkey gate. Fifty monkeys escape and are swinging all over the zoo, causing chaos everywhere! Harry thinks he can use one of his superhero inventions to get the monkeys back into their habitat, but maybe Harry will have to use his super smarts to save the day! This early chapter book from the Superhero Harry series includes a glossary, discussion questions, writing prompts, and bios.
