I like this book because it is a mystery. You have to look for clues in the book to help you figure things out. I liked the way the author made the monkeys smart so the zookeepers had to figure out ways to outsmart the monkeys. They tried making traps for the monkeys using bananas. I got a lot of information about how to trap monkeys!
I recommend this book to kids who love to read mysteries. I think they will like reading about these funny monkeys. These monkeys are so clever, and it makes a good story.
