Humphrey's a hamster and a class pet who lives in room 26. He loves all the kids in class with him and he loves going home with them on the weekends. He also Has some silly problems that you and me know how to solve easily but hamsters are small and can't always do what we can do. There are 3 other books in the series I think this is the forth book. It doesn't matter if you read them in order though I had a little trouble figuring out that Humphrey was a class pet. If you don't like complicated then you should read the books in order. If you like funny and confusing books then you would definitely like this book.
