I liked the book because it was silly and the silly part was that one of the guinea pigs didn't like parties. My favorite part was when they had a race. Almost all of the guinea pigs hurt themselves. My favorite character was Fluffy. He was one of the guinea pigs and he was so cute. The characters reminded me of mice.
I would recommend this book to other kids that are in first or second grade because the pictures are really good. They look like kids' drawings. I think that when you read it you are going to like it.
