This book is 10 out of 10. There are 11 more books in the Captain underpants series. Book 12 is my favourite. Dav Pilkey books are also 10 out of 10 anyway my favourite part is when George, Harold and Captain underpants pass a litte boy and his mum. The little boy is awestruck to see a superhero in his undies with two random little boys. So I hope that gave you some useful information. It's a big thumbs up from me and I can't wait to see what Dav Pilkey comes up with next!
