I like this book, because it is non-fiction. I liked the character Stomach Acid, because he was funny. The story reminds me of The Magic Schoolbus- The Human Body, because they go into stomach acid. I think it is the best book I've ever read! It's a great book, it's non-fiction, it has great illustrations.
I recommend this book to the whole school. First through fifth grade would lik this book.
