Summary and Uses: This book is about a little boy who transforms into different things as his mood changes throughout the day. When he goes a little too far, he discovers his parents transform too. I think this book is geared for older children. I read it to a five year old and he wasn't enchanted by the story. The idea of this book is hilarious and I would read it out loud to a third, or fourth grade class.
