The Grumpasaurus is a small, fearsome creature. You should observe the Grumpasaurus from afar. Edward Hemingway’s book is written as a field guide and features diagrams and colorful illustrations. The book starts out with the Grumpasaurs finding his teddy bear with his arm falling off. It sets him off in a grumpy mood. Eventually his teddy bear is repaired and we soon learn that the Grumpasaurus is a young child in a bad mood. This is definitely for younger audiences. It could be a fun way to talk about bad moods and strong emotions.
