Droofus the kindly dragon has a price on his head, but the small boy who befriends him refuses to sell him to the king.
Droofus the not-so-bad dragon is generally at peace with the world, and is kind to smaller animals. As a nice guy, he's not interested in laying waste to the country-side, even though some people expect him to. As with all Peet's books, the faces on his animals are wonderfully expressive, yet still look like real animals (one of my favorite things about all of his books which I've read).
"Children will enjoy this amusing combination of fantasy and realism, and especially the cheerful illustrations of a likeable dragon."—School Library Journal
