When Billy Bixbee finds a tiny dragon in his bedroom, his mom tells him, "There's no such thing as a dragon!" This only makes the dragon get bigger. He grows, and grows, and grows, until he's bigger than Billy's house--and that's just the beginning! A funny, madcap story and playful illustrations by beloved author-illustrator Jack Kent pair in a book that will have children wondering if maybe friendly pet dragons do exist after all!
