Molly Lou Melon is short, clumsy, has buck teeth, and has a voice that sounds like a bull frog being squeezed by a boa constrictor. She doesn't mind. Her grandmother has always told her to walk proud, smile big, and sing loud. She takes that to heart, but when Molly Lou has to start in a new school, a horrible bully picks on her on the very first day. Molly Lou Melon knows just what to do about that.
