A lighthearted fantasy rather like an updated The Biggest Bear. In the beginning, Bigtooth is a ""tiny, shiny, green baby...[with] the sweetest little alligator smile""; Joshua catches him while fishing. Parents and neighbors predict the inevitable, and, sure enough, Bigtooth gets huge. Joshua tries to hide him in the boathouse, but he comes out when Joshua's parents throw a party--a fish fry--to honor the full moon. Consternation ensues when he's joined by a crowd of other huge gators from the river, but it turns out they just want to join in the dancing, after which they all depart--Bigtooth, too. This will never replace Lynd Ward's masterpiece, but it's smoothly told and has nice touches of humor, while the brash, cartoon-style illustrations are full of color and verve.
