Muddle (a duck) and Mo (a goat) are best friends, but Muddle is a bit confused about what type of animals they both are. Fortunately, during the course of their walk together, long-suffering Mo helps Muddle get his duck identity sorted out in this warm and funny tale of friendship, differences, and acceptance.   "...this comforting entrée into the world of differences hits the right marks for the intended age group." —Booklist   "This short and goofy book with themes of identity and friendship is fun to share one-on-one or in storytime." —School Library Journal   "A simple story with sweet illustrations that make this an easy entry for very young readers." —Kirkus
