Things are just about perfect for Guji Guji and his somewhat unconventional family until the day three bad crocodiles appear. They don't see a family; they see "fat, delicious ducks." They don't see Guji Guji, the biggest and strongest duck in Mother Duck's family, either. "Look at yourself! No feathers, no beak, no big webbed feet! What you have is blue-gray skin, sharp claws, pointed teeth and the smell of bad crocodile. You're just like us." Poor Guji Guji. What's a crocoduck to do? An original in his own family, Guji Guji proves to himself and others that family, no matter where or what that family may be, is worth protecting and cherishing.
