Little Piglet and Little Lamb and Little Calf and Little Foal want to venture out of the farmyard and take a walk across the fields. "Don't get lost!" say their mothers. Little Piglet, Little Lamb, Little Calf, and Little Foal walk and walk and walk. They play chase and hide-and-seek and they race and they splash#151; what fun! They won't get lost! Or will they?
