When his friend, the tadpole, becomes a frog and leaves the pond to explore the world, the little fish decides that maybe he doesn't have to remain in the pond either. A tadpole and a minnow are underwater friends, but the tadpole grows legs and explores the world beyond the pond and then returns to tell his fish friend about the new creatures he sees. The fish imagines these creatures as bird-fish and people-fish and cow-fish and is eager to join them.
