All day long, cheerful cloud people in the sky make cute and cuddly babies, such as human boys and girls, kittens, puppies, and other creatures, and give them to storks for delivery to the expectant parents.
However, one lonely gray cloud named Gus has the task of creating animals who are cute, but not so cuddly. His delivery stork named Peck gets the worst of it, being bitten by a crocodile, butted by a bighorn sheep, and pricked by a porcupine.
When Peck sees that his next delivery is to be a baby shark, he grows more than a little fearful, and flies away. Feeling rejected, despondent, and angry, Gus unleashes a brief thunderstorm, then begins to cry with rain pouring from below him.
