Babies both human and beast are created up in the stratosphere, by the clouds themselves. One cloud specializes in "dangerous" babies, creating a challenge for his loyal stork that has to deliver them.

The stork delivers a baby elephant to Mrs. Jumbo, veteran of the circus, but the newborn is ridiculed because of his truly enormous ears and dubbed "Dumbo". After being separated from his mother, Dumbo is relegated to the circus' clown acts; it is up to his only friend, a mouse, to assist Dumbo to achieve his full potential.

The classroom is astonished when their teacher tells them his big secret: sometimes he turns into a frog. Two kids see it as their task to protect his secret.. and to keep him out of the beak of a stork.

Storks deliver babies...or at least they used to. Now they deliver packages for global internet giant Cornerstore.com. Junior, the company's top delivery stork, is about to be promoted when he accidentally activates the Baby Making Machine, producing an adorable and wholly unauthorized baby girl. Desperate to deliver this bundle of trouble before the boss gets wise, Junior and his friend Tulip, the only human on Stork Mountain, race to make their first-ever baby drop - in a wild and revealing journey that could make more than one family whole and restore the storks' true mission in the world.
