Dr. Seuss's The Sneetches

Once upon a time there were Star-Belly Sneetches and Moon-Belly Sneetches who lived together on the beach, until one day they decided they were too different to live together.

So they went their separate ways.

But then Stella, a Star-Belly Sneetch, met Pearl, a Moon-Belly Sneetch, and they realized Sneetches are Sneetches, and no one kind of Sneetch is the best on the beaches.
