The Polka-Dotted Horse

What if a winged horse landed outside your open window and made snorty horse-noises to wake you? It's not just his wings that make him astonishing. A spattering of different-sized polkadots decorate his coat like a party! The moonlight causes his extra long mane and tail to shimmer. The small horse is so white he dazzles. You flinch in total shock when he speaks, "Hello." You find out he is a great adventurer. He's like the Indiana Jones or Luke Skywalker of the horse world. Will you get to go with him? FLY? Might he have come especially for you?
