Well, if a horse and an okapi likes each other very much...
Meet the horkapi. A small shy forest-horse. It has much the same high of a sheep, but is more slender. The horskapis live in small herds in the aquatorial forests. Their feeding on young trees and leaves, sometimes farn and bork.
Beeing shy and even tempered one had to be luck to see a horkapi. If threatend horkapis will always run away.
