They have quite some lovely equines, although I remember admiring the Friesian quite a bit. Depending on how you're hoping to face the world of Star Stable, (if it's any consideration to invest in buying a horse/pony that reflects what you would personally enjoy on the game, such as more Western or English-based riding activities), one type of breed may be more suitable over another.
Play around with colors and combinations and see which ones you like. c:
