Quite the spontaneous bachelor, Harley takes any chance to toss a compliment someone's way, though he has taken a particular liking to Caribou. That's not to say he doesn't receive the occassional flirt back. In fact, he's caught the eye of a growing group of mares and stallions alike. Harley enjoys making smalltalk with just about anyone, though some horses do seem to be envious of the attention he draws. He's popular among the yearlings as 'that one cool uncle' that sometimes shares the tricks up his metaphorical sleeve.

He's also known as the escape artist of the herd, somehow finding a way out of every stall or paddock to the extent that the stable staff are willing to let him run loose, knowing that no matter how many times he escapes, he never strays far.
