Harpo, Verne's son with Angie. 1 year old. Marley is Angie's father, so he is Harpo's grandfather. Harpo has the best post-winter mane of all of them, besides Ziggy. But Harpo has more back-hair.
His snowy-white face comes from some impurities in his grandmother Lily who is surely part wool sheep and very large. I expect it to fill in with black as he ages, as Verne's face has. For having Lily and Marley as grandparents, Harpo is a good-looking animal. Verne's bloodline certainly contributed strongly to that.
