Li’l Sebastian fans, meet his real life counterpart: Acer, the miniature horse. At 22 inches tall, the 3-year-old Aquinas is one of the smallest horses in Britain. He lives on Wolfscastle Miniature Horse Farm, where he spends his time with other small steeds and relaxes in his stable, complete with a custom miniature door. Acer even has a best friend on the farm: the owner’s labrador named Demon. The two make an especially handsome pair.
