Buggane

The Buggane is a variation of the Boggart from the Isle of Man. They have bestial bodies, taloned hands, sharp teeth, and large heads. They’re thought to be shapeshifters that take the form of large calves, horses, or dogs. They live primarily in the water, near waterfalls and ponds, and only go on land to hunt.
