Unpaw's Fiend

Unpaw's Fiend is the most basic enemy you will encounter, he will run towards you and leap when you are close enough, after leaping he will fall and slide a little bit on the ground before getting up, as he moves he gets more and more momentum and speed, to leap he needs to get enough speed, if you are playing as any other character Unpaw's Fiend will do the normal half a heart damage but if you are playing as Unpaw he will deal a full heart of damage, when he takes enough damage his tail will fall off, without its tail it will start to bleed as it moves
