The Things That Left Their Skin is a short story written by William Pauley III. It was originally published in the anthology Toe Tags: 21 Spine-Tingling Tales from the Best New Authors of Horror.
It is about a man who takes his date to a seemingly long-abandoned carnival. They find that it is inhabited and when he wins prizes (false tattoos), they go home thinking it was odd, but otherwise harmless. When the tattoos begin to take a life of their own, they find themselves in a terrifying situation.
