Rubber

A night spirit from Chilean folklore, described as a very tall man, with stiff and straight hair covering his head, "a giant muscular body and sharp claws" and with such a putrid smell that he can wake dogs. 

He is said to have "walked underground" during the day, going out at night to wander the beaches, attacking people from behind to rip out their eyes and kill them. 

For fear of attracting kavcho, the Alakalufs refrained from making bonfires at night in the open air.
