Curupí
Mythical being from Guaraní traditions. According to the legends, it is a stocky though not very tall individual, with enormous whiskers, green teeth, and very large genitals. It is said to usually walk on all fours and to have its feet pointing backwards.
It feeds on human beings and generally prefers to devour children and women. Another of its habits is to surprise travelers who venture into the jungle by sucking their blood.
