What is "tunda"

The Tunda is a myth of the Pacific coastal region of Colombia and Ecuador, and particularly in the Afro-American community of the Chocó department, about a shapeshifting entity, resembling a human female, that lures people into the forests and keeps them there.

It is capable to change its shape to appear in the form of a loved one, as in the likeness of a child's mother, to would lure its victims into the forest and feed it with shrimps (camarones peneídos) to keep it docile. This is called entundamiento and a person in this state is entundado(a).

Her shapeshifting abilities are said to be imperfect, as this doppelgänger of sorts would always have a wooden leg in the shape of a molinillo, or wooden kitchen utensil used to stir hot drinks such as chocolate or aguapanela. The monster, however, is very cunning when trying to hide this defect from its would-be victims. In other versions, it appears to male loggers or hunters working deep into the jungle as a beautiful woman that tries to lure a man away, so it can reveal its hideous nature and suck his blood or devour him as a wild animal.
