Curupira

The Curupira, Currupira or Korupira (Portuguese pronunciation: [kuɾuˈpiɾɐ]) is a forest spirit in the myth of the Tupí-Guaraní speaking areas in the Brazilian and Paraguaian Amazon and Guyanas. It is a guardian of the rainforest that punishes humans for overcutting.

The Curupira notably has feet pointing backwards allowing it to leave a backward trail of footprints, and by this confusion and other supernatural means causes the traveler to lose his way.

It is often said to look like a short-statured tapuio or caboclo (civilized indigene or one of mixed race), but also said to be a bald but otherwise shaggy man (though the women have flowing hair). Some say it has blue or green teeth. The red-haired image has become fixture, perhaps due to conflation with the caipora.

The Curupira according to early Jesuits was a feared being known to leave gruesomely scarred bodies, to be appeased by offerings. But it underwent a mutation via European influence, and was recast into more of a mischievous trickster type spirit, often bungling and letting humans outsmart it, though it could still cause misfortune and death.
