In one of the very first classes of my Illustration Class with Frank Stockton, he gave us a text about a beast to illustrate in three hours.
These cannibalistic forest spirits live in the upper Amazon and are called BORARO ("the white ones") by the Tukano Indians. BORARO are huge, hairy-chested demons with long legs and enormous phalli.
