Mapinguari
The Mapinguari is a giant hairy cryptid of Brazilian Amazon folklore (Tupi-Guarani mbaé-pi-guari: 'thing with twisted feet'). Described as monkey-like, bipedal, with backwards feet, a single eye (forehead or belly), a vertical mouth from nose to stomach, and foul odor. Bulletproof except at navel. Devours human heads. Linked to extinct ground sloth (Glossotherium) folk memory by Oren (1993).
