Okpe is a massive, quadrupedal ogre from Argentinian and Chilean Tehuelche folklore. He looks like a pig made of impregnable solid rock, without soft spots or weaknesses. Okpe preys on children, luring them with braised meat before carrying them off in a device on his back. Children captured by Okpe are taken into the jungle and devoured. Attempts to thwart his actions fail, as he is impervious to conventional weaponry.
Once Okpe abducted an older child, who had the presence of mind to hold onto an overhead branch and escape his captor. While Okpe sought his victim and screamed for him to return, the child ran back to his village. There a mare was butchered – as the Tehuelche do in emergencies – and its skin was stretched out on the ground. When Okpe trundled through in pursuit of the boy, he slipped on the stretched hide and fell so heavily that his stony armor rattled! Okpe started to cry in defeat, crying so hard that his tears caused a flood that went up as high as his teeth. He never bothered the Tehuelche again.
