National Geographic Channel - Original Air Date: 3/5/11
Pat Spain goes to the Amazon looking for the mapinguari -- either a beast or an evil spirit, which the show describes as a one-eyed monster(with a sideways face), slashing claws, a noxious stench, a mouth in its chest, and a savage howl. It also supposedly protects the forest from clearcutters. To ingratiate himself to the locals, Pat undergoes a ritual involving being stung by bullet ants (so called because the sting feels like being shot). Talking to witnesses, Pat theorizes that a giant anteater may be responsible for at least one attack. Another scientist theorizes that the beast could be a giant ground sloth (supposedly extinct). Pat does some call blasting, and gets a reply (which sadly does not show up on their audio). He also gets a witness to pick the giant sloth out of a lineup. Interesting theory, but next time I hope we'll have more evidence.
