One of Spec's least known cryptids, the mapinguari is said to be a large, feathered animal that stands up to 10 feet tall. Its distinguishing feature is its pair of claws, which are large and sharp enough to bring down a bull k'z'k tuskhorn (as reported by one person). Upon hearing the man trip, one of the animals, presumably a bull, reared up into a defensive position. Immediately, the group ran for their lives, with the animal chasing them half-way to the boat.
