Mahwot/Karnabo

The Mahwot, later called the Karnabo, is a monster thought to live in the Lower Meuse Ardennes in France. It is described as an amphibious creature as large as a calf and shaped like a lizard. It rarely leaves the Meuse, and it foretells disaster and destruction. It is thought to come when mothers call for it to attack disobedient children. It is known to make a nasal sound that paralyzes and suffocates people who get too close, and it kills cattle. Later iterations had a human face, eyes like a basilisk, and a trunk-like nose. It is often thought to be locked away in an abandoned slate quarry.
