The Mahwot is a monstrous creature that makes its home in the Meuse River snaking through the Ardennes^*. A lizard-like amphibious monster the size of a calf, it runs back and forth on the bottom of the river from Revin to Liège and back. It has been sighted at Revin and Givet on a July night in 1870.

Its primary purpose lies in keeping children away from the water. As an aquatic bogey, it will not hesitate to pull in and devour any child foolish enough to play too near the Meuse.

The mahwot rarely leaves the water. Its appearance on land is believed to be a bad omen, presaging death, war, or pestilence. More importantly, it will haul itself onto land at the beck and call of angry mothers to eat naughty children. As the warning in the local dialect goes, “V’la le Mahwot, si tu n’ti tais nai, d’ji vas t’fouaire mandjie!” (“Here’s the mahwot, if you don’t shut up right now, he'll eat you!”). The phrase is effective.
