The Traîcousse, also known as Trécouche (pronounced tré-coutche) is a vile creature that can be found lurking in the ponds and waterways of the Southwestern Ardennes and the Semois, especially Hautes-Rivières in France and Bohan in Belgium. As a water bogey, it is invoked to discourage children from entering rivers.
In appearance the traîcousse is most like a large crab, a meter in diameter, with a flattened, rounded body covered with palm-sized brownish scales. Its bloodshot eyes are the size of a human fist. Its mouth is huge and bristles with sharp shark-like teeth, while countless pincer-tipped legs allow it to move and grasp its prey. In some areas the traîcousse has become an ugly river witch.
The deepest part of the river, where the current is fastest, is where the traîcousse lives. It digs itself into small cavities and rocky ledges as it waits for prey to come near. Anything that approaches is seized and dragged under, never to be seen again. Missing livestock, fishermen, and children are its doing.
Every now and then the traîcousse will vomit up the skin and bones of its prey, which rise to the surface in a macabre mix of foam and blood.
