Hidebehind

The Hidebehind is a nocturnal fearsome critter from American folklore that preys upon humans that wander the woods, and was blamed for the disappearances of early loggers when they failed to return to camp. As its name suggests, the Hidebehind is noted for its ability to conceal itself. When an observer attempts to look directly at it, the creature quickly hides behind an object or the observer and therefore cannot be directly seen. The Hidebehind uses this ability to stalk human prey without being observed and to attack without warning. Their victims, including lumberjacks and others who frequent the forests, are then dragged back to the creature's lair to be devoured. The creature subsists chiefly upon the intestines of its victim and has a severe aversion to alcohol, which is therefore considered a sufficient repellent. Tales of the hidebehind may have helped explain strange noises in the forest at night. Early accounts describe Hidebehinds as large, powerful animals, despite the fact that no one was able to see them.
