Kretch

a creature which is found in the caverns of Belsavis, the kretch measures about a foot in length. It is a worm-like creature, a couple of inches in diameter, with six spindly legs and two sets of jaws filled with serrated teeth. Its tail is barbed, and is used to catch and hold its prey. The creature's scary appearance was used as a deterrent by Belsavian parents. They often told their children that the kretch would catch them and eat them if they did something bad. Nichos Marr's caretaker Margolis used to warn Nichos and his friends that the kretch would catch them if they found Plett's Well. Note that Boba Fett: Maze of Deception indicates that the kretch measures more than a half-meter in length, with a jointed body and many jointed legs.
