Wooof was a Nikto born and raised on Tatooine. He worked in smuggling and was doing well as a smuggler before he accidentally mucked up a job and found himself in debt to Jabba the Hutt. Later he is quite easily seen when Luke Skywalker falls into the Rancor pit. Even later he was piloting the Khetanna and attacked Luke when he came aboard the main deck but was killed when his blaster fire was deflected back at him.
