Wam Lufba, nicknamed Bam, is a weak yuzem, that was born on Endor. He was originally banned from hunting due to his size, and could only find a job as a spotter for a group of bigger yuzem. One day, a poacher captured him and the rest of the party were captured. They were taken to Jabba the Hutt, the crimelord was offended by the gesture and dropped them into his rancor pit. The rancor devoured a gammorean guard, but Wam grabbed a rifle and killed several guards before being captured. Pote Sniktin convinced Jabba not to kill him and instead he took Wam on as a junior exterminator. Later on when Jabba was killed, he settled down and started his own extermination business.
