Urdruua, a Hutt crime boss operating on Nar Shaddaa, typically had a Gran aide by his side. In the era of the Clone Wars, he sought revenge against Aurra Sing for a prior offense against his family, attempting to assassinate her. His attempts involved various strategies, such as deploying poison gas, hiring mercenaries, and using smart mines. However, Aurra Sing evaded each of these dangers and then triggered a comm-pack she had previously delivered to him. The resulting explosion eliminated Urdruua, his assistant, and everyone within his palace.
