Oola was a Twi'lek female dancer in Jabba the Hutt's palace, shortly before the Hutt's death. It was rumored that she was a member of the Tarkona clan, and was the sister of Nolaa Tarkona. She was brought to the palace by Bib Fortuna, in an effort to please Jabba. When she landed on Tatooine, she and her companions were intercepted Luke Skywalker, who offered to help them escape their coming slavery. Her companion, Sienn, chose to flee with Luke. Oola couldn't bring herself to scape, and was brought to Jabba. Fortuna fitted her with a leather headdress that contained large metal studs. These studs protruded on the inside of the leather helmet, clogging her ears and causing her undue pain. She was killed by Jabba's rancor after only two days of work, when she refused to submit to Jabba's demands. Jabba opened the trapdoor near his Hutt floater and let her drop into the Rancor's pit.
