Tann Gella was a female Twi'lek slave who along with her twin sister Ann Gella were purchased by the Dug podracer Sebulba from the Hutt crime lord Jabba Desilijic Tiure. In the year 32 BBY, she and her twin were with Sebulba on the planet Tatooine where he planned to take part in the Boonta Eve Classic race out of Mos Espa spaceport. Prior to the start of the race the twins help the Dug prepare, with one filing his toenails and the other massaging his shoulders while he sat with his podracer in the Mos Espa Grand Arena's hangar.
