Yarna d'al' Gargan was the corpulent, six-breasted dancer who performed in the court of Jabba the Hutt. She, alongside dancers Oola, Rystáll, Lyn Me, and Greeata, gyrated for the Hutt's amusement.
Yarna was the daughter of a powerful Askajian tribal chief. While in her late twenties, Yarna was kidnapped on her homeworld, and sold into slavery to Jabba the Hutt. Unlike the unfortunate girl chained to the bloated Hutt, Yarna had a fair amount of freedom within the palace. However, she too was forced to undergo several changes to please her new master. While she had initially been skinny and very beautiful, Jabba had her fattened up, much to her dismay. In addition to this, Jabba forced Yarna to wear several layers of wart makeup so that she would remind him of an attractive female Hutt. She was also forced to wear a large headdress which looked like long hair that had been washed in wet garbage. Jabba dressed her in a costume to conform to her large body, partially cover her six breasts, and a long, rough skirt that would cover the majority of the dancer's legs. While claiming that her name meant "pretty" in Basic, Yarna had become quite "ugly."
While Yarna was allowed to freely socialize with the guests in the palace and do as she pleased, Jabba usually ordered her to dance with his current favorite slave girl when he wanted to watch his slaves dance. Exposing her thighs and bottom slightly, her Hutt master thoroughly enjoyed watching Yarna strut next to Oola on the dance floor, her breasts jiggling with her every sensual movement. Her entire body jiggled as she strutted across the room, exciting Jabba even more when she displayed any of her exposed skin that wasn't concealed by her clothes (which only added to the Hutt's lust for this dancer, even though he simultaniously watched Oola).
It is unclear if Yarna served other roles under Jabba's rule. She was mainly seen dancing and moving her big body around the dance floor for the Hutt, then was seen laughing and mocking Oola's demise shortly after. It is possible that she could have pleasured the Hutt in sexual activities, but seeing as Jabba preferred his personal slave girl above all others, that possibility was highly unlikely.
