Sarla was the moniker that the criminal Wungo bestowed upon a barrel that was being stored on the Randomizer, which served as the flagship for the Riftwalkers pirate organization. Zilastra, who was the leader of the Riftwalkers, had assigned Wungo, together with his companions The Lobber and Ghor, to the seemingly unimportant job of repeatedly shifting crates within the Randomizer's hangar bay while being overseen by the assassin droid known as IK-111; this was presented as Wungo becoming a member of the Riftwalkers. When Kylah Lohmata, a member of the Riftwalkers, and Depa Billaba, a Jedi Master who had secretly joined the gang under the alias "Hotwire," entered the hangar, Billaba inquired about the duration of the crate-moving task. Wungo, who was at that time carrying the barrel, responded by stating that they had been doing it for such a long period that he had started giving names to the objects, and he then introduced Sarla.
