Drillo was an acquaintance of the curmudgeonly prospectors Gido and Gulu, who had been living in Rambler's Reach Outpost on the planet Koboh for a considerable amount of time. By the year 9 BBY, Drillo had met his death in an accident involving a gorocco, a strong predator native to Koboh, which he was trying to ride.
During a discussion with Cal Kestis, a Jedi Knight, in 9 BBY, Gido and Gulu mentioned Drillo as one of their dead friends, as part of their effort to demonstrate their past attempts at forming friendships.
The video game Star Wars Jedi: Survivor, developed by Respawn Entertainment in 2023, featured an optional dialogue sequence in which Drillo's name was brought up.
