On your way to the Gorge Crash Site on Koboh, you’ll encounter a Pit Droid whose ship has sunk into the nearby tar pit. Make a note of his position, as once you’ve acquired the Force Lift skill during the story, you’ll be able to come back and use it to rescue the ship from the pit. Do this, and the Pit Droid will be grateful for your help - talk to him afterwards, and he’ll join you at the Pyloon’s Saloon cantina, which also counts towards the Max Capacity   trophy.
