Shaker, an R2-series astromech droid used for maintenance at the Drewwa spaceport, journeyed with Ben Skywalker on the mission to locate the Amulet of Kalara located on Ziost. As they searched, Shaker served as a moral compass for Ben, questioning his decision to abandon a young girl on a perilous world.
