The robot is probably a parody of R2-D2 from the Star Wars franchise. Unlike R2-D2, he actually talks but R2-D2 whistles and beeps. Patrick enjoys the robot at first, but he constantly offers a massage, much to Patrick's annoyance. He calls Patrick "Master." Much Like Karen, Plankton's computer wife, he has a waving line when he talks, unlike Karen however his line is white and hers is light green.
