Plankton told spongeBob that the robots kicked him out of the Chum Bucket, and the hero falls for the villains' lies and agrees to help him get back into the Chum Bucket. In the PC version for the game, after SpongeBob and Patrick go see Plankton who reveals to be behind the robotic invasion, Patrick fools around with the robot controls turning the machine off.
