After watching a horror movie, the next day at work SpongeBob thinks that Mr. Krabs is a robot. SpongeBob soon convinces Squidward that Mr. Krabs is a robot, and the two think that robots are going to take over the entire sea. Then they both question Mr. Krabs, and try to make him admit that he is a robot. Finally they realize the truth, which is just how the movie ended. SpongeBob and Patrick find an abandoned clam and decide to take care of it. But they don't realize the responsibility they are giving themselves (mostly Patrick, who won't help SpongeBob).
