Plankton is sick of his computer "wife" Karen, Plankton spots Mama Krabs and falls in love with her. Plus, he turns off Karen. Convinced that this just another trick aimed at getting the family formula for Krabby Patties (which was not), Krabs tries to reveal Plankton's schemes and break up the ill-favored fling. Krabs decides to break up that fishy relationship before he winds up with the world's tiniest stepfather and before Plankton finally gets the secret formula for Krabby Patties. While accusing Plankton for the "scheme" he reveals to Plankton that his mother knows the secret recipe giving Plankton an opportunity. However, the robot (Plankton had created) causes the downfall of their relationship and finds out about Plankton's scheme after he tells her. Then, he gets flung out of the Krusty Krab by her and Karen gets turned back on as he bounces off the "on" button. Plankton insulted her and she threatens him with a lazer, Plankton quickly corrects himself but Karen (who is still mad for turning her off) zaps him anyway.
