"Enemy In-Law" is a SpongeBob SquarePants episode from season four. In this episode, Plankton falls in love with Betsy Krabs.



Enemy In-Law 22

A giant robot is ravaging through Bikini Bottom, capturing the citizens and takes them to the Chum Bucket, where they complain when Plankton reveals he only wanted them to eat here and they leave. After that, Plankton gets into an argument with his computer-wife, Karen, and he eventually spots Mr. Krabs' mother, Betsy, walking out of the Krusty Krab. Plankton falls in love with Betsy upon seeing her for the first time. Karen gets mad upon hearing that Plankton's apparently in love with another woman, but after Plankton discovers that Karen has an off-switch, he turns her off.

Plankton and Betsy eventually start dating, and Mr. Krabs greatly disapproves of the relationship, convinced that Plankton is just trying to get the formula. He does his best to break up the relationship but only gets scolded by his mother.

Eventually, Mr. Krabs confronts Plankton at the Chum Bucket and accidentally gives Plankton an opportunity to find out the formula: as it would seem, Betsy actually does know the Krabby Patty-secret formula, as it's an old family recipe--Krabs claims that Plankton will never know since he's not part of the family. Then Plankton gets an idea to propose to Betsy Krabs and goes to the Krusty Krab to do so. However, Betsy turns him down, explaining that she's flattered but not ready for that kind of commitment. In addition, the robot Plankton created shows up, and it's revealed that Betsy is dating the robot. Plankton gets mad, and asks Betsy for the formula to call it even. Betsy realizes that Plankton was using her to be able to learn the formula, and punches him back into the Chum Bucket.

Plankton hits the on-switch for Karen, turning her back on, and they get into another argument. After Plankton insults Karen, she threatens him with a laser as he tries correcting himself. However Karen, who is still mad at him for turning her off before, zaps him anyway.

  • When Plankton calls Betsy, Plankton shows Betsy Krabs' number (Betsy Krabs' number is 791347).

  • Plankton says that he bought Karen. However, in "Single Cell Anniversary," he says that he built her.
  • In this episode, Mr. Krabs claims the Krabby Patty formula is an "old Krabs family recipe," though in the episode "Friend or Foe," it is revealed that Mr. Krabs created the recipe at a young age by accidentally knocking a shelf of jars into a vat of patty beef.
  • Plankton calls Karen a Wired Integrated Female Electroencephalograph. An electroencephalograph is a machine used to conduct electric activity in the brain.
