"Karen 2.0" is a SpongeBob SquarePants episode from season 8. In this episode, Plankton upgrades to Karen 2, so his first Karen leaves and gets a job at the Krusty Krab.



At the Chum Bucket, Karen dumps a bag of chum onto a tray and zaps it into a three course meal, with the entree being chum pot pie. She goes to Plankton, who works on a project. Annoyed, he tells her the pot pie chum was supposed to be a stir fry chum, and she responds that her memory is full. Plankton says such problems will be solved by his newest creation, which he reveals to be Karen 2. Karen is distraught that Plankton is replacing her, and his words anger Karen to the point where she tries to zap him. He flees from her blasts, but Karen 2 shuts her off via the Chum Bucket's power source. At the Krusty Krab, it is closing time, which makes SpongeBob sad. Mr. Krabs walks home as SpongeBob follows him and says goodbye until he trips over a box filled with Karen's components. Mr. Krabs is about to get away until SpongeBob points out the "free" computer. Mr. Krabs rushes back, feeling anything free should be taken.

They go back to the Krusty Krab, where they activate the computer, who turns out to be Karen. SpongeBob is wary that it may be one of Plankton's schemes, but Mr. Krabs is convinced that anything free is automatically good. When Karen's startup is completed, the screen turns to a hysterically crying face. SpongeBob tries to comfort her, but he unintentionally makes her even more depressed. Karen looks out the window of the Krusty Krab, where she sees Plankton and Karen 2 having a romantic dinner at the Chum Bucket. She angrily says she never wants to see Plankton again, and Mr. Krabs welcomes her to the Krusty Krab crew.

The next day, Squidward walks in to see Karen is at his post. He is baffled until Mr. Krabs explains that she will be doing his cashier duties for free. Squidward jumps for joy at the thought of no longer working at the Krusty Krab and dealing with SpongeBob or customers, but his joy is quashed when Mr. Krabs reassigns him to restroom duties. Unfortunately, Karen is still upset, even snapping at a customer who requests a Krabby Patty. A knocking is heard at the front door: it is Karen 2, who repeatedly slams into the front door. Plankton pops out from inside her, asking what is wrong, and she tells him he did not program her with arms. Plankton sees Karen at work, and becomes uneasy, then a wave of customers pushes him and Karen 2 into the Krusty Krab. Karen and Karen 2 argue, reaching the point that Karen jumps out of her post, ready to fight Karen 2. Mr. Krabs uses the opportunity to make money from people betting on the fight.

Karen and Karen 2 fight, striking each other. When Plankton falls out of Karen 2, she accidentally runs him over and crushes him, and Karen is horrified. Karen 2 is unconcerned, which infuriates Karen, who finally destroys her replacement. She talks to a wounded Plankton, who sees the error of his ways in replacing her. Karen's power runs out, and Plankton takes the battery from the destroyed body of Karen 2 and puts it into her. Plankton begs Karen to wake up and promises that he will never take her kindness for granted ever again. Karen reactivates, thinking it was all a dream. She and Plankton return to the Chum Bucket, and Karen 2's screen explodes. Mr. Krabs is upset over the loss of Karen 2, but when SpongeBob suggests that he rebuild her, he has Squidward wearing Karen 2's screen like a mask and taking orders, because "the kids love robots," as the episode ends.

The building toy playset.

  • This is the first episode in the entire series where Karen is the main character.
  • In 2020, a building toy playset based on this episode (pictured right) was released. It is modeled after the scene where Mr. Krabs reactivates Karen in his office, and the set includes Karen, Mr. Krabs, and his desk.
  • The title card font is the same along with its color as the one used for the episode "Komputer Overload."
  • This episode marks the second time Plankton replaces Karen with another machine; in "Komputer Overload," Plankton blames Karen for his repeated failures to obtain the secret recipe and builds three machines to help him with that task.
  • This episode marks the second time Karen works at the Krusty Krab. The first was in "Bucket Sweet Bucket."
  • This episode marks the third time Karen has zapped Plankton. In "Enemy In-Law," after he is dumped by Betsy Krabs and tells her she "crawled back" to him, and once more in "Frozen Face-Off," she zaps him for leaving her nearly dead in the frozen tundra.
  • This is the third episode in which Plankton replaces Karen with another love. The first was "Enemy In-Law," and the second was "Komputer Overload."

"Krusty Karen" comic strip.

  • In Comic Crazy: Take 2, there is a comic strip called "Krusty Karen" that shares a very similar plot where Karen leaves the Chum Bucket and works for the Krusty Krab. However, Karen 2 is not in that comic.
  • When Karen is depressed because Plankton is cheating and she starts working, she does not ask for the Krabby Patty formula because she is mad at Plankton and does not want to help him.
  • When Karen 2 says that Plankton did not design her with hands, she seems to have hands when she disconnects Karen's hard drive. However, this is only one arm.
  • Usually people push the Krusty Krab door open, but this time it is pulled.
  • When Karen and Karen 2 argue, they use computer terms against each other. When Karen says she will "crumble" Karen 2's cookies, it is an actual computer term; cookies are files that contain information about a user that are sent to the central computer with each request. The server uses the information to customize data sent back and to log the requests of the user.
