"Plankton's Intern" is a SpongeBob SquarePants episode from season 12. In this episode, Plankton needs help to steal the secret formula, so he hires an intern who knows more about Mr. Krabs than anyone else.



Plankton's Intern 036

Patrick clones himself.

The episode opens with Karen leaving the Chum Bucket to visit her motherboard. She tells Plankton she put up fliers for an intern, which leads many people to apply, but they leave after they hear about the sub-minimum wage portion. Patrick applies and tells Plankton that he wants to handle the science equipment, and proceeds to enter Plankton's Duplo Maker. Plankton instructs Patrick to place a coin inside the machine, but he walks inside the machine and creates countless clones of himself. Plankton kicks Patrick and his clones out of the Chum Bucket, and gets upset because no applicants are left.

Suddenly, Pearl shows up at the Chum Bucket and applies for an internship. Plankton is initially frightened by Pearl, but he grants her the internship after he realizes that she wants to help. After she accepts the job, Plankton decides to show off his new inventions. Unfortunately, all of his inventions fail and create gigantic messes. Plankton forces Pearl to clean the restaurant each time his inventions fail, which annoys her a lot.

At home, Mr. Krabs asks Pearl about her day. When Pearl complains and says that Plankton doesn't let her do any of the "fun stuff," Mr. Krabs tells her that a good employee always follows the boss' orders. She takes her father's advice and decides to continue working for Plankton.

The next day, Pearl visits the Chum Bucket and wishes Plankton a good morning. When Pearl asks Plankton if she can help with Plankton's science experiments, he asks her if she can materialize a Krabby Patty. Pearl says she can't do that, but proceeds to tell Plankton that she can give him the Krabby Patty secret formula because Mr. Krabs is her father. Plankton is very surprised by Pearl's statement and he decides to give her a promotion. He proceeds to ask Pearl if she is free to attend a conference later that night, and she says "Oh yes." Pearl goes home and prepares for her extra shift.

Plankton and Pearl sneak into the Krusty Krab.

Later that night, Pearl thanks Mr. Krabs for the advice and leaves her home to begin her extra shift. Pearl and Plankton proceed to sneak into the Krusty Krab, and they encounter SpongeBob "sleep cooking." When Plankton jumps on top of SpongeBob repeatedly, he hits Plankton with a spatula and places him inside a Krabby Patty. Pearl throws SpongeBob into the garbage can, and he later wakes up inside the garbage can. SpongeBob calls Mr. Krabs while SpongeBob's still inside the garbage can, and tells Mr. Krabs that "Plankton and a giant goon are trying to steal the secret formula!" Mr. Krabs gets angry and visits the Krusty Krab after the phone call.

After Mr. Krabs arrives at the Krusty Krab, he catches Plankton and Pearl attempting to steal the formula. When he questions his daughter about the situation, she explains that she was simply following her dad's advice. Mr. Krabs becomes annoyed at himself due to his "big mouth," so he tries to coerce Pearl into giving him back the formula. Pearl agrees to give her dad the formula back under one condition... Mr. Krabs has to triple her allowance. He reluctantly agrees, and Pearl gives Plankton a good old fashioned launch back to the Chum Bucket via her blowhole. The end of the episode shows Karen returning to the Chum Bucket, and she comes in to see the Patrick clones working around the lab.

Production notes[]

Ian Vazquez:

  • Vazquez said that the creature was "the first time [he] got to really change a character from the boards" and was "so glad they kept the hot pink lighting in this scene too!"[3]
    • They were also glad that the animation team made Plankton's eye reflection move as well.[7]
  • Vazquez said that in this episode, Plankton "was one of the easiest and most fun characters to draw, and [Mr. Lawrence's] line deliveries [were] a gift."[8]

  • When asked about the episode in April 2020 if Plankton's intern would be Pearl, he denied it, saying that Pearl is too young. He said this likely to not spoil any details about it, although at that point, the episode had already been leaked in South Africa 2 months prior.[9]
  • This is currently the only known episode of the series to have standalone supervising direction by Marc Ceccarelli.[2]
    • He previously wrote and storyboard directed (aka rough storyboarded) the season 9 episode "Gary's New Toy" by himself.
  • This episode was paired up with a rerun of "Knock Knock, Who's There?" during the original American airing.
  • Plankton has a fear of whales in this episode like he does in "One Coarse Meal" and "The Ghost of Plankton"; however, in "Jailbreak!," Plankton is not afraid of the whale cellmate.
    • Plankton also does not seem to know that Pearl is Mr. Krabs' daughter in this episode until she says that he is her father. In "The Algae's Always Greener" and "One Coarse Meal," however, he does know that Pearl is Mr. Krabs' daughter.
  • A clip from this episode was used for a COVID-19 promo from around April 2020.[10]
    • Another clip from this episode was used for a Patrick marathon in November 14, 2020 with a new episode of It's Pony.[11]
  • This episode and "Who R Zoo?" are the only season 12 episodes to not credit their supervising directors.
  • According to Ian Vazquez, this episode potentially implies that the Chum Bucket serves kids meals, as the Monster Maker packet features the restaurant's branding.[12]

Dub facts[]

  • In the Hebrew dub, Plankton has a very different voice than usual. This is because Tomer Shavit voiced Plankton in this episode instead of Zvika Schwartzberg.
