"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.



The episode opens with Karen leaving The Chum Bucket to go see her mother board. She tells Plankton she put up fliers for an intern, which leads to many people trying out, but leaving when they hear the minimum wage portion. Patrick tries out, (making clone of himself) and then Pearl joins. Pearl wants to leave because Plankton isn’t letting her do the “fun stuff”. Mr. Krabs tells Pearl she should just listen to her boss, no buts about it. She does, and Plankton said that if she helps him steal the secret formula, she can do the fun stuff. They sneak in, and find Spongebob “sleep cooking”. Spongebob gets thrown in the garbage can, waking up. He calls Mr. Krabs, and Mr. krabs comes running. Plankton and Pearl get caught, and Pearl and Mr. Krabs make a deal...Mr. Krabs has to triple her allowance. The end of the episode shows Karen back from seeing her mother board, and comes in to see the Patrick Clones working around the lab.

He might not have been afraid since the whale cellmate was working for him, or that he was able to overcome his fear of whales.
    • 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.
