"The Inside Job" is a SpongeBob SquarePants episode from season seven. In this episode, Plankton explores SpongeBob's brain.



Plankton tries to steal the Krabby Patty secret formula, with Karen launching him into Mr. Krabs' brain, but ends up going into SpongeBob's brain instead, which Karen and Plankton did not know SpongeBob was holding a cardboard cutout of Mr. Krabs until he moved it away.

Plankton goes into the optical system to see how to make Krabby Patties, but SpongeBob cannot see and uses inedible things to make it. Plankton sees that as useless, so he goes to the audio system. Before that, SpongeBob thinks he forgot to make the Krabby Patty, so he asks Mr. Krabs to tell him the secret recipe again, but by the time he gets in front of

him, Plankton is already using SpongeBob's eardrums. SpongeBob cannot hear Mr. Krabs, so the latter repeats himself by yelling, then by using a megaphone.

Plankton does not want to hear that, so goes to the command central: the brain. When he goes inside, he is basically in SpongeBob's pineapple but spaghetti-ish and pinkish, so he goes into the library. He looks at SpongeBob's secrets and finds that the formula is in the heart. He slides the vertebrae down there and when he sucks information from SpongeBob's heart, he becomes yellow with lime spots (holes), grows two buck teeth and eight fingers, and somehow, brown pants, black shoes, a red tie, and a white shirt are on him.

Plankton then acts like SpongeBob when Karen calls out to him, asking him if he got the Krabby Patty recipe yet, to which Plankton responds that getting the formula is stealing. Karen somehow brings him home, but not before bumping into Patrick.

Once accidentally sucking up info from Patrick, Plankton becomes pink, chubby, stubby-armed, one-toothed, grows the swim trunks Patrick wears, and forgets the formula. Once Plankton is back at the Chum Bucket, Karen asks him what the formula is. Plankton acts like an idiot since he forgot the formula after turning into Patrick.
