Plankton tries to steal the formula, with Karen launching him into Mr. Krabs' brain but goes into SpongeBob's instead which Karen and Plankton didn't know SpongeBob was holding a cardboard of Mr. Krabs. Plankton goes into the optical system to see how to make Krabby Patties, but SpongeBob can't 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 Mr. Krabs, Plankton is already using SpongeBob's eardrums. SpongeBob can't hear Mr. Krabs so Mr. Krabs repeats himself, yells, and then uses a megaphone. Plankton doesn't want to hear that so goes to command central: the brain. When he goes inside, he's basically in SpongeBob's pineapple but spagetti-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. And then he acts like SpongeBob when Karen calls out to him, asking Plankton if he got the secret recipe of the Krabby Patty to which Plankton responds that getting the formula is stealing and Karen somehow brings him home but not before bumping into Patrick. Once accidentally sucking up info from Patrick, he becomes pink, chubby, stubby armed, one-toothed, and wearing the swimming trunks Patrick wears, and forgets the formula. Once Plankton is back at the Chum Bucket, Karen asks him what the formula is and Plankton is acting like an idiot, and he forgot the formula.
