"Plankton!" is a SpongeBob SquarePants episode from season one. In this episode, Plankton uses mind control to obtain the Krabby Patty formula.



At the Krusty Krab, Squidward sends SpongeBob an order for a Krabby Patty, and it ended up in his nose. After making the patty, it begins to "move" and makes its way towards the front door. Mr. Krabs pulls a tiny person out of the burger, whose none other than his arch-nemesis, Plankton, and sends him back to the Chum Bucket. Mr. Krabs explains that Plankton is his arch-competitor, and has been trying to steal the Krabby Patty's secret formula for years.

That night, after the Krusty Krab closes, Plankton tries to convince SpongeBob he and the fry cook are friends, and that as such SpongeBob should come to Plankton's birthday, as it is supposedly the following day. Plankton says that friends give each other things. Plankton asks SpongeBob what he thinks he'd like for a birthday present, and SpongeBob then guesses a booster seat. Plankton is very happy with that proposition, but refuses. Plankton tells SpongeBob that, for his birthday, he wants SpongeBob to give him a Krabby Patty. SpongeBob loudly and boldly refuses and runs back home, but Plankton promises that SpongeBob will "hand deliver it to (him) personally."

Later that night, Plankton enters SpongeBob's head through a pore and makes his way to SpongeBob's brain. He attaches a mind control device to the brain and bends SpongeBob to his will, forcing him to walk to the Krusty Krab, get a Krabby Patty, and bring it to the Chum Bucket's Laboratory. He brings it to an analyzer, which is designed to figure out the
Plankton! 149
ingredients of whatever is dropped into it. As Plankton gloats over his victory and begins to force SpongeBob to drop the Krabby Patty, SpongeBob laments his failure to save it, lovingly describing the Krabby Patty's ingredients and succulence (ironically revealing the Secret Formula). A hungry Plankton leaps out of SpongeBob's head and onto the Krabby Patty, but bounces off of it and falls into the analyzer, thus trapping him inside his computer screen. SpongeBob walks home with the Krabby Patty in hand, ignoring Plankton's angry demands for him to bring it back, his last plea being "I'll settle for some fries!" closing the episode.




In the audio commentary, Doug Lawrence reveals he won the voice of Plankton in an auditioning contest held at the beginning of production.

The audio commentary also reveals that there was originally a scene where Squidward was shown naked (possibly during the scene with his bedroom), but it was cut for obvious reasons.

  • This episode features audio commentary on The Complete 1st Season DVD. It's also the first episode of the series to use this feature.
  • This episode marks the first appearance of Plankton and his computer wife, Karen.
  • This is the first episode in the series to have a night-time setting.
  • This is the first episode to have live action within the SpongeBob SquarePants series.
  • This is the first appearance of SpongeBob's brain.
  • This is the first time where Sandy Cheeks does not appear in either of the segments.
  • This is the first episode to use the APM track "Hilo March."
  • In Plankton's laboratory, Karen is on the right wall from the doors, rather than the usual location straight ahead of the doors.
  • As Plankton says, "This is my lab.", it shows a real-life Labrador. This would also appear on the second SpongeBob level in the console version of the video game Nicktoons Unite!
  • This is the last episode of the series where the "a"s in the crew member's names were filled in. All episodes starting with "Naughty Nautical Neighbors" have the "a"s unfilled.
  • This is one of the few season 1 episodes where the Krabby Patty buns' sesame seeds are colored white. In most season 1 and early season 2 episodes, they are colored black.
  • According to the closed-captions, when Plankton speaks to Squidward through SpongeBob, he says Squidward's creations are "worth less than a protozoan's waist." This might be an error, as Plankton could have meant, "protozoan's waste." Since protozoans are extremely tiny creatures, and thus their waists would be small as well, it's possible that the captions were accurate.
  • Plankton has a record in which to dramatize his evil schemes. The record is Verve by Jack Shaindlin, and its B-side is "The Alphabet Song" sung by Peter Gosling.
  • According to Karen, Plankton is 1% evil, 99% hot gas.
  • When SpongeBob is first making Krabby Patties, he throws one up in the air that disappears, probably because he had already put one in his head.
  • In Germany, the title card doesn't change.
    • This is because the word "Plankton" in German is spelled out the same way as English.
  • The scene when Plankton says "Come back here, you swine!" is sometimes cut because the word swine is offensive in some countries.[citation needed]
  • In the audio commentary for the episode, Bill Fagerbakke comments that there has never been a Patrick episode with an exclamation mark after the title. Years after this commentary was recorded, two were released in season 9. They are "Patrick-Man!," and "Patrick! The Game."
  • A short snippet of SpongeBob's laugh in this episode is one of the unused sound files in Revenge of the Flying Dutchman.
  • This is the first episode to have German dub version of this episode with the exact same name as the English version.
  • The part where SpongeBob says "Get out of my brain!" has become an internet meme.
  • In The Big Bang Theory episode "The Long Distance Dissonance," Sheldon Cooper is seen watching this episode, specifically the scene where SpongeBob breaks through the wall in his house while being controlled by Plankton.

Cultural references

  • The scene where SpongeBob turned his head 180 degrees may have been a reference to the 1973 film The Exorcist.
  • The Labrador/laboratory gag was used before in the Cartoon Network series Dexter's Laboratory.
  • A scene from Melon Felons appears on the big TV in the Chum Bucket, when it shows Plankton's "lab" (dog).
  • Plankton plays the nursery rhyme "This Little Piggy" on SpongeBob while trying to force him to drop the Krabby Patty.
  • When Plankton says "You weak-minded fool!," this is a reference to the 1983 film Star Wars: Return of the Jedi.


  • When SpongeBob is forced to steal a Krabby Patty and crashes through the sides of the Krusty Krab, the lights are on, meaning someone (probably Mr. Krabs) was in the building at the time and should have come out to see the damage, although the character never did.
  • On the television schedule, the episode is listed as "Plankton" without the exclamation point at the end of title.
  • SpongeBob is not seen wearing his Krusty Krab employee hat at the Krusty Krab in this episode.
  • When Mr. Krabs first appears on this episode, his first lines are "Avast ye patty pirate! This is no ghost. This is... Plankton!" When he says "This is no ghost," his mouth is visible; however, his lips do not move.
  • The closed-captioning makes a spelling mistake for this episode. It spells "Krabby Patty" as "Crabby Patty."
  • At night when SpongeBob is walking home, he moves his head to his left to right and the Krusty Krab across the Chum Bucket is missing.
  • When SpongeBob drops the golden spatula it is right next to him. When he walks away from Plankton, it is gone.
  • The brain-control device says "Total Control," however, all Plankton controls is SpongeBob's movements and his words.

Black tie

  • When SpongeBob first walks toward his pants, his tie is red. When SpongeBob's pants are pulled across his face, his tie is black. Right after his pants are back in their normal spot on the hanger, his tie is red again.
  • When SpongeBob walks into Squidward's bedroom, it is on the first floor. However, in all other episodes, it is on the second floor.
    • Considering the fact that this is the first time Squidward's bedroom appears, it's possible Squidward moved upstairs.
  • When being forced into the Chum Bucket lab and screaming, SpongeBob's mouth doesn't move.
  • Even though Plankton continues to try to find out the formula after this episode, SpongeBob revealed the entire formula in this episode with Plankton in his head. It is possible Mr. Krabs might have fired him for doing that, or that Plankton thought SpongeBob was lying or he was too distracted while SpongeBob was describing it.
    • It is also possible that the secret is the exact ingredients proportions or the exact method to cook every ingredient.
  • The words "Total Control" disappear and reappear on the controller Plankton uses.
  • When SpongeBob squirts mustard into his eyes, it doesn't burn them.
  • How could SpongeBob not hear Plankton's record player next to his bed?
