"Salsa Imbecilicus" is a SpongeBob SquarePants episode from season 9. In this episode, Sandy and Karen must save the day, after everyone in town becomes as stupid as Patrick.



The episode starts with Plankton getting kicked out of the Krusty Krab in another failed attempt to steal the formula. Plankton wonders how Mr. Krabs keeps on stopping his plans to steal his formula if crabs' brains are smaller than the point of a pencil, but Sandy tells him Mr. Krabs would have be as dumb as Patrick to give up the formula. Plankton gets the idea of obtaining Patrick's DNA to make Mr. Krabs dumb, so he goes to Patrick while he is sleeping to obtain it.

After he obtains the DNA, Plankton starts making Salsa Imbecilicus at the Chum Bucket. However, he accidentally gets some on him and becomes dumb as a result. The stench of the sauce goes into a cloud, causing it to rain droplets of the sauce all over Bikini Bottom. Meanwhile, Sandy comes out of her treedome, only to see that everyone has become as dumb as Patrick.

"It's no use. Being smart takes work."

After noticing that everyone has lined up to go to the Chum Bucket, Sandy goes to Karen to ask what happened. After finding out, the two try to snap Plankton out of being dumb, but they fail. Eventually, they get the idea to start a university to make everyone normal again. Sandy and Karen get everyone to come to the university and they teach them successfully.

One Semester Later, everyone has become smart again except for Plankton, who has become the bully at the school. On Graduation Day, everyone is getting their diplomas. However, Mr. Krabs is still in the Home Ec room, perfecting the Krabby Patty. Plankton attempts to steal the patty from Mr. Krabs, but SpongeBob saves Mr. Krabs by giving him his diploma, which allows him to know not to give the formula to Plankton. The episode ends with Mr. Krabs throwing Plankton away onto Karen, who rolls into the distance.

  • The clown wig on Squidward's Easter Island house has the same color scheme of the rainbow that was first seen in "Suction Cup Symphony."
  • This episode was originally going to be called "Idiot Sauce," but the title was changed because it was deemed that it sounded "too mean."[3]
    • It may also have been because the Latin scientific term of "Salsa Imbecilicus" was more fitting, seeing as how Plankton created the sauce in a science lab.
    • Despite this, there are two episodes that had "idiot(s)" in the title: "Survival of the Idiots" and "Idiot Box." Possibly, the change comes from the difference in times.[4]
    • Plankton mentions both the actual episode title and the original title.
    • Other TV scheduling websites like TV Passport used the original title.
    • In the Arabic dub, this episode is called "صلصة الغباء" which translates to "Idiot Sauce."
  • Ironies:
    • Plankton could have just swabbed the saliva on the floor to get Patrick's DNA instead of going inside his mouth.
    • Despite being the one who created the idiot sauce, Plankton seems most affected by it as he is the only Bikini Bottomite who does not regain his intelligence.
  • A clip from this episode can be seen in Karen's memory bank in "Karen's Virus."
  • This episode marks the first for several things:
    • The first episode to play the third version of "Seaweed" since "Funny Pants" in season 4.
    • The first episode where Sandy and Karen work together.
    • The first appearance of the Bikini Bottom University.
    • The first time "The Rake Hornpipe" is heard since "Plankton's Regular."
    • The first episode to have Brian Morante as the storyboard artist. His work on the show was initially supposed to be freelance, but the crew liked his work so much that he was hired full-time.
  • This is the fifth and final episode to air for the July 2016 premiere week. It is also the lowest-viewed episode in the event.
  • According to Karen, Plankton has apparently boiled his underwear at least once sometime before this episode.
  • Karen breaks the fourth wall by playing a laugh track after Plankton gets humiliated.
  • This is the only season 9 episode where "Gator" plays.
  • Plankton says that a crab's brain is smaller than the point of a pencil. In reality, it is smaller than the size of a pea.
  • The clarinet song Squidward is seen playing at the graduation is also the song he performs in "SquidBob TentaclePants" and "No Hat for Pat."
  • The scene of Plankton gathering Patrick's DNA has become a notorious meme due to it being surprisingly vulgar.
  • When Plankton is revealed on Graduation Day to still be stupid, he has clearly gained intelligence from before starting school, as he is able to speak full sentences and supposedly bully people do what he wants. Otherwise, this is possibly an allegory to how most bullies are insecure and lack skill or intelligence themselves, therefore need to put others down to feel confident.
  • This was the second episode where Plankton uses another character's DNA for one of his plans. The first was "Plankton's Good Eye." In that episode, Plankton uses SpongeBob's DNA, and in this episode, he uses Patrick's.
  • This was the second episode where a "One-Way Chalkboard" can be seen at the end. The first was "New Student Starfish."
  • There is a reference to "New Student Starfish" when Sandy observes Mr. Krabs and Plankton through a chalkboard, which is what Mrs. Puff did for SpongeBob and Patrick in the aforementioned episode.
  • In the Croatian dub, the episode's name is "Umak za idiote" which translates to "Sauce for Idiots."
  • In the Russian dub, Plankton's scream after Patrick's tongue licks his butt was not dubbed.
    • Also, in this version, Karen's line when she asks Plankton if he is boiling underpants was changed to socks.
  • This episode has a similar ending to "Face Freeze!," as things do not completely go back to normal by the end of the episode.
    • The ending is also similar to its sister episode "Pineapple Invasion," since both end with Plankton walking into the sunset, though in this episode, Karen carries him. The sunset background from the aforementioned episode is reused.
  • In the Filipino dub, the scene where Patrick's tongue licks Plankton's butt was cut for inappropriate reasons.[citation needed]

Cultural references

  • The fish riding a bike on the sand in a circle is reminiscent of Curly of the Three Stooges running around on the floor.


  • When Plankton goes into Home Ec, his lips are out of sync for a moment.
  • When Mr. Krabs perfects the Krabby Patty recipe, the lettuce is supposed to go on top of the patty, but Mr. Krabs says it is correct.
  • When Karen carries Plankton away, he disappears and reappears for a few seconds.
