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



The episode begins 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 small, 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's 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 to rain down 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.

After seeing 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.


Vincent Waller confirmed this episode on Twitter on May 17, 2016[1] and, at the time, it was under a working title called "Idiot Sauce."[2]

  • 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]
    • Despite this, there are two episodes that had "idiot" in 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.
  • Irony: Plankton could have just swabbed the saliva on the floor to get Patrick's DNA instead of going inside his mouth.
  • This is the first episode to play The track "Seaweed Version 3" since " Funny Pants" in season 4.
  • 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.
  • Plankton says that a crab's brain is smaller than the point of a pencil. Actually, it is about 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."
  • This was the first episode where Sandy and Karen work together.
  • This was the first appearance of the Bikini Bottom University.
  • The scene where Plankton gets licked by Patrick's tongue while collecting his cheek DNA has become a notorious meme on the Internet, alluding to memes that include "thicc" statements and "I watch SpongeBob for the plot" comments.
  • Irony: Despite being the one who created the idiot sauce, Plankton seems most affected by it as he's the only Bikini Bottomite who doesn't regain his intelligence.
  • When Plankton is revealed on Graduation Day to still be stupid, he has clearly gained intelligence from before starting school as he's 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 episode marks the first time "The Rake Hornpipe" is heard since "Plankton's Regular."
  • This was the second episode where Plankton uses another character's DNA for one of his plans. The first is "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 is "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 "Gravy for imbeciles."
  • In the Russian dub, Plankton screams after Patrick's tongue licks his butt wasn't 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 this time, Karen carries him this time. The sunset background from the aforementioned episode is reused.

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.

Running gags

  • Karen playing a laugh track after each humiliation.
  • Patrick riding a skateboard upside down.
