"The Ballad of Filthy Muck" is a SpongeBob SquarePants episode from season 12. In this episode, Patrick takes his grime to a new extreme, playing around in so much trash that he becomes unrecognizable.



In the beginning of the episode, Patrick wakes up and gets out of his rock so he can walk to the Krusty Krab. Everyone in the restaurant then runs out due to Patrick's hideous smells, but when SpongeBob smells his stench, he is amazed at just how smelly he is. After SpongeBob decides to smell Patrick again, Mr. Krabs smells an awful stench and investigates what it is. He finds out that the stench is coming from Patrick, so he kicks him out of the restaurant. This makes Patrick angry and wants to revolt for his stink-dependence.

Filthy Muck.

Patrick starts messing around in grimy places of the city, but when he starts messing around in the Dump, he eventually becomes so filthy he is unrecognizable. Patrick starts going around town in this filthy form, causing him to get listed in the newspaper as Filthy Muck. SpongeBob finds out about this news and tries to look for him, eventually finding him at the Dump. Since Filthy Muck has a force-field of stink, SpongeBob puts on a filthy mustache on himself to prevent the smell, but this leads to him getting into Filthy Muck's game and starts to go around in the grime as well.

Another news article comes out about how Filthy Muck now has a partner. SpongeBob and Filthy Muck start going all over town, causing people to run away due to their smells, except for Old Man Jenkins, as he cannot smell. Eventually, the citizens have had enough of this, so they confront the two gross creatures and riot against them. SpongeBob cleans himself so they do not riot against him, but he tries to tell the citizens that Filthy Muck is his friend and he does not want him to get hurt. However, the citizens still try to run them out of town.

Eventually, SpongeBob tries to clean Filthy Muck, and tells everyone if they work to clean him, he will turn normal again. Everyone does so, but Filthy Muck completely disappears after getting cleaned. It turns out Patrick had gone to take a bath, after he realized he would be forbidden from the Krusty Krab. SpongeBob realizes it was just muck the mob cleaned up. Old Man Jenkins then freaks out after seeing Patrick letting go of his towel, exposing his posterior to everyone. The crowd laughs while on a hill, the Filthy Muck reforms and Rube takes a picture as the episode ends.

  • The title card background is similar to "Ghoul Fools," except it is green.
  • The French narrator breaks the fourth wall when he smells the stink, despite him being the narrator.
  • "Welcome to the Chum Bucket" and "Eat at the Krusty Krab" ads can be seen on the newspaper.
  • The only thing Filthy Muck says orally is "Yummy!"; for the rest of the episode, he is mute, aside from his giggling and mumbling. In the scenes where SpongeBob is with Filthy Muck, SpongeBob does all the talking.
  • Foreshadowing: Whenever Filthy Muck is around SpongeBob, he never says a single word. This is a clue that Filthy Muck is not Patrick.
  • This is the first episode in the show's history that had less than one million U.S. viewers.
  • This is the fourth episode in the series where the Chum Bucket appears without Plankton. The first was "Slide Whistle Stooges," the second was "No Hat for Pat," and the third was "Don't Wake Patrick."
    • In most episodes where Plankton is absent, the Chum Bucket is missing.
  • This episode and its sister, "The Nitwitting," are both Patrick-themed.

Episode references

  • This is the second episode where SpongeBob mistakes the angry mob by asking them what they're having but the mob telling him their true colors, in this case, "Hello, are we having a lu'au?" The first time was "Sleepy Time," when he asks, "What are you all doing in your pajamas? Are we having a slumber party?"
  • An ice cream sign at Glove World! says, "Glove Flavor," a hint of the candy glove flavor that SpongeBob ate in "Rock Bottom" at the location of same name which he confirmed he hates that flavor in said episode.

Cultural references

  • The mini crab bank references the mini cat coin bank.
  • The picture of Filthy Muck in the newspapers is a reference to the Patterson–Gimlin film, a famous short film that featured the mythical Bigfoot.
  • The "inclamation of stink-adendence" is a reference to the Declaration of Independence.
  • The big-nosed fish who shows up throughout the episode is a caricature of Jimmy Durante, a celebrity who had an unusually huge nose. He referred to it as his "schnozzola," which is also referenced in the episode.


  • When Patrick gets kicked out of the Krusty Krab, the Chum Bucket across the street is missing.
    • In the same scene, the Krusty Krab doors are not broken, nor is the sign melted.
  • In one scene, SpongeBob's eyelashes on his right eye disappear for one or two frames.
  • In the European Spanish dub, Bikini Bottom (Fondo de Bikini) is accidentally called by its original name when the narrator says "Parque de Bikini Bottom," when it should be "Parque de Fondo de Bikini" (Bikini Bottom Park).
