"The Krusty Sponge" is a SpongeBob SquarePants episode from season five. In this episode, Mr. Krabs makes the Krusty Krab SpongeBob-themed after a critic reviews SpongeBob's work.



One day at the Krusty Krab, Squidward noticed that SpongeBob was not filling orders, so he goes to investigate with Mr. Krabs. He discovers that SpongeBob has something Mr. Krabs describes as the "1,000 yard stare" and they both discover a Calendar in his hat that has the Date of that day circled and that a food critic was coming for a visit.

Mr. Krabs and SpongeBob are both in shock as Gene Scallop (food critic) walks in the doors. As he is having his first glimpse of the restaurant, Squidward rudely asked if he was coming in or out, and drove him away with other rude comments. Mr. Krabs stops him & serves him a Krabby Patty but he takes a bite and leaves the restaurant in a hurry. Mr. Krabs loses hope.

SpongeBob, Mr. Krabs, and Squidward watched as the critic gave his review on the Krusty Krab, only to soil it. He says that the Krusty Krab "smelt like the rear-end of a goat. Baaaaa! Phhhpt!" as the customers hear the review they begin to leave in displeasure, but Gene says that the Krusty Krab is a big success because of the Krabby Patty and SpongeBob was no square when it came to cooking, ending with a good review. The customers come back pleased and prepared to eat.


The next day, SpongeBob goes to work and sees that there is a new sign at the Krusty Krab, reading The Krusty Sponge, he also sees a long line, and Squidward in a SpongeBob costume as the restaurant's mascot. A boy named Tyler asks Squidward in his SpongeBob costume for his autograph and Squidward accidentally slaps him disappointing Mr. Krabs. SpongeBob finds out that his new job is to run a train outside the Krusty Krab, which Mr. Krabs charged customers to ride. When SpongeBob is out of energy from driving he stops pedaling but his passengers unfortunately do not care in the slightest at how obviously exhausted he is and demand on threat of riot that he keep pedaling. SpongeBob manages to slip away and discovers Mr. Krabs had gotten all kinds of new products, customized to look like SpongeBob.

He also discovers that the new Spongy Patties (actually tainted meat), Krabby Patties that look like SpongeBob, were making people sick by turning them yellow with spots like SpongeBob and giving them terrible stomach pains. Mr. Krabs comes out and thinks he is invaded by zombies but SpongeBob explains they are actually his customers who ate the Spongy Patties. Mr. Krabs is ordered to court by one of the customers who is actually an FBI agent. Mr. Krabs is shocked and realizes what he has done. In court, Mr. Krabs feels guilty and decides to accept the charges and turn himself in. Just as Mr. Krabs is about to go to prison, he makes a deal with the Judge, who was a huge SpongeBob fan. The deal is that Squidward has to drive the Judge around on the SpongeBob Train for the rest of the day if Mr. Krabs does not want go to prison. Squidward depressingly drives the Judge around the SpongeBob train and the Krusty Krab returns back to normal.

  • This episode is paired up with "Squid Wood" on


  • This episode aired in Germany on June 28, 2007, before it aired in the USA.
  • This is one of two episodes were bikini bottomites actually DO become zombies. The other one is "Krabby Patty Creature Feature."
  • The calendar in SpongeBob's Krusty Krab Employee Hat has a lion on it. This is the Zodiac sign Leo, which indicates it was probably between July and August 23.
  • This is one of few episodes to reveal what time the Krusty Krab closes.
  • When it's revealed that SpongeBob is petrified because he's worried about an important food critic's visit, Squidward says, "Only a complete moron would worry about what some critic has to say." In other episodes, Squidward himself is worried about what other critics have to say about his art. This shows that Squidward is picky with what critics he does worry about and what ones he doesn't worry about.
  • Gene Scallop has a similar appearance to the DJ in the Thug Tug from The SpongeBob SquarePants Movie.
The Krusty Sponge Gene Shallots

Gene Shallots fact.


Mr. Krabs having a back issue.

  • When Mr. Krabs escorts the SpongeBob boxes into his kitchen, he is seen spazzing, as to indicate that Mr. Krabs either pulled a muscle or cracked his back. This was first seen and mentioned in "The Lost Mattress."
  • The changes Mr. Krabs made were:
  • The combination of spots and yellow skin is a reference to chicken pox and yellow fever which both show symptoms on a person's skin.
  • A customer is seen holding a spoon and a fork at the Krusty Krab. Even though, it is shown that there are no meals that require silverware at the Krusty Krab.
  • Bikini Bottomites thought they were zombies before in the episode "Once Bitten."
  • In "Born Again Krabs," Mr. Krabs gets food poisoning himself by eating an old, rotten Patty.
  • Some fish from "Krabs vs. Plankton" are seen in the court. That might be because the producers might have reused the court backgrounds.
  • One could question how legal it would be for Mr. Krabs to bribe the judge with Squidward's services, yet Mr. Krabs is not shown to be in trouble with the law in future episodes.
  • Mr. Krabs' greed is really shown as he would sell rotten patties and double the price for profit while disregarding the health violations. Of course, like in most episodes, Mr. Krabs greed makes him act stupid to realize the health violations.
  • For Gene to have food poison, implies he made a second (off-screen) visit to the Krusty Krab.
  • In Bahasa Malaysia version, the prison's word is replaced with river.
  • This episode premiered on the same day Behold, No Cavities! was published.

Cultural references

  • The fame and popularity that SpongeBob SquarePants has in this episode is a shout-out to the massive amount of popularity that he has in the real world.
  • Though not explicitly implied, the man in the beginning who is of low intelligence and obese is similar to the character Fred Fredburger from The Grim Adventures of Billy & Mandy, of whom writer/storyboard artist C.H. Greenblatt had voiced.
  • The thousand-yard stare is a real condition wherein a person suffering from posttraumatic stress disorder stares into deep space after continuous exposure to traumatic events. This concept was popularized after being commonly found in returning soldiers from the Western Front during World War II.
  • Gene Scallop is a spoof of his real-life counterpart Gene Shalit.
  • The Krusty Sponge's monument of a giant SpongeBob holding a giant Krabby Patty is a spoof of the Big Boy Restaurants chain.
  • The judge's last name is "Whopper," which is a parody of the signature hamburger sold by Burger King. This makes sense as Burger King used to put out SpongeBob SquarePants toys whenever there was a big SpongeBob event happening and often promoted SpongeBob in any way.
    • "Whopper" is also a fishing term for a very large fish, especially one that got away.
    • The judge's name may also be a reference to Judge Joseph A. Wapner, a retired former American judge and former TV judge in the courtroom reality show The People's Court. The show's theme plays during the episode after the cut to the courtroom.


  • In the beginning, Dale and Jimmy Gus are behind the orange fish customer, but in the next scene, Nat gets his order taken. 
  • Squidward's arms cannot move when he is trying to give the child an autograph while he is in the SpongeBob costume, but they can when the judge rides the SpongeBob train.
  • When the train is first shown in the second to last car, Miss Rechid is gray, but in the next shot she is blue.
  • When Squidward is cooking Krabby Patties with his nose, the grill is on the opposite side of the kitchen. This error also happened in "Your Shoes Untied" Although, earlier in the episode, the grill is in its original area.
  • Even though the patties make the fish yellow with green spots, when Jimmy Gus is shown in the stands he is normal with yellow spots.
  • At the end, with Squidward driving the Judge on the train, and SpongeBob behind the grill, it is not mentioned if there is still a cashier at the Krusty Krab.
  • When a female fish says "That's the worst SpongeBob costume I've ever seen," she has a man's voice.
  • In the courtroom scene, Gene Scallop says: "We, the jury, find the defendant, Eugene H. Krabs, guilty of all charges," but the captions say: "We, the jury, find the defendant, Eugene A. Krabs, guilty of all charges."
  • Squidward in the SpongeBob costume was seen Near a "As Seen On TV" Sign, but when the kid comes to ask for his autograph, its gone
