"The Sewers of Bikini Bottom" is a SpongeBob SquarePants episode from season 9. In this episode, after accidentally flushing Mr. Krabs' safe, SpongeBob and Squidward must go into the sewers to find it. Meanwhile, Mr. Krabs visits the new Krusty Krab Stadium, which is having plumbing issues.



The episode starts at the Krusty Krab, where SpongeBob and Squidward are working, and Mr. Krabs comes to tell them that Bikini Bottom's newest stadium will be named after the Krusty Krab. He then tells them that employees have to stay at the restaurant to continue working. Mr. Krabs puts Squidward in charge of the Krusty Krab while he is gone and he leaves.

SpongeBob wakes up a sleeping Squidward, asking for jobs to do. Squidward tries to find some work, but notices SpongeBob has done most of them already. Squidward then has SpongeBob clean some more, but he does all of the work in seconds. Squidward, after running out of ideas, tasks SpongeBob to flush things down the toilet, so SpongeBob goes into the bathroom to do so. Squidward realizes his mistake and tries to stop SpongeBob. Before, SpongeBob flushes a mop down the toilet and Squidward finds it exciting. He and SpongeBob then flush various objects down the toilet, but are horrified after accidentally flushing down Mr. Krabs' safe, which contains the Krabby Patty secret formula. SpongeBob decides to flush himself to go and get it and Squidward, realizing he needs SpongeBob to cook the Krabby Patties for the customers, follows SpongeBob down the toilet.

At the Krusty Krab Stadium, Mr. Krabs is talking to Crupski and Charlton Hawkfish about Mr. Krabs buying the stadium. Customers outside are complaining about the plumbing and Charlton is angered to not only see that the pipes have a reducer in it, but are also made out of cardboard. Charlton worries that the pipes will not hold, but Crupski says it is a way to save money, much to the delight of Mr. Krabs. Meanwhile, SpongeBob and Squidward make it to the sewers, where they begin their search for the safe. They manage to spot it where it gets stuck in the pipes. As Squidward tries to reach for it, the safe gets unstuck and floats away. Squidward fails to grab it again and a couple of lampreys bite at his hands. SpongeBob helps get the lampreys off and spots the safe floating in the distance. SpongeBob and Squidward go after it once more and, suddenly, a large sewer snake emerges from the water.

Back at the stadium, Charlton warns Mr. Krabs and Crupski that it is time for the "halftime wave," where every toilet flushes at once. Mr. Krabs ignores this and continues to watch the game. Back in the sewers, SpongeBob and Squidward are running away from the sewer snake, but end up running inside of it instead. Squidward, afraid, starts to run around frantically and SpongeBob spots the safe nearby, trying to inform Squidward of it. Eventually, the sewer snake vomits up SpongeBob, Squidward, and the safe, which lands on Squidward's head. Meanwhile, everyone at the Krusty Krab Stadium starts to use the restrooms, where Charlton warns that the pipes are going to burst. The pipes then proceed to do so and a large amount of water pours inside of the stadium. Charlton dives underwater and activates his fail safe, which is a giant plunger that plunges away all of the water. Charlton blames Mr. Krabs and Crupski's cheapness for causing the problems and the sewer snake rises above in the stadium.

However, Charlton uses his nose to pop the sewer snake and it goes back into the sewers. SpongeBob and Squidward end up back in the Krusty Krab in the safe, where they are ready to get back to work. However, the customers all run out screaming, as the episode ends.

  • In the opening credits, Lynne Naylor is misspelled as Lynn Naylor.[5]
  • Squidward comments that he flushed SpongeBob down the toilet. However, SpongeBob flushed himself down the toilet.
  • The Krusty Krab cash register is one of the things that Squidward and SpongeBob threw down the toilet and flushed. However, the Krusty Krab cash register still appears at Squidward's workstation in some later scenes.
  • When SpongeBob and Squidward are in the bathroom, there is only one toilet, while there are usually three.
  • When Charlton says there is only five minutes until halftime, the TV clearly says there is 10:42 left. The score and time on the scoreboard and TV are also inconsistent throughout the entire episode.
  • When the stadium first gets flooded, one can clearly see the grandstands are full of people when all of them left to use the bathroom. This error is fixed in the next shot when the football players are running away from the flooding.

Misspelled SpongeBob's shoe.

  • In the end credits, "SpongeBob's shoe" is misspelled as "SpongBob's shoe."
  • In the last shot, where everyone is fleeing from the Krusty Krab, neither SpongeBob nor Squidward are visible inside. The Galley Grub and Order Here signs are also missing throughout the entire episode.
  • When Charlton, Crupski, and Mr. Krabs watch the fish talk through the window, Crupski's eyebrows are smaller and thinner than usual.
  • When Charlton first unrolls the map, there are no markings or writing anywhere on it. Later on, when Mr. Krabs is talking about the Bikini Bottomites, the map is only a grid with no drawings on it.
  • The flags on the wall near the TVs in the Krusty Krab Stadium continuously change size and distance from each other.
  • When Charlton pulls himself out of the hole the flooding caused, there are more people shown on the field than there were in the far shot of the field.
    • Also, when Charlton is talking, the fish in the grandstands have no pupils in their eyeballs.
  • When Charlton confronts Crupski and Mr. Krabs on the field, there are suddenly no fish in the grandstands. This error occurs for the remainder of the episode.
  • On both shots of the outside of the Krusty Krab, there is a fish on the inside whose pupils are facing the ceiling and the ground. There are also more people who appear in the Krusty Krab than there are on the outside shot of it.
