At the Bikini Bottom Mall, SpongeBob and Patrick try on shirts that read "Best Friend" with arrows pointing to their sides. When they stand besides one another, their shirts point at each other. However, they discover that when either of them faces a different direction, the arrow points elsewhere, thus "sending out the wrong signals." In seeking out new friendship clothes, the pair finds a group of citizens donning traditional military uniforms. Mistaking the uniforms for "matching outfits", they are taught that the fish are participating in a reenactment of the Battle of Bikini Bottom. When SpongeBob reveals that he is unaware of the historical event, Patrick erroneously recounts the conflict between two supposed factions: the clean, obsessed with personal hygiene, and the dirty, unconcerned with such matters.
SpongeBob, upon realizing that Patrick sympathizes with the filthy side, expresses his disgust. The two begin to argue, to the annoyance of the fish trying to recreate the actual battle. SpongeBob and Patrick appropriate uniforms and engage in their own reenactment of Patrick's imagined war, driving the fish away. SpongeBob and Patrick commence their battle, exchanging a series of volleys in which SpongeBob attempts to bolster Patrick's cleanliness and Patrick attempts to defile SpongeBob's sanitary nature. This culminates in a standoff in which SpongeBob consumes a soap bar and prepares to pelt Patrick with soap bubbles shot through his pores. Patrick, in retaliation, picks up a dumpster and hurls it at SpongeBob as he starts his assault. The bubbles scour Patrick off his feet just as the dumpster lands on SpongeBob.
In the aftermath, Patrick is made squeaky clean and SpongeBob is covered in filth. As they reflect upon the copious amounts of cleaning/soiling that it will take to return them to their respective states of tidiness/mess, they realize that this only means that they are provided an opportunity to indulge in what they each love to do. As they reconcile, the fish return, intolerant of a stalemate. SpongeBob gives a sermon on the duality of their conflict, and makes a case for neutrality on the basis that one side cannot exist without another to provide reference to each other. The fish dismiss SpongeBob's message, forgoing the frilliness of reconciliation for "more manly" pastimes. Satisfied, SpongeBob and Patrick walk into the sunset.

- Critic Paul Mavis of the DVD Talk in a review of SpongeBob's Pest of the West, praised the episode for its "memorable" opening scene and SpongeBob's line, "Patrick's digging for gold!"
- The episode title is similar to that of the video games Battle for Bikini Bottom and Battle for Bikini Bottom - Rehydrated.
- In this episode, Patrick says he has never washed his hands. However, in the episode "Something Smells," Patrick is seen washing his hands in the movie theater bathroom.
- The close-up of SpongeBob's teeth was featured in the SpongeBob SquarePants online game Cavity Crisis.
- Contrary to this episode, Patrick has brushed his teeth before in previous episodes, as seen in "Dumped" and "Rise and Shine."
- SpongeBob says that Patrick does not have a nose, however, he is shown to have one in "Wet Painters" and "That's No Lady."
- Patrick has been clean in other episodes (such as "Shanghaied") and SpongeBob is dirty in other episodes like "Gary Takes a Bath."
- In this episode, it is shown that Patrick's eyes are navy-blue, although in "Wormy," his eyes are green, and in "Oral Report," they are jade.
- This is the second episode to have a title card background on a pirate map. The first is "Arrgh!"
- This is the second episode where SpongeBob and Patrick are against each other. The first is "The Fry Cook Games."
- If counting this episode segment and its sister in one episode instead of separate segments, the previous and next episodes are both specials in-between this episode.
- The Battle of Bikini Bottom could be a parody of the Revolutionary War, judging from the military uniforms. The red-coated soldiers have British accents in the flashback, and the blue coats have American accents. This is a reversal of the actual war, in which the Patriots wore blue, and the British wore red.
- Harold was shown to be on the clean side in one scene then later he is shown on the dirty side.
- In the scene with the Bikini Bottomites firing soap and trash with their cannons, some of the trash lands in the air, so it appears floating.
- As Bill says, "That's not what happened," one of Patrick's eyebrows are missing until he turns his head.
- In one scene, SpongeBob's eyelashes disappear for a split second.
- After SpongeBob pedicures Patrick, the chair and bucket of water in the background disappear.
- SpongeBob paints Patrick's toenails red. After Patrick turns and says to SpongeBob "You sick little monster, face my morning breath!," the red nail polish is gone for the rest of the episode.
- If one listens closely as Patrick loses his armpit hair, he can be heard coughing and choking even though his mouth does not move.
- When SpongeBob is running in Jellyfish Fields and saying, "Ahhh, booger!," one of his white teeth turns yellow for a split-second.
- On the DVD releases, if one plays it frame by frame, during the scene when Mr. Krabs runs into the kitchen looking for gold, they can see the door actually opens by itself before Mr. Krabs pushes it.
- When Patrick was thrown out of the Krusty Krab, the Chum Bucket located across the street doesn't appear.
- When Patrick is holding the dumpster, his teeth are miscolored for one frame.
