Mr. Krabs is sleeping in his money bath, when he smells something burning. SpongeBob then tells Mr. Krabs that it smells like Plankton with his new explosives. Plankton then blows up the Krusty Krab, while his machine captures SpongeBob and Mr. Krabs. Then, Pearl comes to the kitchen and, being afraid of whales, Plankton runs back to the Chum Bucket in panic. Mr. Krabs asks Pearl for one of her dresses so he could disguise as her to scare Plankton.
Plankton tells Karen about his fear of whales and finding Pearl in the lab. She tells him there are no whales in the Chum Bucket. Then, Mr. Krabs, disguised as Pearl, scares Plankton. He enters in the Chum Bucket and Mr. Krabs appears saying that he wants to eat Plankton. This goes on for two nonstop weeks. Plankton then runs away and has a nightmare about a demonic Pearl eating him and his cousins.
Plankton appears in the road, attempting suicide to get run over. SpongeBob becomes concerned about this and tries to tell Krabs to stop harassing Plankton, but he doesn't listen. Since Krabs won't listen to reason, SpongeBob then tells Plankton about Mr. Krabs' worst fear. Plankton suddenly stops his suicide attempt, and is surprised but becomes angry when SpongeBob tells him that it has been Mr. Krabs disguised as Pearl that's been scaring him the entire time. SpongeBob leaves while Plankton is left with a plan to get even with his rival.
Plankton decides to get revenge on Mr. Krabs by tormenting him with a mime. Later, SpongeBob scares Plankton away with holographic whales to keep him from getting the formula. SpongeBob then releases Mr. Krabs and the mime continues to torment him as the episode ends.

- "One Coarse Meal" was ranked #99 during the SpongeBob's Top 100 event in the UK and Ireland from June 4-8, 2012.
- During production, this episode was originally titled "Plankton Got Served."
- The title card is similar to that of "Nature Pants," "Karate Island," "Night Light," and "Banned in Bikini Bottom," except it’s light purple and the edges are ominous.
- The Wacky Bucks would later appear in the video game Battle for Bikini Bottom - Rehydrated.
- When Mr. Krabs is crying because of the mime, Plankton calls him "Scaredy Pants," which is the name of the Halloween episode of the same name.
- Plankton is scared of whales in this episode. Although in other episodes, he has encountered Pearl without panicking. Also, in one of the episodes, "The Algae's Always Greener," Plankton says "look at his daughter, she's as big as a whale."
- In "Mermaid Man & Barnacle Boy VI: The Motion Picture," Plankton does not show his fear.
- "Coarse" is another term for "rough." Therefore, the title of the episode means "One rough meal." However, it is clearly a play on words of a one course meal.
- This episode shows that Plankton is a skilled bubble blower, as he was able to make a bubble shield strong enough to withstand the peas that SpongeBob was spitting at the speed of a bullet.
- It is revealed that Plankton is afraid of whales and that Mr. Krabs has a secret fear of mimes.
- When Plankton calls SpongeBob "cheesehead," it is a reference to "What Ever Happened to SpongeBob?" in which he goes by that alias as mayor of New Kelp City.
- The transmutator was a scanner in "Plankton!"
- Just before Pearl comes into the kitchen, Plankton wonders what the smell is. SpongeBob says it smells like blubber, and Plankton panics. In "Spongicus," he says one of the ingredients to his chum is whale blubber, so it is unusual that he would not know what blubber smells like.
- It is revealed that Mr. Krabs can do a perfect Pearl impression; he can imitate her voice perfectly.
- One of Plankton's ancestors resembles Clem.
- In the Croatian dub, the episode name is "Jedna mala izmišljotina" or "One little fabrication."
- This is the first episode where "Another Best Day Ever" plays.
- When the camera zooms out on Plankton, a box appears over his face.
- When SpongeBob goes into Mr. Krabs' office after he erases a drawing of Plankton, the pencil and paper he used is gone.
- When SpongeBob is letting Plankton know about the whales outside the Krusty Krab, his facial animation resets for a brief moment.
