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 the meat of Plankton. This goes on for two nonstop weeks. Plankton then runs away and has nightmares about Pearl eating him and his cousins.
Plankton appears in the road, attempting suicide by being 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 is surprised but becomes angry when SpongeBob tells Plankton that it has been Mr. Krabs disguised as Pearl that's been scaring him. SpongeBob leaves while Plankton is left with a plan to get even with his rival.
Plankton decides to torment Mr. Krabs 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, but considering Mr. Krabs' change in attitude towards the clown after Plankton fled, it is implied that Mr. Krabs was not afraid of the clown at all (and his fear earlier was a façade to ensure the safety of the secret formula).

- During production, this episode was originally titled "Plankton Got Served."
- When Mr. Krabs is crying because of the clown, Plankton calls him "Scaredy Pants," which is the name of the Halloween episode from season 1.
- The episode's title card has the same font color as the title card for "The Inside Job."
- 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 a later episode, he interacts with another whale in jail and is not afraid of him.
- In "Married to Money," Plankton, disguised as Cashina, communicates with Pearl.
- In "Patnocchio," Plankton and Patnocchio go inside Pearl's stomach to retrieve a Krabby Patty. However, Plankton mentions that just being near a whale's mouth gives him the creeps.
- 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.

- 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.
- Plankton's bedroom in this episode completely differs from the bedroom he is shown with in "Bottle Burglars" and "Gary & Spot."
