The Krusty Krab hasn't had a customer in 36 days, and is shown to be filled with cobwebs and even a skeleton. Dave crawls in, claiming that he hasn't had any food or a drink in 3 days. SpongeBob immediately gives him a meal, but he refuses, saying that there's no atmosphere in the Krusty Krab, and resumes his search for food and a theme. Mr. Krabs overhears a conversation between Tom and Fred about a talking dog at the Shell Shack, and realizes that he needs a gimmick to attract customers. SpongeBob tries to give him an idea, but is cut off by Mr. Krabs, who decides to bury himself alive in front of a crowd that leaves him when news of the now singing dog reaches them.
SpongeBob, in an angelic costume after being ignored by Mr. Krabs for a while, gives him an idea: "Pretty Patties", which are Krabby Patties, painted in a variety of colors. Squidward and Mr. Krabs laugh at him, and say that it's a terrible idea. They even create other ideas such as "sequined milkshakes" and "bow-tied french fries" to mock SpongeBob, which angers him. He leaves the Krusty Krab and sets up a stand in front of his house selling Pretty Patties, with Patrick, which is initially unsuccessful. He tries to give Harold a Pretty Patty, who laughs at that. SpongeBob is about to give up, when Harold sees a purple patty, his favorite color, and proclaims Pretty Patties to be the best idea ever. Following this, sales skyrocket.
Mr. Krabs sees this on the news and decides to take a look. SpongeBob is now serving the 46,853rd customer and has a large sum of money, which he and Patrick are giving away to the customers. Mr. Krabs says that he's never had that many customers in such a small amount of time, and gives SpongeBob the Krusty Krab in exchange for the "Pretty Patties" stand (as SpongeBob missed the Krusty Krab).
The next day, as Mr. Krabs is ready to make money, the customers all show to explain that the Pretty Patties had the side effect of turning them into their colors, and form an angry mob which begins chasing Mr. Krabs. He begs SpongeBob to let him into the Krusty Krab (since he gave the Krusty Krab's key to SpongeBob), but he is too distracted by the sound of the squeaky pickles by rubbing them together.
When a customer comes to the Krusty Krab, SpongeBob still looks like the Krusty Krab (gross and filthy), and Mr. Krabs is bright red like he should be.
The Pretty Patties loosely resemble the popular French dessert known as Macarons.
When SpongeBob is cleaning the Krusty Krab near the end, the drive thru window also seen in Driven to Tears is shown.
Various episodes show Bikini Bottom to have anywhere from no people to over 500 people living there. Many surronding cities must've had to come to Bikini Bottom to obtain a pretty patty.
On the Krusty Krab window, along with the picture of a Krabby Patty, there are also pictures of fries and a soda. In other episodes, there is only the Krabby Patty poster.
Like some fish food, especially goldfish food, Pretty Patties change the color of the fish that eat it.
The Comcast description of this episode refers to Pretty Patties as "colored crab cakes".
This episode has become a popular YouTube Poop.
46,853 (forty-six thousand, eight hundred fifty-three) is a five-digit prime number.
The color green seems to be pretty common in this episode as it was used as the main color for the background of the title card, SpongeBob had more green patties shown than any other patty, all of the money he and Patrick earned (and gave away), and the green glow-in-a-dark tongue of the customer.
In earlier showings of this episode, including the version available on iTunes, SpongeBob's first customer eats a blue patty. Now, he eats a purple patty.
Before SpongeBob gets interviewed, on the aerial view of their stand, SpongeBob and Patrick are just heads without bodies, behind their stand. During the interview, however, they are in front of their stand, full body.
After Mr. Krabs comes to see SpongeBob, Patrick's stand is no longer seen and Patrick is not seen for the rest of the episode.
When Mr. Krabs hands SpongeBob the key, the fish in the backround have no arms or clothes. Just eyes on sack looking things.
In Tom's first appearance in this episode, he is light green. But when Mr. Krabs is burying himself alive, Tom can be seen in the crowd in his normal, darker color.
They didn't need to chase Mr. Krabs for their money back because they were able to collect it for free before. Knowing Mr. Krabs, he probably didn't give their money back and took it home with him.
Mr. Krabs says that he has never had a line before, though there is a line at the Krusty Krab (in front of where Squidward works).
When SpongeBob first presents the Pretty Patty to Mr. Krabs, he attempts to dispose of it, believing it to be spoiled. Ironically, he went to ridiculous lengths to sell a spoiled Krabby Patty in Born Again Krabs.
When the fish gets the free money, he says that he is going back in line. However, he runs off in the other direction. He could have meant that he was going back in line to buy more Pretty Patties.
At the beginning of the episode with the fish that crawls into the Krusty Krab, he says he needs food and water. He would only need food because he is already underwater so he isn't dehyrated.
Some of the fish in the crowd were seen twice.
Mrs. Puff was seen in this episode standing in the back of the crowd. She was very skinny, her hair was longer and she didn't have any lines or movement. Her dress changed from solid blue to red with a blue collar several times.
In other episodes, Tom is a brown fish, but in this episode he is an aqua fish.
When the 3 kids say "And look at our tongues!", their voices are all high like a kid's should be. But when the fish with a glow in the dark tongue speaks, his voice becomes lower like an adult's voice and the two other fish that were with him disappear.
When SpongeBob wakes up and says, "Patrick! How long have we been sitting here?" SpongeBob's pineapple vanished.
