"The Krusty Slammer" is a SpongeBob SquarePants episode from season twelve. In this episode, Mr. Krabs turns the Krusty Krab into a jailhouse after Plankton breaks the law, but crime only pays for so long.



The episode starts with Plankton vandalizing the Krusty Krab and all parts of town with pictures in an attempt to make people think that Mr. Krabs is a jerk. However, he is arrested by the lady officer, who reveals that vandalism is a crime after he protests that he did not steal anything too. She walks him to prison, with a gloating Mr. Krabs tagging along.

However, the jail is full, so the lady officer sends him free. She then says that she wishes that someone could open a second jail in Bikini Bottom, and that she could give them a myriad of money. Mr. Krabs hears this and takes the offer. The lady officer drops a wrecking ball on Plankton, and gives Mr. Krabs the money.

Plankton as Mr. Krabs' prisoner.

Mr. Krabs rolls around the wrecking ball with Plankton tethered to it to the Krusty Krab, hitting Squidward while he is scraping gum off one of the tables! Mr. Krabs then announces to the Krusty Crew that he's converting the Krusty Krab into a prison. SpongeBob gets excited, but Squidward doesn't care. Mr. Krabs tells them both to get back to work while he deals with Plankton. He is then seen in his office, putting Plankton in a bird cage. However, Plankton tries to trick Mr. Krabs to leave the room by saying there is a penny on the floor but this plan fails, and Mr. Krabs gets very sad. As a result, he decides to give him a bigger punishment.

Mr. Krabs goes to SpongeBob, who is cleaning, and puts Plankton inside of SpongeBob through the holes. He then plugs SpongeBob's hole, and SpongeBob laughs. The lady officer then appears, saying that she's got more money to give for more prisoners. The prisoners come out of the van that appears in front of the Krusty Krab, all acknowledging that they've been to the place before. Mr. Krabs accepts and receives the money, and then asks SpongeBob to add cells to the restaurant.

The Krusty Krab is then turned into a prison, although Fred dislikes the change. Mr. Krabs then announces a new restaurant then and menu item related to the new prison, as one of the prisoners likes the idea. He then decides to let Plankton out of SpongeBob. When he pulls out the plug and sees that Plankton has become hysterical inside SpongeBob, Mr. Krabs takes out Plankton, and then cuts to him putting Plankton inside the Krabby Patty secret formula bottle and takes out the formula itself so Plankton can fit. Plankton becomes sad since he's so close to the formula yet so far, and Mr. Krabs smiles.

SpongeBob is then seen giving out mail to all the prisoners, which there is plenty of. Mr. Krabs is then seen giving punishments to Plankton in multiple forms, until the lady officer comes and says Plankton's sentence is up. Mr. Krabs is upset as he says he wanted to give more punishments, but Plankton comes out and says to enjoy a prison without him. He then runs away, saying that he hopes the prison is worth what he's paying for it.

Mr. Krabs does not understand, until he realizes that all the prisoners have expensive items in their cells and are having Krabby Patties. Mr. Krabs gets mad and asks SpongeBob what he is doing, since it costs a lot to make the prison look humane. Mr. Krabs then takes away all of the comforts SpongeBob gave to the prisoners and takes out the Krabby Patties of two prisoners and shoves them into a regular customer and takes their money. Mr. Krabs says that from now on, patties cannot be served to prisoners, but the prisoners get mad and throw tomatoes at him for his actions. The customers get annoyed by this as well, and leave the restaurant.

Having lost business, Mr. Krabs angrily releases the prisoners...

Mr. Krabs gets sad from the customers leaving the restaurant, and decides to let the prisoners go from their cells and pushes them out of the restaurant. Mr. Krabs orders them to leave his business. He then comes back into the restaurant, relieved, saying the problem is resolved. He then throws a protesting SpongeBob back into work. Later that night, the prisoners come inside SpongeBob's house at night while he is sleeping, and they wake SpongeBob up. SpongeBob asks why they came into his house, and they say that they miss being at the Krusty Krab, since they were having fun with SpongeBob. SpongeBob then decides to do a jailbreak-in to get the prisoners back into the Krusty Krab into their cells.

...however, Mr. Krabs becomes Plankton's prisoner as a result of his act.

The next day, Mr. Krabs walks to the Krusty Krab to start another day, and when he comes in, all of the prisoners say good morning to Mr. Krabs. Mr. Krabs obliviously says good morning to them back, until he realizes the situation at the moment. He then gets mad at SpongeBob because he sent all the prisoners away the previous night, but asks him why they were placed back in their cells. A nervous SpongeBob tells him it wasn't the best time to say that, as the lady officer, who is sitting at a table eating a Krabby Patty overhears this. She reveals to Mr. Krabs that it is actually a crime to set prisoners free early ahead of time like he did and arrests him for admitting his act. At first, Mr. Krabs is shocked to learn this news but becomes okay with it, since he thinks that he'll be put in the Krusty Krab prison, while telling SpongeBob to set a massage appointment for him. However, the lady officer states that since the Krusty Krab is full, she's putting him in a new prison meant for just him. A defeated Mr. Krabs already knew where he was headed.

The episode ends with Mr. Krabs in a birdcage at the Chum Bucket, with a gleeful Plankton getting revenge on him for his earlier torture by throwing chum at the crying Mr. Krabs.


The episode was confirmed by Vincent Waller on December 11, 2018.[1]
