This horror (yet funny) YTP starts with SpongeBob and Patrick enter a tent where they see a rolled up paper, while some images of scary jumpscares pop up. After unrolled the paper, the two realize they recognized something on the paper, but all of the sudden, Mr. Krabs, armed with a chainsaw, appears behind them, and the screen turns black as SpongeBob and Patrick screams. It flashes back three days earlier when a health inspector showed up at the Krusty Krab for an inspection. The fish anchor informs the health inspector was a fake and just wanted "FREE food". Enraged, Mr. Krabs decided to kill the health inspector by tainted the Krabby Patty with poison. SpongeBob, who is forced to assist, gives the Patty to the health inspector. Then the health inspector eates the poisoned Patty and died. At a dark night, Mr. Krabs and SpongeBob go to muddy hill where they buried the health inspector's dead body so nobody will know about the murder. But then a police car came around and the cops caught Mr. Krabs and SpongeBob. As it turned out, they just wanted some Krabby Patties. Unfortunately for the cops, Mr. Krabs was too panicked from being caught, he began shooting at the cops with an sub-machine gun, then a flamethrower, which set fire to the police car and explodes, killing two officers.
As Mr. Krabs laughed maniacally, a scared SpongeBob is suprised of what Krabs have done. Mr. Krabs was not the man he used to be, and this was just the beginning of a living nightmare. Later that night, after what happened to the health inspector and the two police officers, Mr. Krabs had a nightmare of a morbid sprite of himself telling him to kill more people. This causes Mr. Krabs to lose his sanity as he acted that way at the Krusty Krab the next day, trying to stop the voices in his head. Squidward, notice Mr. Krabs' insanity, tells SpongeBob to call the Navy, while he evacuates the customers. After, SpongeBob and Squidward goes to Mr. Krabs' office to attack him and tied him up. Then the police appears from the ceiling and arrests Krabs, sending him to the Bikini Bottom prison.
In the prison, Mr. Krabs, who is becoming more insane than ever, dramatically monologing himself on how SpongeBob and Squidward betrayed him and have him sent to jail. Then, Krabs slowly evolved into Moar Krabs.
Meanwhile, while walking home, Squidward admitted to feeling remorseful for getting Mr. Krabs arrested, but saying it will pass. As he relaxes, Squidward then has a nightmare about Mr. Krabs burning down the Krusty Krab with SpongeBob in it, thinking he will return for revenge. Back at the prison, two prison guards noticed and goes to Mr. Krabs' cell when he rips the skins off of them, bleed them to death. Mr. Krabs goes through the tunnels, escaping jail.
Meanwhile, Squidward had boarded up his front door as protection against Mr. Krabs and then taking a bath. But while Squidward was scrubbing his backside, an axe broke through the door in the style of The Shining, causing Squidward to scream. Then Mr. Krabs appeared, killing Squidward with the axe. The next day, while SpongeBob and Patrick were taking a stroll in town, they received the newspaper inform Mr. Krabs' murder to Squidward, realizing Krabs is on a rampage in Bikini Bottom. The two decide to run away from Bikini Bottom if they remain to prevent Krabs to hunt them down.
However, SpongeBob and Patrick find a tent where they discover a collection of decapitated heads, buckets full of blood and murdering weapons. When the duo unfolds the paper they find a head of Squidward with the words below saying, 'gotta have MOAR'. Suddenly, Mr. Krabs appeared with a chainsaw. The enraged Mr. Krabs began to chase SpongeBob and Patrick through the fields. They ran toward Bikini Bottom, but Mr. Krabs caught Patrick with a lasso and pulled him away to his doom. SpongeBob made it home, but Mr. Krabs wasn't far behind. After calling SpongeBob on the phone, breathing heavily into it, and hanging up, and after cutting off SpongeBob's electricity, Mr. Krabs broke in through the door with Patrick's skin and corner SpongeBob with a kitchen knife.
But then Mr. Krabs broke off SpongeBob's pants with his knife, revealing a bomb strapped to him. When Mr. Krabs asked SpongeBob what he was doing with it, SpongeBob says he is doing "something he should have been done a long time ago!" Then, the bomb denotes and exploded, killing both Mr. Krabs and SpongeBob, who sacrificed to end Krabs' rampage.
After the credits finish rolling, Patrick is seen saying "And everyone died. The end!" revealing that the whole video was just a scary story. A very disturbed SpongeBob then says, "F**k you, Patrick," ending the video.
