SpongeBob stays up late to watch Late-Night Horror Movie Madness, but is terrified and has nightmares. He wakes up in the middle of the night and thinks that monsters are out to get him and then he starts screaming. At his nightclub, he completely messes up the "Heebie Jeebies" dance move because he is so scared. He tries his hardest not to scream when he walks home but he runs away from a kid in a werewolf suit. When Patrick sees him to watch the sun rise, SpongeBob gets scared of him and hides in the bathroom, where it is dark and he screams so loud that the bathroom collapses. 2 hours later, at the Krusty Krab, he screams at everything and won't make Krabby Patties. He hurts just about everyone in the restaurant in his terror and finally destroys the Krusty Krab. Mr. Krabs gets angry and fires him and SpongeBob stopped screaming. But then SpongeBob starts crying since he lost his job. Soon, he bumps into Patrick, who tells him to attend his Scare Class.Later, Herk and Blobert explain why SpongeBob keeps on screaming. They show a few scary photos. Later, Dr. Drain watches Late-Night Horror Movie Madness with The Gobblers. Gobbler #1 (the dark green one) says, "I want to watch Horror Movies! I like horror films". SpongeBob, of course, gets scared and destroys Conch Street, so they have to have the Scare Class in Mrs. Puff's Boating School. Patrick tries and fails to stop SpongeBob's fear, but when he holds up a sign saying "Not Scary" SpongeBob loses his fear and doesn't scream anymore. Then, at the remains of Patrick's house, Patrick finds out that it is 9 o'clock so he can watch Late- Night Horror Movie Madness. SpongeBob hears the scary music from the remains of his house so he saves Patrick by shielding his eyes. However, Patrick asks if the scary part is over and peeps through SpongeBob's fingers, causing him to start screaming.
"Uh- oh, here comes more screaming," SpongeBob thinks. But when he catches his eyes on the movie he starts screaming again.
Herk and Blobert come again and say "You're screaming again". But later, Plankton changes The Chum Bucket into The Chum Bucket 2. Karen says "What about your Late-Night Madness". But Plankton says "I have customers to attend". SpongeBob holds the Not Scary sign again and stops screaming. He apologizes to all of the ones who was scared. He gets his goodness back. He works in The Krusty Krab. But he sees Dr Drain and The Gobblers trying to wreck The Krusty Krab. SpongeBob says that he will never come back until the destruction is over. But later, Dr Drain does screaming just because The "K" was missing and he thought it would be a retirement home. Mr. Krabs later lets SpongeBob get the job back. And this time he dances to the "Heebie Jeebies" dance move but Dr. Drain ruins it. But he meets the kid in a werewolf suit again but Dr. Drain scares it. During night, SpongeBob is in the bathroom but Dr Drain and The Gobblers burst through the door and they take him away to his lair. But SpongeBob escapes and all The Gobblers scream in sight there is no SpongeBob. When SpongeBob is at The Krusty Krab , making patties, Dr Drain destroys it. 2 hours later, He destroys the whole of Conch Street. In Mrs. Puff's Boating School, SpongeBob was almost passing the test but Dr. Drain destroys the school and the boats. When Dr Drain puts glue on SpongeBob's seat Gobbler #2 (the brown one with the bows) switches the Late-Night Mega Horror Movie Madness and hide the remote and tape him to the chair. Gobbler #3 (the light green one) covers SpongeBob's eyes while Dr. Drain ruins the Goo Lagoon sea forever. Then SpongeBob is not scared and he does the "Heebie Jeebies" again nicely, meets the kid in a werewolf suit and gives him a candy floss. He doesn't find anything except for Herk and Blobert. Herk says "Congratulations, you achieved your non-scream certificate" and Blobert says "Well done". SpongeBob goes to The Krusty Krab making the Patties and gives them to everyone in the restaurant. Plankton steals the formula and wins. He later replaces customers with cardboard cut-outs of people. But they turn into Herks and Bloberts. Herk clone #8 says "2 Krabby Deluxe" and he looked at the cost saying "1 dollar" and he pays and he says "Thanks". SpongeBob now is not screaming anymore. When he sees Herk again, Herk says "We banned Late-Night Horror Movie Madness". SpongeBob becomes happy. "The Krusty Kranium Game Show is on now". SpongeBob stays up late to watch The Krusty Kranium Game Show, but Mr. Krabs says "And the winner is....". SpongeBob is excited. "Me Number One Fry Cook, SpongeBob SquarePants!". All of the people visit SpongeBob's house and each one recieves a Patty Pal. SpongeBob is so excited. But 28 years later, Dr. Drain ordered Gobbler #1 to unban Late-Night Horror Movie Madness. But SpongeBob watches The Krusty Kranium Game Show again and so excited. The End
