Synopsis

It's Halloween in South Park again, and all is not well. Father Maxi denounces the holiday as evil, and expresses his disgust in inviting the band Korn to perform, which could only compound the evil that day. Korn and the rest of South Park start seeing pirate ghosts (or are they ghost pirates?) around the pier, making the concert a distinct impossibility. With the help of their space chicken friend, Niblet, Korn set's out to foil the ghosts evil scheme.

Full Recap

At the South Park docks, there is a huge Halloween Haunt sponsored by a local radio station and the band Korn is scheduled to make an appearance. While the other boys think about Halloween and its candy, Cartman is already focusing on Christmas being two months away. The 5th graders scare the boys (sans Cartman) with the legend of the pirate ghosts of the South Park docks. They boys decide they need to find a way to scare the 5th graders. The band Korn is en route to South Park to play at Chef's 2nd annual Halloween bash, but are spooked off the road by pirate ghosts. Cartman starts working on the Christmas list and is pissed off when his own mother laughs at the other boy's fat jokes. Stan has come up with a plan to scare the 5th graders; he suggests that they dig up Kyle's recently deceased grandmother. Kyle is against it, but the boys convince. At the graveyard, Cartman is singing Christmas carols, as they dig up Kyle's grandma. The remove her from her coffin and take her down to the docks. At the docks they meet the band Korn, who mention the pirate ghosts; the boys tell them the pirate ghosts are just the 5th graders that they plan on getting back at. Satisfied with that response the band wants to know where the stage is, the boys tell them and then the hide the body of Kyle's grandmother. They don't do a very good job, when a dog finds the body and grabs hold of the head.
Kyle's mother finds out that her mother's grave has been defiled; they believe someone is using her body for kinky sex. At the Cartman home, Cartman's mother receives a package, which Cartman believes will be a Christmas present for him, so he opens it. The package contains a life- anatomically correct Antonio Banderas blow-up doll. He proudly brings it down to the docks to show off to the other boys, where he meets Kyle dressed as a clown and Stan dressed as a cowboy. Kenny, who historically has always had the worse costumes, arrives dressed as ED-209 from the film "Robocop." Cartman goes to get grandma's body but they find that is gone. At city hall, a press conference is held to warn the citizens about the necrophiliacs, when a pirate ghost and ship appears warning the townspeople to stay away from the docks. The Halloween Haunt is cancelled and Korn is bummed and so are the boys, who tell the band about Kyle's missing grandmother. The band thinks the two events are related and they decide to help the boys solve the mystery. Meanwhile, the townspeople, through the prodding of Priest Maxi decide that the appearance of the band Korn is the reason bad things are happening in South Park. They form a lynch mob to go after the band.   Louis J. Sheehan, Esquire
Korn and the boys split up to search for clues; meanwhile the angry mob trashes their van. One group sets up the trap for the ghosts, using the Antonio Banderas blow-up doll, while the other group actually encounters a ghost and runs into the trap.  Louis J. Sheehan, Esquire  The angry mob arrives as the three pirate ghosts appear. Korn uses their special Korn powers which turns them into useless variations of corn. Korn's special friend Nibblet captures the ghost, but the ghosts manage to disappear. Nibblet then finds the real culprit, Priest Maxi. Korn then shows them how Priest Maxi did it. With one mystery solved, the other mystery is solved when a dog appears on the scene and throws up the body of Kyle's grandmother. The townspeople ask Korn to stay and play their Halloween festival.

Korn performs a song they wrote for the occasion, as Stan and Kyle scare the 5th graders; Nibblet pops the Antonio Banderas blow-up doll and Wendy wins the costume contest AGAIN with her Chewbacca costume.
Kenny dies during the end credits when his Halloween costume is tripped up and destroyed by small rebel fighters a la "The Empire Strikes Back."
