Korn's Groovy Pirate Ghost Mystery is the 12th episode of the 3rd season of South Park.

Synopsis
It's Halloween, and Stan, Kyle, Cartman, and Kenny dig up Kyle's dead grandma to scare the 5th Graders. Korn comes to town and a mystery involving pirate ghost begins...

Plot
At the docks, the boys inspect the preparations for the "Halloween Haunt" but deem it gay. Cartman meanwhile is too busy looking forward to Christmas. Priest Maxi tries to inform people about the evil of Halloween but is ignored. The boys bump into the 5th Graders who terrorise them with the story of the pirate ghosts.

The boys try to come up with a way to scare back the 5th Graders, and decide to dig up Kyle's dead grandma. They do this and hide her at the docks.

The wardens at Mount Peaceful Cemetery inform Sheila Broflovski of the defiling of her mother's grave and suspect it to be the work of necrophiliacs.

Meanwhile, the band Korn show up and tell the boys about their encounter with pirate ghosts on their journey. The boys explain they're trying to get back at the 5th Graders since it is seemingly their work.

At the town hall, a meeting is held outside where the wardens of the cemetery consult everyone about the necrophilia. Suddenly, a pirate ghost ship appears in the sky along with three pirate ghosts who begin to kill the crowd. They soon vanish after warning everyone not to go to the docks. Priest Maxi then shows up and explains he was right and the town decides to drive Korn out of town.

Later on the boys show up in Halloween costumes, except for Cartman who has his "christmas present", an Antonio Banderas blow-up doll. Korn soon discovers they have a mystery to solve. They theorize that the pirate ghosts may be linked to the disappearance of Kyle's dug up grandma, who is not where the boys left her. They split into two teams and begin to seek the truth. After an encounter with pirate ghosts, the trap set goes wrong after an unfortunate accident with one of the teams. The townsfolk suddenly burst in and the pirate ghosts appear. Korn use their "Korn powers" which are ridiculously useless.(but it looked cool) However, they are able to catch the pirate ghosts in a net. As the true identity of the ghosts are about to be revealed, they disappear suggesting they really are pirate ghosts. Korn's pet Nibblet opens a trap door uncovering the true villain, Priest Maxi. Although that case is solved, the whereabouts of Kyle's grandmother are still unknown. A dog then shows up and vomits up Kyle's grandma's corpse.

In the end, Maxi is arrested and the town invite Korn to stay and play at the concert. The boys scare the 5th Graders with the corpse. Nibblet pops Cartman's doll. Kenny fails to win the costume contest and loses to Wendy Testaburger,(who won with the chewbecca-costume ...again) only to be blown up.
