There have been a bunch of Christmas episodes of South Park but only four Halloween episodes come to mind.Pinkeye is the first Halloween episode of South Park.I think its great! It's fairly funny and has lots of gore with the South Park kids killing zombies! Basically it's Halloween in South Park, a space shuttle kills Kenny and he is sent to the morgue.There after a drainage gone wrong, he becomes a zombie and bites the two people at the morgue, they then go on to bite people and pretty soon, most of the town becomes zombies.Though they mistake it for Pinkeye.Meanwhile, Kyle is dressed as Chewbacca, Cartman as Hitler and Stan as Raggedy Andy.Stan dresses like that so Wendy will dress as Raggedy Ann and they can enter the costume contest together where the first prize is a lot of candy.Wendy dresses as Chewbacca instead and Stan gets ridiculed by everyone.Cartman gets in trouble for his Hitler costume and the principal makes a ghost costume for him(only it looks like a Klansman).They go trick or treating but everyone is a zombie, so with the help of Chef, they must find a way to turn everybody back to normal.Pinkeye is a great Halloween South Park episode!
