Like many routine Christmas specials, this episode has a rhyming narration akin to a storybook. It begins in a forest, where
Stan Marsh discovers a group of talking animals, known as the Woodland Critters, consisting of Squirrely the
Squirrel, Rabbity the
Rabbit, Raccoony the
Raccoon, Beavery the
Beaver, Beary the
Bear, Porcupiney the
Porcupine, Skunky the
Skunk, Foxy the
Fox, Deery the
Deer, Woodpeckery the
Woodpecker, Mousey the
Mouse, and Chickadee-y the
Chickadee are building a
Christmas tree. They convince a surprised but
apathetic Stan to help make a star for it, after which he goes home. That night, they wake him in his room and explain that Porcupiney is
pregnant with the creatures' savior. Though tired and annoyed, Stan agrees to help them build a
manger for the baby. As he finishes, however, another problem appears: a
mountain lion, which eats every pregnant Critter to prevent their Savior's birth. Exasperated, Stan goes to the cave where the mountain lion lives and manages to kill it, but is dismayed to learn that the mountain lion is the mother of three now-orphaned cubs. He is further horrified to learn that the Woodland Critters are
Satanists and that their "Savior" is the
Antichrist. They celebrate Stan's victory by sacrificing Rabbity, devouring his flesh, and having an
orgy in his blood. Stan tries to ignore the impending apocalypse, only to be goaded by the
narrator into trying to stop it. Unfortunately, the Critters can rebuff him with their Satanic powers, which will grow more vital as the Antichrist's birth approaches. Since the Critters claim that only a mountain lion can prevent that, Stan, heeding the narrator's instructions, returns to the mountain to enlist the orphaned cubs. Since they are too small to take on the Critters, they can only stop the birth by learning how to perform an
abortion. The narrator forces Stan to take them to an abortion clinic for lessons, despite his objections. Meanwhile, the Critters are searching for an
unbaptized human host for the Antichrist to possess once it is born. They discover
Kyle Broflovski, who reveals to the Critters that he does not celebrate Christmas because he is
Jewish, and lure him into the forest. Stan and the cubs return to the forest, only to discover that the Antichrist, a hairless, jabbering little creature, has already been born, with Kyle tied to a Satanic
altar. When he learns what is happening,
Santa Claus arrives, pulls out a shotgun, and kills all the Critters. Stan explains that the Antichrist will die without a human host to inhabit, but Kyle, having been freed, suddenly decides to allow the Antichrist to possess him. He declares that he will conquer the world in the name of the Jews, allowing them to finally take control of Christmas once and for all. The scene suddenly cuts to
Mr. Garrison's fourth-grade class, revealing that the narration had been from a Christmas-themed story narrated by
Eric Cartman for a school assignment. Kyle objects to its blatant
antisemitism, and Mr. Garrison, fearing complaints from
Kyle's mother Sheila, forces Cartman to stop reading. However, the rest of the class, including Stan, wants to hear how the story ends and plead with Kyle to let Cartman finish. Kyle objects that the ending is obvious, as he assumes Santa Claus will simply kill him, thus saving Christmas. Cartman insists that the ending is different, and Kyle reluctantly allows Cartman to continue. In the story, Kyle becomes horrified at how evil the Antichrist feels and begs the others to exorcise it before it takes control of him. Santa believes it is too late and is about to kill Kyle, but Stan has the mountain lion cubs perform an abortion through Kyle's anus, allowing Santa to smash the Antichrist with a sledgehammer, killing it. Santa gives Stan a special Christmas wish, which he uses to resurrect the mother mountain lion, who is happily reunited with her cubs. Everyone then goes home to a happy Christmas. The narrator concludes, "and they all lived happily ever after... except for Kyle, who died of
AIDS two weeks later," with an image of an AIDS-stricken Kyle dying in a hospital bed. The episode concludes with "The End," while Kyle can be heard angrily shouting "Goddamn it, Cartman!" ==Production==
