It's Halloween and Cartman is acting weird. Sometimes he's his regular, obnoxious self, endlessly saying the word "hella." Other times he shows such un-Cartman-like traits as compassion and consideration for others. Speaking of weirdness, Stan's mother Sharon tells him that her Aunt Flo, who visits each month, has given him a fish as a present. A The fish that murders people at night. Sharon, convinced Stan is the killer, dutifully buries the bodies to cover her son's tracks. She even kidnaps Officer Barbrady when he comes snooping around and keeps him, pants-less in the basement. The fish also kills Aunt Flo, and of course, Kenny.
The boys discover that Cartman is actually two separate people. The "good" one is from an evil parallel universe -- as is the pet fish. They promptly return the fish to the Ancient Indian Burial Ground Pet Store (where the portal between worlds resides). They learn that nine other "evil" pets, complete with glowing red eyes, have already been returned.
After they leave, versions of Stan and Kyle cross over from the parallel universe. They release the evil pets, which go on a killing spree. They also ally themselves with the "real" Cartman from this world and go gunning for Stan, Kyle and parallel-universe Cartman. After a vicious struggle the evil Stan and Kyle are vanquished back to their own world using a "gingerfication gun." But the good Stan and Kyle -- who want to send their Cartman back to the evil parallel universe and keep the alternate Cartman -- lose track of which is which and don't know who to blast. One of the Cartmans says they should shoot them both, just to be sure. Figuring only alternate-universe Cartman would be capable of such altruism, they zap the other one instead. Mistake. They're stuck with the "real" Cartman, who figured the two would fall for such a lame ruse.
- "Man, you guys are hella stupid." Cartman
- "Hush little baby, don't say a word, momma's gonna buy you a mockingbird. If that mockingbird don't sing, momma's gonna bury it in the backyard “Sharon Marsh
- "You guys are my best friends! Through thick and thin, we've always been together! We're four of a kind! Havin' fun all day! Pallin' around and laughin' away!" Evil Cartman
- "You guys can kiss my black ass." Cartman
- "I've got such a good boy, such a handsome boy” Sharon Marsh
- "You kick ass Evil Cartman!" Kyle
- "Let's see I hate you guys. You're hella-stupid” Cartman
Close to a dozen people (including Kenny and Aunt Flo) finished off by the Spookyfish. The other evil pets also claimed an undetermined number of South Park residents.
Behind The Scenes
Pop Culture References
Evil Stan, Kyle and Cartman all have goatees -- a reference to the Star Trek episode Mirror, Mirror, in which an evil, alternate-universe Spock sports similar facial adornment. Also, when Kyle remarks about a puny squash Kenny wanted to use for a pumpkin-carving contest, he says, "I never thought it was such a bad little squash. It just needed some tender loving care." It's a direct reference to a similar line in A Charlie Brown Christmas.
The notion of a murderous pets coming out of an Indian burial ground borrows from Stephen King's horror story Pet Sematary. Furthermore, the closet doorway that holds an entrance to the parallel universe is a reference to the cult classic film Poltergeist.
Barbara Streisand, again. After being savaged in "Mecha-Streisand", her image is emblazoned on all four corners of the screen, along with the words "spooky vision," during the entire episode. Her "spooky" picture changes 4 times throughout the show; a different picture is shown in each act.
When Officer Barbrady shows Stan's mom photos of people who have gone missing, the lineup includes a shot of William Shatner.
When Cartman and Evil Cartman appear in the same scenes together, there is a clear seam in the animation to give the effect that the image was crudely mirrored. This was done on purpose, as a tribute to shows and films that actually used this old-school effect.
The boys can't stand Cartman's constant use of the term "hella" in this episode. However, when Bebe sprouts boobs in "Bebe's Boobs Destroy Society", she uses the term "hella" and everyone loves it.
