"Jewpacabra" is the fourth episode of Season Sixteen, and the 227th overall episode of South Park. It aired on April 4, 2012.
South Park's big Easter egg hunt is in jeopardy when there are rumors of a dangerous beast lurking in the woods nearby. Cartman tries to warn everyone that their lives are at risk if they participate in the egg hunt. No one believes him until he produces video evidence of the mysterious being.
Kyle Broflovski is seen waking up and getting cereal. While walking towards the table, Kyle realizes his mother is talking to Cartman about Passover. Kyle angrily tells him to leave; Cartman obliges, but not before telling him about a creature that is set to make Passover very memorable.
Afterwards, several children are seen signing up for the Sooper Foods-sponsored Easter Egg Hunt. Eric Cartman is seen warning several boys about the "Jewpacabra", a monster that preys on children during Passover, which happens to be the same week as Easter this year. This upsets Kyle, who proclaims that only liars or stupid people would believe in a Jewpacabra.
Butters is shown in his bedroom, frightened over the possibility of the Jewpacabra's existence. Shortly after this, Cartman appears in his room. After speaking with him, Butters agrees to go look for the Jewpacabra. After this, Butters is seen in the forest with Cartman, attempting to lure the Jewpacabra out with its anti-Jesus Christ "mating calls".
Cartman is seen at Sooper Foods, attempting to get the business owners to cancel their Easter Egg hunt because of the danger of the Jewpacabra. After showing them a supposed video of the creature, Mr. Billings, the Sooper Foods president, decides to give Cartman all the resources he needs in order to capture the creature. After abusing this to go to a water park, he takes the supposed video to cryptozoologists, who misguidedly confirm it's validity, scaring Cartman.
Later that night, Cartman is seen in his bed, scared at the possibility of a Jewpacabra actually existing. Later, Cartman is seen in the South Park Church, with Butters Stotch, Craig Tucker, and Token Black guarding the entrance. After hearing something being knocked over, the boys run, leaving Cartman inside the church. Something begins to attempt to get in, frightening him. It turns out to be Mr. Billings and his employees, who kidnap him, dress him up in a bunny suit, and leave him in the park.
Mr. Billings and the employees are seen at Kyle's door, telling him that there is a sacrifice at the park, to appease the Jewpacabra. Kyle later goes to the park, telling Cartman if he admits the Jewpacabra isn't real, he'll free him. In his fright, Cartman admits that he truly believes one exists, causing Kyle to leave without freeing him.
Afterwards, Cartman is seen in the park through a pair of what appear to be red, slanted eyes. However, it is revealed that they are simply binoculars being used by the cryptozoologists, who mistake Cartman for a "Bunny-man." They tranquilize him, later leaving with the intention of getting a show on Animal Planet about their supposed encounter.
Cartman is shown in Ancient Egypt, where the biblical plagues are taking place. Kyle is shown to be within this dream as well. Cartman questions Kyle on the plagues, who reveals that they are happening because the Pharaoh will not let the Jews go. Cartman says he will attempt to get the Pharaoh to let them go, however, Kyle objects, saying that God will "harden" the Pharaoh's heart, so he will not be able to be convinced.
Cartman attempts to convince the Pharaoh, who turns out to be his father, to let the Jews go, however, he fails in this attempt. After witnessing several Jews slit the throats of lambs and several children dying, Cartman and the Pharaoh realize they were wrong. Cartman promises to be Jewish, shortly before his head explodes.
Kyle, after his conscience got the best of him, frees Cartman and takes him to his bed. Later, at the Easter egg hunt, Cartman is shown attempting to convince everyone to convert to Judaism, seemingly have converted himself. After failing, he attempts to sympathize with Kyle, saying he finally understands how he feels about being laughed at because of his religion. Kyle nonchalantly responds. While positive music plays in the background, the scene rises to a shining sun with a Star of David at its center.
