Following more attacks by the mummy, Butters meets with the school counselor, Mr. Mackey, but is incredulous to learn that undead being has also spoken to Mackey, who expresses a sympathetic view of the creature. Butters later meets with his classmates at a fast food restaurant, and tells them that he needs to end the curse, pointing to the endless texts and selfies that Took-Tan-ra sends him, but his classmates, like everyone else, speak as if the fault lies with Butters, and advise him to break things off with him, even as the mummy shows up there to continue his campaign of harassment.
Shelly cooks a witch's brew, and recites an accompanying incantation that will grant her revenge. She dumps the brew onto his Halloween Special marijuana, horrifying Randy and his business partner, Towelie. This turns out to be an enhanced growth formula that increases Randy's yield. However, when he refuses to drive Shelly to a book fair on Halloween night, she destroys the packaged Halloween special, prompting Randy to ask the police to put her in jail for the night. She is placed in a cell with Butters, who has been imprisoned because he, not the mummy, "manipulates the mummy with his passive-aggressive selfishness".
At Randy's party, the revelers who smoke the Halloween Special mutate into monsters. Randy is then confronted by an undead Winnie the Pooh, whom Randy murdered in the episode "Band in China". Other monsters follow, including an unseen Harvey Weinstein who rapes Randy during Randy's phone call to the police. The police race to Tegridy Farms with Butters, in the hopes that he can use his powers of manipulation to stop the mummy, whom they believe is causing the attacks there. However, the horrors Randy experiences are revealed to be an hallucination caused by the mutated marijuana. Shelly ends these hallucinations by brewing an antidote that she throws at Randy. The ranking policeman there, Harrison 'Harris' Yates, informs Butters that the mummy was not to blame for the emergency. Butters apologizes to the mummy, who gives Butters a note written in hieroglyphics before leaving for good. Butters learns the note reads, "I hope you can get the help you need. I can't fix you." Randy awakens three days later, and when his wife, Sharon says he was the only one who enjoyed the Halloween special, he says that he was pretty much the target audience anyway. He is also relieved that he did not really have anal sex with Harvey Weinstein, though he and the family are shocked to find a used condom that gives cause for them to question this.
