Hummels & Heroin
Beloved entertainers are being cut down in their prime due to massive overdoses of opiates. Stan is about to be exposed as the source of the illegal drugs.
A new boy in town named Marcus Preston has a birthday party where a costumed character entertainer of Chuck E. Cheese vomits and dies from having overdosed on painkillers. Stan goes to Shady Acres retirement home to visit his Grandpa Marvin Marsh and brings him a present of a Hummel figurine. Grandpa tells Stan he must deliver a pillow made by another resident, Ms. McGillicudy, who has become the "top bitch" at the home. Stan later exchanges it for a limited-edition Hummel with another costumed character of Swiper the Fox. At school, Marcus hosts an assembly mourning the recent deaths of multiple costumed characters due to overdoses from painkillers, including the now-deceased Swiper.
Stan realizes he has unknowingly been a drug mule, as the boys try to convince Stan to turn in his Grampa. At the retirement home, Granpa explains to Stan that McGillicudy's collection of Hummels has put her in power, as she vaguely threatens both Stan and Grampa if they do not cooperate with her. Marcus visits a coroner's office for the autopsy of Chuck E. Cheese where the coroner reveals that the entertainer, along with all of the other recently deceased costumed characters, had Hummels stashed in his anal cavity.
Marcus confronts Stan about his recent increase of Hummel purchases and threatens to expose Stan if he is involved. Stan begs the boys for help, as he plans to steal McGillicudy's Hummel collection and give them to Granpa, thus making him the one in charge, so Cartman comes up with a plan. Marcus rushes to another birthday party where a costumed character of Peppa Pig reveals to him the connection between Hummels and old people before Peppa dies.
At the retirement home, the boys dress as a barbershop quartet while Stan finds McGillicudy's room and puts the Hummels into a large sack. There, he is confronted by Marcus but Stan convinces Marcus to instead go after the people really responsible for the death of Chuck E. Cheese. Stan brings the sack of Hummels to Grampa but is confronted by McGillicudy. Grampa uses the sack of Hummels to beat down McGillicudy and her companions, earning the respect of everyone else in the nursing home, while Marcus visits a convention of pharmaceutical doctors to ask them some questions.
