Nobody Got Cereal
In continuation from the previous episode, the demonic monster ManBearPig continues his rampage through the town of South Park, brutally murdering and consuming citizens in broad daylight. Fourth grader Stan Marsh and his three friends, Kyle Broflovski, Eric Cartman and Kenny McCormick, are in a jail, having been arrested by Sergeant Harrison 'Harris' Yates, who believes that the recent murders were the result of school shootings perpetrated by the four boys. Exploiting their guard's obsession with the video game Red Dead Redemption 2 (a pastime popular among the townsfolk that serves as a recurring reference throughout the two-episode story), Stan and his friends escape jail. When he learns that his grandfather, Marvin Marsh, has been talking about ManBearPig since Randy was 14, Stan confronts him. Grandpa Marsh reveals that when he and his friends were young and foolish, and South Park was a smaller town, they made a deal with ManBearPig for luxurious things like expensive cars and premium boutique ice cream, not thinking about the future, or what this would mean for their grandchildren.
Sergeant Yates continues to deny the existence of ManBearPig, insisting that the gruesome crimes are the result of school shootings. Stan and his friends reconvene in the woods with their allies, former U.S. Vice President Al Gore, who first warned the town of ManBearPig in the episode "ManBearPig", and Satan, whom the group summoned in the previous episode to inform them of ManBearPig's origin. After contending with the haughty and self-satisfied Gore's continued self-aggrandizement, Cartman convinces Satan that it is time that he did something for the people of South Park, who lately have been doing a lot of his work for him. Satan confronts ManBearPig in a furiously violent brawl in the middle of town, but is fatally beaten, and ascends to heaven as an angel.
Grandpa Marsh takes refuge with Stan and his friends at South Park Elementary, where they are surrounded by the police. However, Sergeant Yates appears and admits that he has been a fool by denying ManBearPig's existence, and did not realize this until he saw the effect that his stubbornness had on his marriage. Yates muses that it is never too late to do the right thing, and ask Stan and his friends if they know what that is. Stan says that they do, and will put an end to the deal once and for all. He and his friends are given power of attorney to represent the town, and enter sit-down negotiations with ManBearPig and his attorney to void their prior deal. ManBearPig agrees to leave the town and never return, in exchange for compensation, including the town's agreement to give up soy sauce and Red Dead Redemption 2, but the town's reluctance to do this merely leads to continued negotiations, and increased demands by ManBearPig.
Quite a few new characters appear in this episode, with most of them connected to the townspeople's confusion over when they should begin to start to worry. We also meet a new police officer, Jenkins, some forensic scientists employed with the Police, and Manbearpig's lawyer.
The boys' recruit Satan to save the town and humanity from the threat of Manbearpig. (Gore's assertion Satan sent Manbearpig is not addressed.) After a dangerous and cinematic battle between the two beasts on Main Street, Satan is killed; if there's any doubt it's permanent, we see him as an angel ascending to Heaven as an angel, to live alongside God, his ex and the Mormons.
- In the previous episode, Al Gore asserted that it was Satan himself who had created and sent Manbearpig up to Earth, but no reference is made to this connection in this episode.
- We meet television host Jim Kimble in this episode; years ago in "My Future Self n' Me", we learned that Sharon Marsh's maiden name was Kimble.
- Stan once again mentions that Manbearpig "took Ned" but his fate is never clarified; despite their longtime relationship, Jimbo Kern appears in the crowd scenes in this episode completely unaffected by the loss.
