Korvo and Terry place nanobots in the city's water supply to spy on their neighbors. Learning they are not well-liked, Korvo and Terry use the information from the nanobots to win over the community, and run for president of their homeowner association. The nanobots form a sentient person that runs for president as well, and all three expose embarrassing secrets about their neighbors, who break out in violence. The incumbent president Ruth restores order and turns the crowd against Korvo, Terry, and the nanobot person, who escapes from Korvo.

Korvo tries to get the family involved in repairing the spaceship, but they attend a birthday party instead, where he is inspired to become a magician. Using his computer system Aisha, Korvo creates a technologically advanced magic act; he goes viral and prepares for a Las Vegas show, which will culminate in him leaping through a black hole. Korvo ignores his family's warning that jealous magicians plan to kill him; the family save him from being shot, but he dies when the black hole trick goes awry. The grieving family agree to repair the ship in Korvo's memory, and he reappears, having faked his death to bring them closer together. Yumyulack adds a woman named Cherie to his shrunken collection.

Korvo, increasingly frustrated by Terry, vomits a "red Goobler" – a stress-induced creature intent on killing Korvo. They buy a Jet Ski from Trent, who is killed by the Goobler. Hunting the creature inside a Halloween store, they shrink and capture it. At school, Jesse discovers a flower growing on her head, which releases pollen similar to MDMA, making the popular girls enamored with her. Yumyulack accompanies Jesse to a party and discovers his own flower, with pollen similar to cocaine, and bonds with the popular boys. The mix of Yumyulack and Jesse's pollen creates an effect similar to PCP or bath salts, turning the party-goers bloodthirsty and deranged. Jesse and Yumyulack inform Terry and Korvo, who explain the flowers are a temporary fungus.
