Jack successfully gets to the supermarket and finds two shopping carts, along with some Capri Sun. When he pauses to grab it, he accidentally topples the shelf, which causes several other shelves to topple. They break through the windows of the store and the zombies start clambering inside. Just then, the King Wretch swoops down and eats several dozen zombies, and Jack wonders if it was trying to save him. 

The King Wretch plunges Jack into another vision, but this one is dark and terrifying. Jack sees all his friends dead and the tree house on fire. Just as he is about to open the door, a monster named Skaelka pulls Jack out of the nightmare. They walk back to the tree house together, and Jack can’t help feeling rattled and confused. He knows now that the visions aren’t of guaranteed events but of possible ones. Jack continues to wonder why the King Wretch is showing him these things and determines to find out.

Back at the tree house, Jack tries to put the issue aside and get excited for Funland. Conveniently, Dirk is finished building the newest contraption, the “Biggun Mobile.” The device is two large shopping carts attached to Biggun’s back. Quint looks at Jack and can tell how important this adventure is to him, and June grabs the radio before the group heads out.

Everyone climbs into the Biggun Mobile and Biggun tromps down the highway toward Funland. June compliments Jack on his devotion to his friends and his willingness to do anything for them. When they reach Funland, Jack is thrilled and impatient to get started. The kids walk through the park, admiring all the rides, and Dirk finds a way to get the power running. Soon, the kids are riding all of their favorite rides and playing carnival games. Jack is convinced it is the most fun ever and becomes extremely disappointed when he sees that his friends are still focused on the radio. Jack becomes overwhelmed and breaks down, ranting about his friends’ needs and the radio’s potential to destroy their friendship. He holds it up over his head and thinks about destroying it. His friends all look at him with serious disappointment, so Jack relents. Suddenly, the radio starts broadcasting a message.

Jack shakes as he puts the radio down. The person on the radio announces a final broadcast scheduled to take place at 10 in the evening. The signal is weak with all of the amusement park equipment around, so the kids aim to head for the top of the biggest roller coaster. When the King Wretch appears, the kids hide inside a food stand and decide their next move. Jack feels embarrassed and apologizes for panicking. He explains his worries about losing his friends when they find their families. June, Dirk, and Quint reassure Jack and remind him that they will remain friends no matter what happens or where they end up. Jack finds this realization comforting and is emboldened to finally open up about the visions from the King Wretch. He believes that the King Wretch wants something from him and knows he has to face it.

With the kids at the top of the roller coaster, the King Wretch swoops down and strikes with its tail, damaging the radio. June panics, but Dirk and Quint promise to fix it. Jack decides it’s time to get some answers from the King Wretch, and tells his friends to get out of the cart. Jack stands and calls to the King Wretch to get him, and the cart starts sliding down the tracks. Jack thinks everything is going well until the King Wretch grabs him with his talons, carrying him away.

Jack is dropped and finds the King Wretch inside the comic store, guarded by dozens of winged wretches outside. The winged wretches would normally attack, but instead they just stare at Jack as he goes inside. Jack demands to know what the King Wretch wants from him. In response, the King Wretch’s stomach opens into a portal. Within the portal is Ŗeżżőcħ, who speaks to Jack directly. He tells Jack that he is the one who gave him the visions, and that both outcomes are possible depending on what Jack decides.

Ŗeżżőcħ explains that he intends to enter this world and live in it, but he needs Jack’s help to accomplish this. He tells Jack that he admires his inner strength and that Jack’s choice will mean the difference between a wonderful world in which he is king, and a world in which everything he loves is destroyed. Ŗeżżőcħ gives Jack one final nightmare, this time showing Jack alone in the future. All of Jack’s friends are reunited with their families, and Jack is left with Rover. He sees himself from the outside and feels a gut-wrenching loneliness.

Inside the comic store, Jack is surrounded by all his childhood heroes. They inspire him to stand strong and deny Ŗeżżőcħ’s demands. As a result, Ŗeżżőcħ becomes enraged and commands the King Wretch and all the winged wretches to destroy the town and everything in it, leaving Jack for last. Jack’s friends intervene to help him escape and inform him that they left the radio on the rollercoaster. The King Wretch flies away, headed for destruction. Together, Jack and his friends board Rover and make their way back to the Town Square to fight.

At the Town Square, monsters and wretches are already battling. Jack reminds everyone that monsters and humans work well together and orders them to work as a team. Jack and his friends battle wretches while the monsters do the same. Jack gets an idea to use the trophy from the monster-human Olympics to attack the King Wretch, and Quint uses a crossbow to fire it right into the King Wretch’s mouth. The King Wretch chokes and throws up the trophy, and Dirk attempts to lasso its leg. It works for a moment, but more power is needed. Several monsters join in to help tie the King Wretch down. Jack boards Rover, who is now equipped with armor made of scrap metal.

A double-splash page shows Jack and his team all attacking the King Wretch at once. The King Wretch screams and pulls, taking everyone who is holding a rope with it. The King Wretch manages to free itself, and then Jack and the King Wretch are face-to-face. Jack and Rover charge toward the King Wretch, and Rover grips the ropes in his teeth. He pulls the King Wretch like a kite and flings it into the junkyard, where the Scrapken emerges and consumes the King Wretch alive.

With the King Wretch defeated, Ŗeżżőcħ is gone for now, but Jack knows there is always a chance of his return. The battle is over and Jack thinks the best way to celebrate is to bring everyone, monsters included, to Funland. Afterward, Jack and his friends sit atop the roller coaster waiting for the broadcast. They stay up all night, until it finally comes through first thing in the morning. The broadcast states that a group of people is living and surviving in the Statue of Liberty in New York City. Jack and his friends sit in stunned silence, unsure how to feel or what to do next.
