Morty's hand still trembled after pressing the button to destroy the demon-possessed family clones. The adventure, filled with bloodshed and betrayal, had completely shattered his fantasy of "interstellar exploration." He shouted angrily at Rick: "I've had enough! Adventures aren't supposed to be like this—they should be simple and fun." Faced with his grandson's resolve, the ever-arrogant Rick made a rare compromise—he proposed a bet: let Morty take full charge of the next adventure. If he succeeded, Morty would get to decide one out of every ten future adventures; if he gave up halfway, he'd never be allowed to complain about the cruelty of their expeditions again.
As the bet was sealed, the rest of the Smith family gathered around Rick, asking for favors. Beth wanted to become "a more complete woman," Summer longed to be popular at school, and Jerry hoped to shave two strokes off his golf game. Determined not to let these trivial matters interfere with their adventure, Rick pulled out a box emblazoned with a blue smiley face—the "Mr. Meeseeks Caller." He explained that pressing the button would summon blue Mr. Meeseeks, whose sole purpose in existence was to complete the assigned task and vanish instantly once it was done. Before leaving, Rick repeatedly warned: "Break the task down into simple goals. They're not gods."
Morty's adventure plan was straight out of a fairy tale: travel to a magical world floating among the clouds and help a poor village raise funds. Following the villagers' instructions, the two climbed up the stem of a giant plant to reach the Land of Giants. They hid under the dining table of a giant named Dale, waiting for the right moment—only to witness an absurd accident. As Dale stood up, he slipped and hit his head on the table corner, dying instantly. Dale's wife Rose and their son pushed open the door, saw the strangers cowering under the table, and immediately arrested Rick and Morty as murderers. In the giants' courtroom, they met a lawyer composed of a "microscopic race." Having suffered discrimination from the giants for years, the lawyer was determined to defend Rick and Morty as fellow "disadvantaged groups," ultimately proving their innocence with rigorous logic and securing their freedom.
Meanwhile, the Mr. Meeseeks at home were facing drastically different fates. Summer's Mr. Meeseeks delivered a passionate inspirational speech that earned her dozens of friends, then vanished gracefully after completing the task. Beth's Mr. Meeseeks acted as a "companion," going on dates with her, listening to her troubles, and helping her regain confidence with warm encouragement—also finishing his mission smoothly. Only Jerry's golf task hit a wall: no matter how the Mr. Meeseeks demonstrated grip techniques or analyzed swing angles, Jerry always found ridiculous ways to fail. Unable to complete the task and thus unable to disappear, the Mr. Meeseeks fell into a profound existential crisis. Trembling, he pressed the caller to request backup from his kind.
On their way back to the village after escaping the Land of Giants, Rick and Morty stopped to rest at a tavern called "The Thirsty Stair." The tavern was packed with all kinds of magical creatures, and among them, a flamboyantly dressed figure resembling a colorful jellybean—the "King Jellybean"—struck up a particularly friendly conversation with Morty. When Morty went to the bathroom alone, King Jellybean suddenly showed his vicious true colors and tried to assault him. Fear instantly unleashed Morty's potential; he grabbed the toilet seat and repeatedly bashed King Jellybean in the head, leaving the seemingly benevolent "leader" bruised and bloodied. Rick, who had been watching from outside the door, didn't ask for details when Morty stumbled out trembling—he just patted his grandson on the shoulder. Later, when the villagers appeared, cheering for their "beloved" King Jellybean, Rick didn't hesitate to draw his gun and shoot him dead—he never showed mercy to anyone who hurt Morty. In the end, the two used the winnings from a bet at the tavern to help the village escape poverty, and Morty's adventure came to a "successful" end.
The situation at home had spiraled completely out of control. Jerry was surrounded by hundreds of blue Mr. Meeseeks, who had gradually lost their sanity after failing to complete the task for so long. What started as patient guidance turned into frantic urging, then mutual accusations of ineffective methods, and finally a chaotic brawl. The blue creatures fought and bit each other in the living room, with white blood splattering everywhere. When Beth brought Jerry home, this was the apocalyptic scene that greeted them. Jerry snapped at the Mr. Meeseeks impatiently: "This is my golf game, not yours!" He then turned and walked into the room, leaving the group of blue creatures crumbling in despair.
During Jerry and Beth's date, the Mr. Meeseeks charged at Jerry with weapons in hand. Jerry immediately grabbed Beth and fled to the kitchen, where Beth suggested: "Simplify the task. Just try to hit a single standard shot first." Encouraged by Beth, Jerry took a deep breath, cleared his mind, and swung— the golf ball arced perfectly through the air and landed right next to the hole. With cheers of "Task completed!" all the Mr. Meeseeks instantly dissolved into blue sparkles and disappeared, leaving the living room finally at peace.
