Chapter 4: The Fate of All Universes
When Mario got there, Peach shouted: "We're here!" Mario opened the door and entered. The new Dimension D looked purple and black, unlike last time. Dimentio appeared in the room where the crew was. "I had to go buy some more drinks," he said, not looking at his company. "It took me forever to…Whoa…Wait! You're here Mario?" Dimentio cast a spell on a robot in the room. He then got inside the robot. "This time Mario," Dimentio said. "I'll be the victor." "You need to win this bro," Luigi said. "All universes depend on you." Mario charged at Dimentio and his robot
Dimentio knocked Mario aside with his robot. "You'll never defeat me!" he cried. "Bowser," Mario said. "Use your shell to destroy Dimentio's robot." Bowser did just that. The spikes were enough to make the robot blow up. Dimentio fell out of it. "All right!" Dimentio shouted. "I am going to suck every last one of you in the Underwhere." Dimentio made a square that showed the Underwhere and had a tornado that sucked everything into it. Everything, except Dimentio, was being sucked in. "We're through," Bowser stated. Everyone sobbed, except Mario. "How powerful is that shell?" he asked Carrie. "It is the strongest koopa shell known," she replied. Mario took the golden shell from his hat and threw it at Dimentio. The sucking spell wore off and Dimentio died. This time, the crew saw him get sucked into the Underwhere.
Bowser put the remaining space helmet on Peach as Dimension D and its surroundings faded away. The crew got back on board the airship. "Let's go tell Pixleader we won," Mario suggested. Everyone nodded their head in agreement. Mario took off, with the help of Thoreau's navigating to reach the queen's home.
When the crew arrived at Queen Pixleader's Castle, Carrie, with her shell on her, rang the doorbell. Pixleader answered. "We have destroyed Dimension D," Mario said. Pixleader shouted out with glee. "You saved all universes, Mario," Pixleader stated. She gave everyone a medallion. "Now," Pixleader said. "As told in the story, all of you will have happiness for the rest of your lives. You get yours first, Thoreau, I am your long-lost fiancée, Lady Luckgiver." "Wait," Thoreau said, "You are the one?" "Yes," Luckgiver replied. "Today is the day we marry each other."
Thoreau floated to Luckgiver and they disappeared together and got married. Thoreau's dream had finally come true!
