Story
One day, Princess Peach, Mario, Luigi, Toadsworth and some Toads in the Mushroom Kingdom are invited to Pi'illo Island, where there is supposed to be a special power that makes people fall asleep. During the flight, a dark pillow falls on an airship and turns into a dark figure that defeats Mario. After defeating him, the airship malfunctions and crashes into the Pi'illo Blimport. However, it turns out that it was all just a dream of Luigi. The group makes their way to Pi'illo Castle, where they meet Starlow. Mario and Luigi go into a room where Peach and Toadsworth accidentally trigger a test platform that sends them to ancient Pi'illo ruins. Mario and Luigi follow them and eventually find Peach and Toadsworth, as well as a Pi'illo that later turns out to be Prince Dreambert. They find a gathering room where Luigi takes a nap on the pillow. After everyone gathers in the gathering room, a dream portal opens a portal to the dream world. The dark figure from Luigi's dream drags Princess Peach into the dream world. After Mario chases Peach into Dreamy Pi'illo Castle with the help of a dreamy version of Broque Monsieur, he meets Dreamy Luigi, Luigi's dream character, who helps Mario with his wanderings in the dream world.
