The Mushroom Kingdom is having a celebration. It's nighttime, and Mario, Luigi, Peach, and Blue Toad are walking outside the castle during fireworks. They come across a clear pipe in the ground. The bros use their plumbing expertise to fix the pipe. Tons of items and blocks spew from the pipe. A green fairy-like person appears from the pipe. She is the Sprixie Princess and tells the four that Bowser has captured her people and put them in jars. Just then, Bowser appears and puts her in a jar, then returns through the pipe. Peach looks into the pipe and falls in. Mario, Luigi, and Blue Toad follow her.
