Super Mario 3D World

Whilst exploring the Mushroom Kingdom, Mario, Luigi, Princess Peach, and Toad come across a strange clear pipe, which a curious green fairy-like creature, called a Sprixie, pops out of. Suddenly, Bowser appears and captures the fairy before escaping through the pipe. Thus, Mario and friends enter the pipe to pursue Bowser, and find themselves in the strange new Sprixie Kingdom as they search for the Sprixie, along with some of her other companions.
