The Sprixie Homeworld is a planet whose main landmark is the Sprixie Kingdom. It is similar in size and climate to Earth and the Mushroom World. As its name implies, it is where the Sprixie species originates from. Bowser and his forces invade the planet at the start of the game, and the Sprixie Princesses are caught in the aftermath. Mario and his friends quit their walk to stop the Koopa King before his plans to take over the kingdom (and possibly the planet itself) get too far. It can also be seen in the background of World 9.
