The Mushroom Kingdom has been a peaceful place thanks to the brave deeds of Mario and Luigi. The Mushroom Kingdom forms an entrance to the Mushroom World where all is not well. Bowser has sent his 7 children to make mischief as they please in the normally peaceful Mushroom World. They stole the royal magic wands from each country in the Mushroom World and used them to turn their kings into animals. Mario and Luigi must recover the royal magic wands from Bowser's 7 kids to return the kings to their true forms. "Goodbye and good luck!," said the Princess and Toad as Mario and Luigi set off on their journey deep into the Mushroom World.
