 Of all the items in the Mushroom Kingdom, the Power Stars are the most magical and powerful. These 120 stars power Princess Toadstool s castle. One day, the Princess invites Mario over for a cake-but while he s getting there, Bowser is invading! The King of the Koopas goes into Mushroom Castle and steals most of the power stars-the others are hidden by Peach and her Toad subjects. But alas-Bowser takes enough to not only create his own strange and twisted worlds from paintings in the castle, but to imprison Peach and her Toads in the castle walls themselves! But Bowser didn t count on one mustached plumber, whose mission is to recover the stolen stars and bring their power back!
