Princess Peach must save the play as she takes the spotlight in her very own action game Princess Peach and some loyal Toads are about to enjoy a performance at the Sparkle Theater when the wicked Grape and the Sour Bunch bust on the scene to flip the script! These bad actors kidnap the stars of each play, terrorize the other cast and crew, and leave Peach trapped inside as they steal the show. To curtain-call this tragedy, Peach must team up with the theater's guardian, Stella. Using the power of Sparkle, Peach must take the stage of each play inside the Sparkle Theater and transform to match the performance. Each transformation changes up the action and comes with its own abilities for Peach to use against Grape’s evil acting troupe. Only by clearing all the floors and rescuing the star actors can she truly save the theater!
