After nearly two decades of waiting, Princess Peach is finally getting another game of her own. The third game to feature Princess Peach as the only playable character, Princess Peach: Showtime! sends Peach and the Toads on a journey to the Sparkle Theater, only to find new villains, Grape and the Sour Bunch, have taken over. As Peach transforms into several different characters with the help of the theater's guardian Stella, she takes the stage to save the play from her ridiculous new foes.
