Sure, based on the original title provided, here is a refined and simplified version: *Princess Peach™: Showtime! - US Version**

As Princess Peach is about to enjoy a performance at the Sparkle Theater alongside some loyal Toads, the wicked Grape and the Sour Bunch suddenly barge in to disrupt the show. These villainous actors kidnap the stars of each play, terrorize the cast and crew, and leave Peach trapped inside as they steal the spotlight. To curtail this theatrical tragedy, Peach must team up with the theater's guardian, Stella, and harness the power of Sparkle.

Using this magical energy, Peach must take the stage of each play within the Sparkle Theater and transform to match the performance. Each transformation grants her a distinct look and set of abilities to use against Grape's evil acting troupe. As Swordfighter Peach, she can slash and dodge attacks with precision; as Patissiere Peach, she can whip up tasty treats and decorate cakes with impressive speed; as Cowgirl Peach, she can wrangle foes with a lasso; and as Mighty Peach, she can hurl buses and slam enemies with super strength.

By clearing all the floors and rescuing the star actors, Peach can truly save the Sparkle Theater. Players can collect in-game coins to unlock additional colors and patterns for Peach and Stella, and can find hidden Sparkle Gems within the plays to earn action photos of Peach in her various transformations.

For an added challenge, players can test their mettle in Action Rehearsal plays, where they must survive waves of enemies. Equipping the Heart Charm can also give Peach a few extra hearts to aid her in her quest.

Through her transformative abilities and steadfast determination, Princess Peach must take center stage and put on the performance of a lifetime to thwart Grape's nefarious plans and rescue the Sparkle Theater. With the help of her loyal companion Stella and the power of Sparkle, Peach is ready to shine in her very own action-packed adventure.
