Peach must save the Theets (the residents and actors) and the Sparkle Theater and various themed plays with the help of Stella, the guardian of the Sparkle Theater, and transformations Peach discovers in each area/play. It's been taken over by Grape, a masked villain, and her Sour Bunch, her acting troupe. In the demo she becomes Swordfighter Peach and Patissiere Peach (a pastry chef). The developer is Good-Feel, the makers of Kirby's Epic Yarn and Yoshi's Wooly World.
