Peach's first solo adventure takes place on Vibe Island, where Bowser is holding Mario and Luigi captive in his castle. The Princess, armed with her trusty parasol, can harness the "emotional vibes" emitted by Vibe Island, using her mood swings to forge a path to Bowser's castle. You control the pink princess's emotions with the touch screen as she treks through eight areas on her quest to retrieve the magical Vibe Wand and, ultimately, the Mario brothers.
