Princess Peach: Showtime Famitsu Strategy Guide Book

Completely supports Peach's transformation. Lots of information on actions and dresses!
Maps for all stages are posted, so the locations of glittering stones and ribbons are perfect.
Not only does it explain how to defeat bosses, but it also explains how to play Action Rehearsal in an easy-to-understand manner.
There is also a page that summarizes the story of this work, so it is convenient to look back on what kind of story it was!
