Boktai - The Sun is in Your Hand: Solar Tree (Secret Room)

On New Game+, a warp appears at the Solar Tree which will take you to a room that informs you of your in-game information as well as what items, if any, you are missing. There are also two chests containing the Solar Leaves and Empty Gourds from your previous playthrough. At this point, my save is at 100%, so I have everything!
