HP-Up Heart Locations
In Paper Mario: Sticker Star, there aren't many stats in the traditional sense. This makes HP-Up Hearts that much more valuable, as it increases Mario's maximum HP by 5 points permanently. There are 16 in all, which brings a total of up to 80 extra hit points for Mario. For some of the bosses, Mario will need as many hit points as he can muster, especially if he's running out of stickers at the end of a boss fit.
