MAX UP Heart

HP-Up Hearts (known as HP Plus in Europe) are special hearts Mario can find during his adventure in Paper Mario: Sticker Star. As the name implies, these hearts will increase Mario's HP by 5 and will fully refill his health bar. It also increases his First Strike power. There are 16 of these to find and by collecting them all, Mario will have 100 HP by the end of the game.

 * Shy Guy Jungle
 * Head into the right exit from the main area with the piece of the Sticker Comet. Instead of whacking the big red flower, walk behind it and move to the right to find a secret hole in the wall. An HP-Up Heart waits inside.
 * Rumble Volcano
