MAX UP Heart

HP-Up Hearts (known as HP Plus in the British English version of Paper Mario: Sticker Star) are special hearts Mario can find during his adventure in Paper Mario: Sticker Star and Paper Mario: Color Splash.

Paper Mario: Sticker Star
In Paper Mario: Sticker Star, these hearts will increase Mario's maximum HP by 5 and will fully refill his health bar, functioning similarly to Heart Containers from The Legend of Zelda series. It also increases the attack power of his First Strike by one for every two collected. There are 16 HP-UP Hearts to find and by collecting them all, Mario will have a total amount of 100 HP.

Paper Mario: Color Splash
In Paper Mario: Color Splash, there are six of them and each time Mario and Huey collect a Big Paint Star, their maximum HP is increased by 25 and the power of the First Strike is increased as well. When all six are collected, Mario reaches a grand total of 200 HP.
