MAX UP Heart

MAX UP Hearts (formerly known as HP-Up Hearts, and 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, Paper Mario: Color Splash, and Paper Mario: The Origami King.

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, Mario obtains an HP-Up Heart each time he collects a Big Paint Star, which increases his maximum HP by 25 as well as the power of his First Strike. When all six are collected, Mario reaches a grand total of 200 HP.

Paper Mario: The Origami King
HP-Up Hearts return in Paper Mario: The Origami King under their current name. Like in Sticker Star, they can now be found around the world in various locations. Each one increases Mario's maximum HP by five, ten, or twenty. Collecting hearts also increases the amount of damage Mario's attacks and First Strike do. Collecting all hearts raises Mario's HP to a maximum of 200 (not counting HP boosts from Heart Plus accessories). The Love Toad, who Mario rescues in Shogun Studios, returns to Toad Town, and can tell him of the locations of any Max Up Hearts that were missed.
