Recovery Block

A Heart Block is a type of block in the video game Paper Mario: The Thousand-Year Door. There are multiple different ones scattered throughout the game, each one refilling all of Mario's heart power and flower power for a small price. The first block will be found at Shhwonk Fortress, where it will give a brief description about the blocks.

These blocks are usually, if not always, found right before a boss fight, and right when you enter a new area such as The Great Tree or Hooktail's Castle.
