Recovery Block

A Recovery Block (also known as a Heart Block) is a type of block in Paper Mario. There are multiple different ones scattered throughout the game, each one refilling all of Mario's HP and FP. The first block is found in Jr. Troopa's Playground near Goomba Road, where the game gives a description about the blocks.

Recovery Blocks returned in Paper Mario: The Thousand-Year Door, only now, it would cost Mario a few coins for the health benefit, indicated above the block. The first block will be found at Shhwonk Fortress, where it will again give a brief description about the blocks.

These blocks are usually, if not always, found right before a boss fight, and right when Mario enters a new area such as Mt. Rugged or Hooktail's Castle.

Also, in the Japanese version of Mario & Luigi: Superstar Saga, a similar block that heals all of the brothers' HP and Bros. Points appears in a few locations, such as the Beanbean Castle Sewers, Oho Oasis, and Teehee Valley.
