A Recovery Block (also known as a Heart Block[citation needed] or an HP Block[1]) is a type of block seen in the Paper Mario and Mario & Luigi series of Mariorole-playing games. Recovery Blocks are commonly found in areas where a Save Block is present and before the player enters a boss area, and they fully restore the player's refillable stats when struck.
In Paper Mario, Recovery Blocks are transparent blocks with a sleeping red heart floating in the middle of each block. There are multiple different ones scattered throughout the game, each one refilling all of Mario's HP and FP when hit.
Paper Mario: The Thousand-Year Door
Recovery Blocks return in Paper Mario: The Thousand-Year Door, only now, it costs Mario a few coins for the health benefit, indicated above the block. The amount of coins required increases as one progresses through the game. Their design is very similar to that of their design in Paper Mario. These blocks are usually, if not always, found right before a boss fight, and right when Mario enters a new area such as Hooktail Castle.
Paper Mario: Sticker Star
Recovery Blocks reappear in Paper Mario: Sticker Star, though they only fully recover Mario's HP. They function the same way as they do in Paper Mario, allowing Mario to use them at any time for free.
Mario & Luigi series
Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
A few Recovery Blocks are found in Mario & Luigi: Partners in Time, though they are almost as scarce as in the Japanese version of Mario & Luigi: Superstar Saga. Their design in this game is that of a blue block with a magenta heart symbol in the middle of the block. There is one in Peach's Castle in the present, one inside Yoob's Belly, and one just before the throne room of Shroob Castle. As in Paper Mario, they are free to use.
Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
They make a return in Mario & Luigi: Paper Jam. They appear to be a rainbow-flashing rectangular block with a pink heart on it. Also in the game, they are more common. They are usually placed near locations where bosses are fought (like near the giant door to the summit of Mount Brrr which is where King Bob-omb is fought), and also in Toad Villages. If hit, the trio's HP and BP are both fully restored.
