Small heart

A Small Heart is an item found in Super Mario Bros. 2. It would fly out every time eight enemies are killed. When Mario, Luigi, Princess Toadstool or Toad grabs it, they replenish an empty slot in their Health Meter. They have somewhat the same function as a Mushroom in this game, with two exceptions: Mushrooms both extend and fully replenish the health meter, while small hearts cannot.

In the Game Boy Advance version, Super Mario Advance, they are much more common, and are renamed Hearts, being larger and appearing when a thrown object takes out two enemies in a row. They also appear from enemies defeated by Shells, and from Mega Guys and Giant Ninjis when they are thrown to the ground or beaten. They are also found floating in midair (even in boss arenas) and under grass, referred to as Heart Radishes.

It also appears in Dance Dance Revolution: Mario Mix. When used, it will refill half of Mario or Luigi's dance meter if it empties. It can be bought at any shop in Story Mode for seventy coins.
