From the Super Mario Wiki
A Heart Container is an item in The Legend of Zelda series, also used in the Super Smash Bros. series. In Super Smash Bros., Heart Containers healed all damage, returning the player's damage level to 0%. In Super Smash Bros. Melee, they were toned down a bit, instead healing 100% points of damage. However, the three Heart Containers seen in the All-Star mode still healed all percent of damage. Heart Containers reappear in Super Smash Bros. Brawl, with a new appearance taken from The Legend of Zelda: Twilight Princess. They continue to restore 100% points of damage and as in Melee, there are 3 of them in the rest area of All-Star mode, which each heal all damage rather than the 100% in any other game mode.
Heart Containers drift to the ground slowly. In the first two games, they cannot be picked up until they touch the ground. In Super Smash Bros. Brawl, they can be grabbed in mid-air.
