1 UP Heart

1-Up Hearts basically perform the same function as 1-Up Mushrooms, awarding one Extra Life to the player in Super Mario Land and its sequel, Super Mario Land 2: Six Golden Coins. Most likely, the reason 1-Up Hearts were used in these games rather than 1-Up Mushrooms was that the black-and-white palette of the original Game Boy would make it impossible to distinguish between 1-Up Mushrooms and Super Mushrooms.

Unlike most Mushrooms, in Super Mario Land, a 1-Up Heart will remain in one place until Mario grabs it. However, in Super Mario Land 2: Six Golden Coins, the 1-Up Heart moves like the 1-Up Mushroom and would slide away from Mario unless he could quickly catch it. Also in Super Mario Land 2, the 1-Up Hearts could be caught by Pumpkin Zone's witch boss, who would then run away from Mario with them.

1-Up Hearts appeared in minigames in both Super Mario Land titles, and similar items appeared in Game & Watch Gallery 4 minigames. These Hearts would replenish a life that was lost, and only appeared when a player reached 200, 500, and 700 points in most games; if a player did not have any Misses when they passed these points, a Heart did not appear. In this game, they were pink and had a two-toned color scheme similar to the one suggested by the white and grey pattern of the Super Mario Land 1-Up Hearts.
