1-Up Mushroom

1-Up Mushrooms are green Mushrooms that give whoever eats one an Extra Life, and are usually the rarest one to be found. The 1-Up Mushrooms first appeared in Super Mario Bros. In the side-scrolling games, they move exactly like normal Mushrooms, but look different.

In Super Mario 64 and Super Mario 64 DS they were the most common Mushroom; though, they were not the only way to gain a life. Collecting fifty coins will also grant a life. These Mushrooms were the only type of Mushroom available in Super Mario Sunshine. The 1-Up Mushrooms appear smaller in this game. In Super Mario Galaxy, 1-Ups will give Mario or Luigi an extra life.

In Mario & Luigi: Superstar Saga and Mario & Luigi: Partners in Time, the 1-Up Mushroom revives Mario and Luigi with half of their HP if they run out and get knocked out. There is also a stronger variant called a 1-Up Super, which revives with all HP.

Although they do not appear as items in Mario Kart Wii, in the track Coconut Mall, there is a shop in a hidden shortcut that is selling 1-Up Mushrooms along with other classic Mario items.

A 1-Up Mushroom is also a space in the Nintendo Monopoly. It replaces the Income Tax space. When a player lands on this space, he or she has to pay either 10% or 200$.

Trivia

 * The instruction manual of Hotel Mario named the 1-Up Mushroom "Toad".
 * Ultra Shrooms from the Paper Mario series have a similar appearance as 1-Up Mushrooms, though they work entirely different. In some way, the Life Shroom replaces the 1-Up Mushroom in that series.
