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 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 64 and 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.
