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 sidescrolling games, they move exactly like normal Mushrooms, but look and act different.

In Super Mario 64 and Super Mario 64 DS they are the most common Mushroom; though, they are not the only way to gain a life, as collecting fifty coins also grants a life. These Mushrooms were the only type of Mushroom available in Super Mario Sunshine. The 1-Up Mushrooms appear smaller in this game.

The Paper Mario series featured a similarly looking Mushroom called Ultra Shrooms. Although it looked like a 1-Up Mushroom, they had a different effect as they were the best HP replenishing kind of Mushroom. The Life Shroom has a more similar effect and revive a character as soon as they get knocked out, altough the Life Shrooms don't look similar to 1-ups at all.

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. In Super Mario Galaxy, 1-Ups will give Mario or Luigi an extra life.

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. In Daisy Circuit there is also an advertisement for something called "1-Up Coffee".

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 play either 10% or 200$.

Trivia
The instruction manual of Hotel Mario named the 1-Up Mushroom "Toad".
