1-Up Mushrooms are a type of Mushroom that are very common in the Mario series. It will give Mario an extra life if he grabs it. There are various ways to get 1-Up Mushrooms, mostly from ? Blocks or Hidden Blocks. Jumping on six Para-Beetles in a row will also get Mario a 1-Up Mushroom.
This mushroom gives to the "player" a extra life (1UP).
Despite the Wii U/3DS title lacking any sort of life-system, 1-Up Mushrooms still appear scattered within the 10+ worlds, where their new purpose is to completely refill the player's health gauge.
1-Up Mushrooms reprise their role from the original Super Mario Bros. trilogy in this game, adding one life to the plumbers' total.
