Super Mushroom

The Super Mushroom is a powerup that typically grants the character an extra hit. Some characters, like Mario, Luigi, and Wario, start off small, only growing to their full size after acquiring a Super Mushroom.

Every character except Sonic and Arthur uses this powerup. Sonic's equivalent is the 10 Rings power-up while Arthur gains his suit of Armor. Some characters have variations on the Super Mushroom, such as Wario using garlic, that accomplish the same thing.

A variant of the Super Mushroom that appears rarely is modeled after the one from Super Mario Bros. 2. It must be picked up to be used, but it grants the character the effect of two Super Mushrooms, meaning one will be immediate and the other will be placed in the reserve item box unless it's already filled.
