In Mushroom Battle, all battles are fought solo. Mushrooms and stars from the Mario series will appear regularly, causing different effects to any fighter that picks them up: * Super Mushroom: Increases the fighter's size by one level. * Mega Mushroom: Increases the fighter's size to its maximum. * Poison Mushroom: Decreases the fighter's size by one level and lowers his/her stamina sightly. * Golden Mushroom: Increases the fighter's speed for a fixed period of time. * Star: The fighter becomes invincible for a brief period of time, and causes guard damage to the opponent regardless of his/her size.
