Mushroom is a status ailment that only appears in Super Mario RPG: Legend of the Seven Stars
The Mushroom effect makes characters turn into a mushroom. The color of the mushroom depends on who is transformed (Mario is red, Peach is pink, Mallow is white/grey, Geno is blue, and Bowser is green).
Whenever someone is turned into a mushroom, they cannot act. Instead, they recover a certain amount of health each turn until they transform back. Many moves such as Petal Blast can inflict this ailment. Using the Trueform Pin and Safety Badge will protect from this ailment.
