Rotten Mush

A Rotten Mush is a Mushroom rewarded to Mario in Super Mario RPG: Legend of the Seven Stars. This item is a rotted mushroom that only recovers five HP to an ally. One is given to Mario by either Grate Guy or Knife Guy when playing their respective games. Strangely, the item cannot be used in battle.
