Wilt Shroom

The Wilt Shroom is a Mushroom that appears in Super Mario RPG: Legend of the Seven Stars. It is a dried-up mushroom that has become weak due to lack of water. It recovers 10 HP to an ally. It is given to Mario by either Grate Guy or Knife Guy as a reward when playing their respective games.

Its successor is the very similar Dried Shroom (which has the same Japanese name as the Wilt Shroom) in the Paper Mario series.
