A Shroom Shake is an item found in Super Paper Mario. They replenish ten HP and cure poison and are a key ingredient in many foods. The only reason why it replaced the normal Mushroom as the basic recovery item is because Mushrooms are only found in some of the blocks, and recovered ten HP upon contact.
Shroom Shakes could be purchased at various stores or acquired upon defeating certain enemies. They could also be stolen from Mr. L or Shadoo, by having Thoreau grab a Shroom Shake whenever the opponent is about to drink one in battle.
