Super Shroom Shake
From the Super Mario Wiki
A Super Shroom Shake is an item found in Super Paper Mario, that replenishes twenty HP and cures poison. They are for sale in Notso's shop at Flopside. They can be used for three recipes in the game. It replaced the normal Super Shroom as the basic recovery item, because Super Shrooms are only found in some blocks, and recover twenty HP the moment they are touched.
