A Refeshroom is a green mushroom with white stars that cures a condition known as Shroomshock. Toadsworth gets this condition in Mario and Luigi: Partners in Time, when Professor E.Gadd unveils his new time machine, and Mario has to go to Toadsworth's quarters to retrieve it. It is the only thing that cures Shroomshock. It has also appeared in Mario and Luigi: Bowser's Inside Story.
