Refreshroom

A Refreshroom is a special type of Mushroom found in Mario & Luigi: Partners in Time and Mario & Luigi: Bowser's Inside Story. In the former game, this unique item cures "shroomshock," a state of unconsciousness. Mario has to find a Refreshroom for Toadsworth, who fainted during the unveiling ceremony of Professor E. Gadd's Time Machine. The plumber finds the mushroom in Toadsworth's room in Peach's Castle.

A Refreshroom reappears in Mario & Luigi: Bowser's Inside Story, during Giant Boss Battles. During these battles, Bowser can use a Refreshroom to restore 50% HP.

Trivia

 * Refreshroom is a portmanteau of "refresh" and "mushroom."
