Life Shrooms are items found throughout the Paper Mario series. Whenever Mario (or his partner in Paper Mario: The Thousand-Year Door) passes out during a battle, the Life Shroom will revive the character and return ten HP to them, temporarily replacing 1-Up Mushrooms. If both Mario and his partner lose all of their HP at the same time, they will both be recovered with ten HP, but only one Life Shroom will be used.
