Life Mushroom

The Life Mushroom is a special type of Mushroom that appeared in Super Mario Galaxy and Super Mario Galaxy 2.

Super Mario Galaxy
In Super Mario Galaxy, when Mario collects a Life Mushroom, the sections of his Health Meter will increase from 3 to 6. However, if he takes damage from enemies or other obstacles up to three times without collecting a coin to regain health, his Health Meter will revert back to just 3 sections of health.

Super Mario Galaxy 2
They reappear in Super Mario Galaxy 2 and behave just as they did in the prequel. However, they appear to be much more common in this game than in the first. Unlike in Super Mario Galaxy, the player will receive a 1-Up when they collect another Life Mushroom. However, this will only work if all six sections of the Health Meter are filled when Mario collects the second Life Mushroom. If they are not, then the second Life Mushroom will only refill the Health Meter back to six, instead of giving Mario a 1-Up. This feature was not included in the previous game.

Trivia

 * In either game, Life Mushrooms can be purchased from Luma Shops for thirty Star Bits on various planetoids. They will usually be positioned on the last planet or planetoid that is encountered before a large Boss battle.
 * Any Life Mushrooms collected will be ineffectual while playing under Daredevil Comet conditions.
