Super Mushroom

A Super Mushroom is a red Mushroom that allows whoever eats it to grow to an enormous size. When hit by an enemy, the consumer shrinks back to his normal size instead of losing a life.

The Super Mushroom appears in Hotel Mario. It doesnt make Mario big or small, but gives Mario the chance to take one hit and not lose a life. The only difference between the normal Mario and the one that ate the Super Mushroom is strange coloured overalls.

In relation to Mario Kart, a Super Mushroom is an item that gives the kart continuous bursts of speed over a time period of around eight seconds. A particular Super Mushroom is known as the Golden Mushroom can be used over and over. In some games and tracks, it is necessary to clear some (optional) jumps. Hitting another player during the boost allows players to steal any items in some games, or a balloon in Battle Mode's Balloon Battle the other kart may be carrying (in Mario Kart Double Dash!!, if both characters have something, then the player will steal the back player's item and have the front one drop their item).

In Mario & Luigi: Superstar Saga, Super Mushrooms restore 50 HP to whoever eats one. However, in the game's sequel Mario & Luigi: Partners in Time, a Super Mushroom only recovers 40 HP.

In Super Smash Bros. Melee, it allow the player to grow to an incredible size thus making him heavier and harder to knock off. Experiment with them in Huge Melee mode. Use one while playing as Mario, then do his stance. This will make him taller than almost all the levels in the game. The item will return in Super Smash Bros. Brawl, with the exact same effect.

In Super Mario Galaxy, the Super Mushroom restores Mario's health meter. This mushroom differs from the Super Mushroom from previous games. This mushroom is red with a star-shaped yellow spot.

Trophy Description in Super Smash Bros. Melee
''Super Mario Bros. veterans will recognize these power-ups, which hid inside brick blocks and helped Mario and Luigi withstand enemy attacks. In Super Smash Bros. Melee, they temporarily turn your character into a giant. Not only will your size and strength increase, but so will your mass, making it harder for foes to knock you off.''

Trivia

 * The manual of the original Super Mario Bros. actually refers to the Super Mushroom as the "Magic Mushroom".
