Mushroom

Mushrooms are items which restore players' health. They appear in most of the RPGs. They are also items in the Mario Kart series.

Super Mario Bros. 2
Mushrooms add an additional mark/heart to the life meter, to a maximum of four. The meter then resets to two marks at the start of the following stage. Up to two are located in each stage, and are found only in specific Subspace locations within the stage. In Super Mario Advance, the extra mushroom is added for each level to make the total of five hearts.

The equivalent to the Mushrooms in Yume Kōjō: Doki Doki Panic are hearts.

Mario Kart series
In Mario Kart, a Mushroom is an item that grants a Kart a brief burst of speed when used. Mushrooms can come in singles or triplets, the latter providing three Mushrooms to use in a row. In Mario Kart: Double Dash!! a character holds these mushrooms in piles, but if the kart is hit by an item on the road, these mushrooms will fall off and the character will have one remaining on hand. Normally this set appears as default power-ups in time trial mode (excluding Super Mario Kart) to use specially over shortcuts of a determined course. Another type of Mushroom is the Golden Mushroom, that can be used indefinitely in a restricted period of time.

In recent Mario Kart games, Mushrooms can be used as well to knock aside other karts or even steal an item from the opponents when coming in contact as seen in Double Dash!!. In later games, this move is not possible to steal items, but works to steal balloons, Shine Sprites or Coins from other players when playing in Mario battle mode.

The Mushroom is also used as the logo for the Mushroom Cup in every Mario Kart game to date.

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, a basic Mushroom recovers 30 HP for one party member. This Mushroom had a red and white cap with an orange stem (and no face). The Mid Mushroom, as a result of also being more expensive, is that they recover 80 HP to one party member. Mid Mushrooms differ in appearance from the regular Mushroom, having a green cap than a red one. The Max Mushroom, being the greatest one of them all, is about to recover all HP to one party member. They have a yellow cap, different from all other Mushrooms. The bad Mushroom, only found in Seaside Town, does not recover HP and is used only in battle. When used, they poison an enemy of choice, but some enemies don't get poisoned, so it is not that useful. They have the same appearance as a regular Mushroom in the game. However, Mushrooms that are found in Treasure Boxes recovers all HP and FP for Mario's entire party. These Mushrooms are used as soon as they are picked up. Additionally, these powerful Mushrooms have faces. Also, most Mushroom Treasure Chests restock with every selection of a certain area. A special type of Mushroom is sold by the Goombette Triplets at the shop in Monstro Town. These Mushrooms, apart from restoring 30 HP, also turn the user into a Mushroom during battle.

A particular status ailment turns characters into a Mushroom. While a Mushroom, the character recovers health every turn, but is completely immobilized. Like the Mushrooms from the Treasure Chest, they also have faces on them.

Mario Party series
Mushrooms appear as items in the Mario Party series. The first time they appear is in Mario Party 2 (where they are Mario's favourite item), and they have reappeared in other Mario Party titles. In Mario Party 4, Mario Party DS, Mario Party 8, and Mario Party 9, the item is not present (although there are similar items, such as Mario Party 4s Mega Mushroom, and Mario Party 8s Twice Candy). They allow for two rolls of the Dice Block during one turn. If the two digits rolled are the same, the user will receive ten Coins. If players want to purchase this item, the price will usually be five Coins.

In Mario Party Advance, their effect is different. In this instalment, Mushrooms allow the player to roll the Dice Block. Each turn, a Mushroom will be depleted from the stock. For players to win Mushrooms, they have to win minigames. Players will usually receive three Mushrooms when they win a minigame, although there are cases in which the award for winning a minigame will be six Mushrooms. The game ends when the player doesn't have any Mushrooms left.

Mario & Luigi: Superstar Saga
Mushrooms are the basic item for healing in Mario & Luigi: Superstar Saga. They are the cheapest item found in stores and the first item obtained. Regular Mushrooms restore 25 HP, Super Mushrooms restore 50 HP, Ultra mushrooms restore 120 HP, and Max Mushrooms restore all HP. Five special Golden Mushrooms can also be found in the game; the rare item restores all HP and BP. Shroom Badges that can be purchased at certain shops will increase Mario and Luigi's attack according to the number of Mushrooms in their inventory.

A unique mushroom called the Invincishroom can be found only when the player has beaten the high score of a certain minigame. The player cannot use it, however, because Mario eats it as soon as he and Luigi win it, causing him to become very sick and slowly turn into a bean. Luigi cures Mario by giving him a certain plant, which is found in Guffawha Ruins.

Mario & Luigi: Partners in Time
Mushrooms act in the same manner as in Mario & Luigi: Superstar Saga; they restore HP for one member. While the Max Mushroom is still the same, the regular, Super and Ultra mushrooms heals 20HP, 40HP and 80HP respectively. In Mario & Luigi: Partners in Time, there are also items called Mushroom Drops, which will every single member on the team, very much like the Nuts in Mario and Luigi: Superstar Saga. Unlike Max Mushroom and Max Nuts, however, there is nothing more powerful than Ultra Drops. Shroom Badges make a return, but with a different effect: they now increase the healing effects of a Mushroom.

Shroobs, the main enemies in this game, bear a resemblance to Mushrooms. They have the same mushroom shape and spots, and they even live on a planet shaped like a mushroom.

Mario & Luigi: Bowser's Inside Story
Mushrooms return, but Mushroom Drops are replaced in favor of the original Mario & Luigi series Nuts. Mushrooms act in the same manner as in the two preceding games. Mushrooms in this game heal 30HP, Super Mushrooms heal 60HP, Ultra Mushrooms 120HP, and Max Mushrooms heal 240HP instead of all HP like in the previous installments.

Also, there was a Clothing item called the Mushroom Glove, which would have a random mushroom be consumed every turn to the bro. that has the glove. Bowser does not eat mushrooms unless:
 * A Goomba/Bob-omb from a Jailgoon, A Trashure or Dark Trashure or a Naplock gives it.
 * The Refreshrooms that recover half of Giant Bowser's Health Meter.

Paper Mario
In Paper Mario, mushrooms act like healing items, just like the other Mario RPG games. In this game, they heal 5 HP when used. Several variations of mushrooms could be found, such as the Volt Shroom or the Life Shroom. Recipes can also be made for other types of Mushrooms by combining certain ingredients together by Tayce T.

Paper Mario: The Thousand-Year Door
Mushrooms return in the Paper Mario sequel, Paper Mario: The Thousand-Year Door. They have the same manner in healing as in the prequel. Yet now that Mario's partners have HP, mushrooms can restore a partner's HP also. The many variations of Mushrooms from the prequel return, with the addition to the Slow Shroom. Small creatures named Punies commonly eat Mushrooms, shown by brother and sister Punio and Petuni. At the end of the game, Punio and Petuni give both Mario & Peach a Mushroom to enjoy on their boat ride home.

Super Paper Mario
Super Paper Mario is a platformer RPG game, so unlike in the preceding games, Mushrooms cannot be bought in shops. Instead, they are found out of ? Blocks and heal ten HP upon contact. They also give the player one thousand points. Replacing them is the Shroom Shake.

Trivia

 * In Mario & Luigi: Superstar Saga, it is interesting to note that the Mushrooms have no faces, and their cap's coloring is reversed. They have red spots on a white cap, making the Mushrooms look much like Toad or the Super Mushrooms from the NES version of Super Mario Bros. 3.
