Mini Mario (form)

Mini Mario is a form that Mario takes upon eating a Mini Mushroom. Occasionally, this transformation may also be brought about by using a Poison Mushroom, or other various items. In New Super Mario Bros. Wii, the two Toads (Blue Toad and Yellow Toad) are capable of becoming mini versions of themselves as well.

The Super Mario Bros. Super Show!
In the animated episode "Princess, I Shrunk the Mario Brothers," Toad accidentally uses a shrinking potion intended for use on King Koopa on Mario and Luigi.

Additionally, in the live-action segment "All Steamed Up," Mario enters the Steam-O-Matic to make sure that it has been fully repaired. However, Sgt. Slaughter then shows up and turns the machine on at full power. Mario is eventually able to escape, but is shrunk due to prolonged exposure to the steam.

Mario Kart series
In the Mario Kart series, there is an item called the Thunderbolt, which shrinks every player except the user to a miniature size. Other sources of electricity may also do this to the player. In addition, an item from Mario Kart Arcade GP and Mario Kart Wii called the Thunder Cloud shrinks whomever it is floating over after a while. Super Mario Kart also features the Poison Mushroom, which can only be used by Peach and Toad when controlled by computers; they shrink any player that runs into them. In Super Mario Kart, Mario Kart 64, and Mario Kart 7, players who are shrunk can be temporarily flattened by normal size players. In the other games in the series, the effect is changed to simply being easier to push around.

Donkey Kong (Game Boy)
In Donkey Kong, when Mario touches a Poison Mushroom, he shrinks in size. However, this hinders Mario instead of helping him, and thus cannot be considered a powered-up form.

Mario Party series
Several minigames throughout the Mario Party series feature Mario and company shrunk to a small size.

Mario Party 4
Mario Party 4 debuts the Mini Mushroom, and is thus the introduction of Mini Mario as a power-up form. While in his or her mini form, the player can only roll a 1-5. There is also another item that can transform the player into their mini form: the Super Mini Mushroom, which allows the player to roll two 1-5 dice blocks. Players who miniaturize themselves can also go through Gates and play Mini Mini-Games.

Mario Party 8
In Mario Party 8, there is a candy called the Weeglee Candy, which transforms the player into three miniature versions of themselves. While in this form, the player steals a piece of candy from any opponent he or she passes.

Mario Party DS
In Mario Party DS, Bowser tricks Mario and his friends into coming over to his house for an apology feast, which ends with him trapping them in a cage and shrinking them with his Minimizer.

Mario Pinball Land
In Mario Pinball Land, Mario can buy a Mini Mushroom for ten coins. While mini, Mario can get into entrances like beehives and igloos that are normally too small for him to earn more Power Stars.

Mario & Luigi series
In Mario & Luigi: Superstar Saga, Mini-Mario is a Bros. Action taught to Luigi in Chateau de Chucklehuck. It involves Luigi standing behind Mario and hitting him with a hammer. Mario then shrinks to about half of his normal size, allowing him to fit through gaps normally inaccessible. In addition, when Mario is in Beanbean Castle Town, a small exclamation mark will appear over his head whenever he draws near an area of ground where a Beanstone is located. If the game is being played on the Game Boy Player, the controller will react. A larger exclamation mark appears if Mario is directly above a Beanstone. In order for him to be restored to his normal size, Mario must either be hit by Luigi's hammer or enter battle. If Luigi attempts to High Jump onto Mini-Mario, and if Mario jumps when Luigi is directly above him, he earns a coin every time Luigi is hit. However, every time Luigi is hit, he loses 1 HP; if his HP is at 1 when Mario jumps on him, nothing happens.

In Mario & Luigi Partners in Time, Baby Mario and Baby Luigi are small enough to go through holes the Mario brothers cannot fit in, which are about the same size as the ones Mini-Mario can go through. Also, the Bros. Ball move makes Mario and Luigi small enough to head through passages the babies can't fit into normally.

In Mario & Luigi: Bowser's Inside Story, once Mario and Luigi obtain the hammers, Luigi can hammer Mario to shrink him down to a small size just like in Superstar Saga. This ability is used for the same reasons as in the previous game.

New Super Mario Bros.
In New Super Mario Bros., Mario once again becomes Mini Mario by eating a Mini Mushroom. While in this form, the player can to jump higher, walk on water, jump on enemies without stomping them, and also fit through tiny Warp Pipes. Additionally, enemies that Mario can defeat with a stomp at regular height take a Ground Pound to defeat while he is Mini Mario. If damage is taken when in this form, rather than reverting back to regular-sized Mario, Mario loses a life.

New Super Mario Bros. Wii
The mini form also appears in New Super Mario Bros. Wii, retaining the effects from the previous game.

New Super Mario Bros. 2
The mini form will reappear in New Super Mario Bros. 2, along with the Mini Mushroom having the effects from the previous games.

Super Paper Mario
In Super Paper Mario, the Pixl Dottie has the ability to shrink the four heroes to a tiny size, allowing them to fit into small doors and through small holes in walls. Additionally, enemies cannot see the player while they are shrunk, but this does not stop enemies from damaging them. Additionally, while Princess Peach is asleep in Chapter 7-3, feeding her a Blue Apple results in her shrinking to a small size.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, the Poison Mushroom has the ability to shrink whomever touches it, making them weaker and easier to KO. The Thunderbolt item also appears, having the same effect as it does in the Mario Kart series.

Mario & Sonic at the Olympic Winter Games
In the DS version of Mario & Sonic at the Olympic Winter Games, Mini Mushrooms appear in Polastraits, Icepeak, and Blizland. As Mini Mario, Mario is able to cross thin ice, as well as narrow spaces. While Mario can become Mini Mario, Sonic cannot.

Mario Sports Mix
In Mario Sports Mix, Mini Mushrooms reappear as items. While mini, the player cannot carry a basketball, hockey puck, or dodgeball. They also have the inability to spike in volleyball, or preform a defensive maneuver in dodgeball.
