Mini Mario (form)

Mini Mario is a form that Mario and Luigi can become in New Super Mario Bros. and New Super Mario Bros. Wii. In the latter game, the two Toads (Blue Toad and Yellow Toad) are capable of becoming mini versions of themselves as well. This form allows them to jump higher, walk on water, jump on enemies without stomping them, and also fit through tiny Warp Pipes. The Mini form comes from when taking a Mini Mushroom. If damage is taken when in this form, rather than reverting back to regular-sized Mario, Mario loses a life.

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 will appear 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 will earn a coin every time Luigi is hit. However, every time Luigi is hit, he will lose 1 HP untill his current HP is 1, which no effect.

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 and is used for the same function.
