Mini-Mario

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 inaccessable. 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.

Trivia

 * 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.
