Tanooki Suit

The Tanooki Suit is an item that grants Mario and Luigi the same abilities as the Super Leaf, but with an added bonus—the power to turn into a statue at will. This allows the user's presence to go unnoticed by enemies passing by for a short period of time, while also becoming temporarily invincible; though he cannot move while in this form, he can still time his attacks by transforming while in motion, already heading in a desired direction. This is used most efficiently by Luigi in his battle with Swampy during the Brawl in Boulder Canyon, as he shoots forward at the same time as the crocodile before becoming a statue, so that an attack is performed in which Swampy is brutally struck by the resolute form and sent flying backward as a result.
