White Raccoon Mario is one of Mario's Power-Ups, and an upgraded form of Raccoon Mario. It first appeared in the canon game New Super Mario Bros. 2. It is accessed by the incredibly rare Invincibility Leaf.
In this form, Mario has all of Mario's Raccoon Suit powers with the addition of infinite invincibility, faster p-meter charge, and the ability to walk on water. The drawback is that Mario will be power-downed once he completed the level, plus that it only appears when Mario lost five lives in a row in the same level.
