White Tanooki Mario

White Tanooki Mario is a white lucent version of Tanooki Mario.

Super Mario 3D Land
In Super Mario 3D Land, when Mario loses five lives in a level, an Assist Block containing an Invincibility Leaf will appear. The block emits a tone to alert him of its presence. If Mario takes the Invincibility Leaf, he will become White Tanooki Mario, clad in a white and golden version of the Tanooki Suit. In this form, Mario is permanently invincible until he clears the level. After that, he reverts to regular Tanooki Mario. However, Mario will still lose a life if he falls into a bottomless pit, lava, or purple goo. Unlike in his invincible form, Mario cannot earn lives by defeating enemies. The player cannot obtain this form in levels he has already beaten or in any of the Special Worlds. Because of this, Luigi cannot obtain an Invincibility Leaf unless the player skips a level in a normal world (for example, by using a Warp Zone), or skips one of the optional "black ? block" levels in the first eight worlds.

New Super Mario Bros. 2
In New Super Mario Bros. 2, a transformation very similar to White Tanooki Mario known as White Raccoon Mario is present, except it is an invincible form of Raccoon Mario instead of Tanooki Mario.

Super Mario 3D World
White Tanooki Mario also appears in Super Mario 3D World. The Invincibility Leaf (referred to as the Invincible Super Leaf on the website) once again causes this transformation. Although the player still must lose five lives in a same course before the power up appears in single-player mode, the number of lives lost before it appears during multiplayer mode depends on the number of players (12 for two players, 18 for three, and 24 for four).

Puzzle & Dragons: Super Mario Bros. Edition
In Puzzle & Dragons: Super Mario Bros. Edition, if the player loses nine lives in one attempt at a course, Mario or Luigi will become White Tanooki Mario or White Kitsune Luigi, massively raising the team's attack power and increasing the amount of time needed to move Orbs around. However, the form only lasts for the current section of the level (Once all the enemies have been defeated, the leader reverts back to whatever form he was before.).
