The Invincibility Leaf is a power up in Super Mario 3D Land. It can only be obtained if you fail about five times on a level you have not completed before. When you get it, it will basically look like a silver or white Tanooki suit that sparkles. It will last throughout the whole level unlike normal invincibility power ups that only work for a small period of time. The Invincibility Leaf has all the same abilities as the normal Tanooki suit but also makes you invincible. The Invincibility Leaf can be used in all levels including on castles and in boss battles except for the last battle in world eight. Once you have completed a level, you will no longer be able to obtain it for that level.
