Invincibility Bell

The Invincibility Bell is a power-up based on the Super Bell that appears in both campaigns of Super Mario 3D World + Bowser's Fury. It and its resulting form, White Cat Mario, can only be obtained if the player scans the Cat Mario or Cat Peach amiibo that launched with the release of the game, with the Cat Mario amiibo always producing an Invincibility Bell when scanned and the Cat Peach amiibo having a chance to produce it among other power-ups.

Similarly to the Invincibility Leaf, the Invincibility Bell grants a character the abilities of Cat Mario when obtained, as well as permanent invincibility to most enemies and objects as with the Super Star. When the Invincibility Bell is sent to the inventory, it will turn into a Super Bell, and after completing a level in Super Mario 3D World, its effect will go away and Mario will revert to the basic Cat form. The player will need to use the amiibo once again if they want to use White Cat Mario in another level.
