The Powerup Cancellificatinizer is an item that, upon being triggered, cancels all other powerups currently in effect. This includes "whole race" powerups as well, but not items. This item can also cut the Mutant Tail Thing. This is a good item to use when an annoying powerup is in effect, such as Bouncy Bouncy; but the player must make sure they are not going to cancel good powerups that are also active at the moment.
