Mad Banzai Bill

Mad Banzai Bills are enemies in the game Super Princess Peach. They are obviously just angry Banzai Bills. Their normal, toothy glare is replaced by an even angrier expression, and are surrounded by fire. Even more dangerous than normal Banzai Bills, they fly incredibly fast. The cannons they are shot from are not seen, and they only appear in the levels that are unlockable only after defeating Bowser for the first time.

They are probably related to Mad Bullet Bills.
