Blue Bullet Bills are a type of Bullet Bill found in Super Mario Sunshine. They are only found in the final boss battle in the game, where Bowser Jr shot them out of a cannon, along with normal Bullet Bills. They could be defeated by either jumping on or squirting them with FLUDD. When defeated, they would drop a 1-up Mushroom or a Water Bottle.
