Guided Bullet Bill

Guided Bullet Bills are a type of Bullet Bills that appear in Super Mario Sunshine. They only appear during the final battle where they are fired from Bowser Jr.'s ship, and upon descending on Mario's level start chasing him if they spot him. At first only two are fired, but as Bowser's bathtub is damaged, eight is fired at once.

Guided Bullet Bills come in black and blue varieties. The black ones have the same appearance as the normal Bullet Bills in Super Mario Sunshine, but as the final battle progresses their noses blink like Purple Bullet Bills. The blue ones are shot rarely and one at a time, their noses do not blink, and will let out a 1-Up Mushroom or a Water Bottle if stomped on.

There are inconsistencies regarding how the Guided Bullet Bills are classified. The known Japanese sources acknowledge the blue variant but not the black one, contrary to some English sources where both colors are listed as a same type of Bullet Bill. While most of them generally agree that they are a Bullet Bill variant, the official strategy guide by Prima Games calls them special Purple Bullet Bills which describes their behavior more than their color. The same guide has a similar case with Huge Red Electrokoopa in spite of its green shell.
