Fawfulcopter

Fawfulcopters are UFO-like enemies that appear in Mario & Luigi: Bowser's Inside Story. They resemble Fawful, and they have one top section with Fawful eyes and a saucer bottom. Sometimes, a mouth comes out of the bottom on a rod and talks to Bowser. Bowser can inhale them, and Mario and Luigi can fight them. In the place of an attack, they flash a red light, which summons more enemies when fighting with Bowser unless he inhales them, which effectively disables that function.

Fawfulcopters also appear during cutscenes when Bowser is being controlled. They mainly serve as messengers for Fawful when he is not present. They also appear in Princess Peach's Castle and hold keys which open certain doors in the castle.
