Fly Guy

Fly Guys are enemies in Super Mario 64. They appear in Rainbow Ride, Shifting Sand Land, Snowman's Land, Tall, Tall Mountain, and Tiny-Huge Island. They are Shy Guys with propellers on their head.

Behavior
Fly Guys will either swoop down and attack Mario, or they will spit small flames that will follow Mario around for a while. When Mario jumps on a Fly Guy, he gains an extra jump boost, and when it expires, he begins spinning with his arms stretched out, slowly descending.

Landing
Some reports mention that Fly Guys have the ability to land on the ground and chase Mario on foot. Not much is known about this behavior and these claims are not verified.
