A Fly Guy is a type of Shy Guy that can fly using a propeller sticking out of its head. They first appeared in Super Mario World 2: Yoshi's Island. They are commonly found carrying items like Red Coins and even bombs. An egg can easily take it out. If eaten and spat back out it will become a regular Shy Guy. Another type of Fly Guy is the Leaf Guys, which are basically Fly Guys with leaves as their propellers. This variety appears only in Mario and Luigi: Bowser's Inside Story.
