A Sky Guy is a Shy Guy that floats using balloons, unlike the Fly Guys who use actual propellers. Their debut was Super Mario World 2: Yoshi's Island, where they caused major trouble for Yoshi by dropping hazardous objects such as crates and bombs. They reappeared in Paper Mario, where they shot at Mario using slingshots. Mario can pop the balloons and ground them, making them ordinary Shy Guys.
