Cluckoid
From Sonic Retro
The Cluckoid, called Kekko (ケッコー) in the Japanese Manual, is a rooster badnik from Sonic & Knuckles found in Mushroom Hill Zone. They are found standing in windvanes and, when approached, they inhale deeply, then release a gust of wind, usually blowing the player into obstacles. "Kekko" is Japanese for cluck.
