Moonkin: Wildmoon (Warcraft Premium Series 4)

Moonkin are large, flightless, sapient bird-like humanoids native to the night elf areas in northern Kalimdor. Sometimes called an "owlbear", these large bipedal creatures have the size of an upright walking bear, but with bird-like features such as a beak, feathers, and flightless wings. They also drop eggs of various sorts. They are related to the Wildkin. All druids must fight a moonkin named Lunaclaw in order to earn their Bear Form, and if they choose a seventh tier talent in the Balance tree druids can assume Moonkin Form themselves, a form nicknamed "Boomkin".
