Karak was the mascot for the 2006 Commonwealth Games. He was modelled on a Red-tailed Black Cockatoo, a threatened species within the host country, Australia. Despite his initial acceptance by Australians, particularly children, and despite appearing on a lot of the foreign made merchandise, Karak was noticeably absent from the Games, particularly the Opening and Closing Ceremonies, where he was inexplicably replaced by a white duck.
Note : Borobi the blue koala has been announced as the official mascot for the 2018 Gold Coast Commonwealth Games.
