Clara Cluck

Clara Cluck is a civilian living on the Timeless River in Kingdom Hearts II. She is one of the citizens working on the building of Disney Castle, and is a major opera singer, although her talent is questionable. She was never aware of the invading Heartless, and was plenty confused by such events as the Windows of Time and Pete chasing Pete. She is likely still alive somewhere in Disney Castle, although Sora never encounters her there.
