Marmaduke Coot is an anthropomorphic coot-parrot hybrid.
Maramduke Coot is a cousin of Donald Duck. Marmaduke is a lunatic and used to be a stage magician; and is an expert at technological tricks, having invented a broomstick that flies when it is cranked. Indeed, he is quite the inventor, and has built himself a sentient robotic butler, Robert. Marmaduke lives in Bad Manors, an impressive estate that used to be haunted until the real spooks were scared away by Marmaduke's illusions.
Behind the scenes
Cousin Marmaduke only ever appeared in the 1953 story Robert, the Robot.
