Male Leaf Dragon
From Tardis Wiki, the free Doctor Who reference
A male Leaf Dragon appeared at Coal Hill Academy looking for his mate after she was imprinted on the body of Coach Dawson. This dragon killed a cleaner, the headteacher Mr Armitage, Assistant Coach Carroll and later on killed Coach Dawson himself, after he threatened to kill his mate. Ram Singh suggested that he make his skin into leather, "make a chair or something". (TV: The Coach with the Dragon Tattoo)
