Don't remember much about it, but I know it aired on CBC. Possibly a TV movie. Plotwise I think there was a greyish green creature attacking people ( called a Mole Waggott?) And I remember one of the cast dressed up as the creature (or maybe was the creature all along)and then he was chased around... Its been driving me crazy. Its not the swamp thing. I've checked. Any light anyone could shed on this would be awesome!!
