Standing at an average of 12 or 13 feet, the Troll is a very dangerous but dense creature. They have unusually long arms, small, bald heads, and skin of a dull, granite gray color. Their legs are short and roughly as thick as tree trunks, their feet horny and flat. Harry describes it's smell as "a mix of old socks and the kind of public toilet no one seems to clean." They can be found carrying large, terribly carved wooden clubs. Their boogies are like lumpy gray glue.
