Cold N' Icy Dragon, Chilly Willy is an icy blue dragon with a long neck and a comparatively tiny body and is the boss of the Ice Side of Hailfire Peaks. He lives inside an icy lake at the top of the Icy Side mountain. This dragon is the sibling of Chilli Billi, the boss of the Fire Side. Similarly, he has a big head and small body like his brother. He wants a 12-foot anchovy deluxe pizza, but when he is defeated, he changes his mind and goes off to the fly-through McJiggy's.
