A Frostfang is the Ghouled version of a Frostcrawler. Frostfangs are a navy blue colour, with teal hands, crowns and teeth. They are used by many of Dr. Blakk's operatives. When transformed they look much like a Frostcrawler with a big mouth, but with navy blue fur, teal hands, teeth and horns, fur "horns", and a lighter blue body. This is C.C. favourite ghoul.
