Frost Scrake is a monster from Killing Floor:Twisted Christmas. He also appears in the fake fan game FNAF:Twisted Christmas.
It is very silent and doesn't talk much. It can be assumed that it likes the cold. It only talks to friends or allies.
Frost Scrake activates on Night 2. It only appears in the East and West Halls. It will run down one of the those hallways. It will say the word "Frost..." before running down the hall.
*For some reason, both Frost Scrake and Foxy can run down the same hall at the same time, though it's very rare. It will still make you lose power.
