Bodies of malformed creatures lay torn apart, burned into blackened ruins, and bludgeoned to pulp. Blood froze on the walls, floor, and ceiling in a multicolored cascade from various experimental creatures. Large ice sickles formed from the blood above into multicolored stalagmites. Tracks in the bloody ice led to the various safe havens the monsters established in the hospital. Once routed the beasts fled and hid in their various hidey holes.
Despite their size power and adaption to winter aura not a one of them had more than a spoon full of brains between them. The monsters were large, ferocious, and highly adaptive. They were used to being the most powerful creatures around and when routed base instincts took hold.
