The slithering creations then attack Walgate's home, where most of the film's principal characters have gathered to discuss the crisis. Some of the brains get inside by breaking through a boarded-up window using their tendrils, while others leap to the roof and slither down through the fireplace's open flue. Some of the defenders are attacked and killed, but well-aimed .45 semi-automatic pistol shots to the brains soon make short work of most of the attacking creatures; they gorily bleed out as they expire. Professor Walgate exits his home as a diversion, but is quickly attacked and killed by his creation. Meanwhile, Major Cummings escapes out the back way and quickly heads to the airbase, where he saves the day by blowing up the radar installation's power machinery. This immediately robs the surviving brains of their high-energy food source, and the creatures quickly die, dissolving into puddles of goo.
