Trapped!

You run to the sink just as the snake regains consciousness. It begins slithering towards you as you search desperately for the Mongrel. You cry out when there is nothing inside. You look up and notice something in the sink. A bloody corpse of a small rodent lie inside the sink. You grab it and throw it at the snake. The snake grabs it and begins to eat it. You run towards a door on the far side of the room. You burst through, tackling it. You are now in what appears to be a prison cell. Beside you is a chainsaw. You grab it and continue on. You try cutting through the metal, but it doesn't work. Suddenly, you hear a voice, an unfamiliar voice. "Have you come to rescue me?" the voice asks.
You look around and see a man on a cot. "The man says we're safe here now, but that unless we find a way out, we're stuck here forever," he continues. "Every eight days, a man walks in here and gives me some bread. Please help me!"
You look around, but you see nothing. "Okay," you say, "we are going to tear this room apart until we find something."
All you see in the room is two cots, a trash can, and a chamber pot. There are no doors or windows, just bars.
