Start a fire

Unimaginable warmth is nice, but you were looking for something more along the lines of unbelievable warmth. You quickly search the area for things to burn, and come up with a sizeable pile of wood, paper, puppy bits, and gasoline. Your pile of flammable stuff complete, you fish a lighter out of your backpack and light it all up.

You enjoy your even warmer warmth, at least until you are overcome by smoke and burned alive. That part is a little less pleasant.
