I have an idea (mostly typed up in the sandbox) for a jar or some other vessel that basically floods an area with mist, making everything cold and damp. And, since that by itself isn't really thriller material, I added in an idea for a fog-based monster that sucks the heat out of anything it touches. Is what I have good? If not, why not? If yes, what more can I add to it?
