Actually, it was a maggot in Satan's nose


Watch it again, it's the tail of the serpent!

I'm telling ya, it's a maggot. One way to tell is that you see the "head" of it come out, curl up, and go back in, followed by the maggot's "tail." The other way, and a much more definite proof is Mel mentioned it in a ninterview when asked about the creepiness of the Satan character in the film. :)
