Well, It's not much, but I filmed the coffin guy with my phone.
This gives you a small idea of what he looks like. See my previous post for a picture of him. This video just shows what he can do (in less than stellar video detail). I added a color tone to hide how crappy the video quality is. Believe it or not, this is an improvement.
His eyes light up (you can't really see it in this daytime footage) and he makes a moaning sound (which you couldn't hear so I added the music).
