Okay...

I see what you are talking about.

I would suggest taking him to the vet. You will need an x-ray, and see what part of his body is broken, as it is obvious that there will be some...

The bruising will go away, but... the disfigurement may subside, but never go away. I've never had something that bad before, but I've had animals lodge themselves into things, and come out fine..

So... My suggestion is to take him to the vet and get an idea. Doesn't have to be emergency, but a vet none the less.
