It looks like you and Cleon never reached an agreement on gnaw. I'm impartial on the matter. 

I was thinking improved grab and gnaw, actually, since it brings the victims to its mouth. But that's usually associated with a bite attack.
Aren't we getting away from the original monster a bit. It didn't grapple creatures around its own size, but snatched things off them. It seems to only be able to grab much smaller opponents/victims.
