Eating & Gib behavior

[CharliForms]

I notice that you're working on making the Barnacle eating animations more accurate, but I also notice a few missing eating animations for Bullsquids, zombies, and Alien grunts, all of which I've seen feast on bodies in official Half-Life titles. It would be cool to see this behavior replicated on this Gmod port, I've done a lot of experimenting and haven't seen it implemented in the Github or Steam releases.

Side note, I noticed that the gibs spawned by Xen ceiling turrets have their own Half-life quality sounds. I don't expect you to rework the gib system, but if these older noises on the ceiling turret were somehow applied to the gibs of other creatures, it would be a pretty nice touch. Hardly a big deal though.
