Yes, the big maggot from Half-Life. This adorable monster.

I'm stuck on what to put in their TC, or what their Minion should be, especially since Cranial Crustacean unfortunately isn't a minion. (Which would have helped Zombine and Fast Zombie too. xD)

You could do an overlay for the minion, though. Get it all custom and stuff. ;]

There a few machine-ish looking minions in the Atebus shop, could probably work out for the TC if nothing else.
