So B: Flesh Mites Enemy Pack

Crawling and burrowing through the fleshy tunnels in the Belly of the Beast, these oversized, armored parasites feed on the remains of undigested intruders. They have evolved thick, interlocking, chitinous shells which make them immune to most acids and explosives, allowing them to burrow deep into the intestinal track of the beast in search of food to scavenge. Though not particularly intelligent, the hungrier a Flesh Mite gets, the more vicious it becomes, sniffing the air with its face tentacles until it finds the scent of its next meal!
