Krawler -

Description from original post (created 2014-04-24 20:50):

This is an underground creature from the depths below bedrock, called the Krawler. It can never be exposed to light for it will be immediately disintegrate into ash, like the Vampire. It has many jaws on its stomach and hands, to chew up rocks when digging and rip apart the flesh of its victims. Its metallic-like spine, and armour like skin can deflect any rocks falling on it. It's 6 eyes can see from any distance, except for the sides like lizards. 

Yes, this is my comeback after a while. Not a very good one though.

Hope you like it.
