The scariest thing about this monster is its digestion ability. It doesn't have a mouth, and there's no distinction between a so-called head and body. It senses what's happening around it through vibrations, then anything that might be a living creature is immediately wrapped and engulfed into its body. The gray bodily fluid immediately starts working by extracting flesh from any possible gap — mouth, nose, or even pores — leaving behind only skeletal remains as the last trace of that life in the world, apart from becoming a constantly moving mist of flesh absorbed by the monster.
