The first of my Crypt blob commissions.
( http://www.furaffinity.net/view/5616248/ )

This one is a $10 crypt blob for  Mobiusnesbit . It's a highly caustic blob who can dissolve flesh and bone without problem, leaving only the souls of its victims (Living or dead) trapped within its ectoplasmic body to digest slowly over years, writhing in agony.

That's the species desc, anyway, as far as I know,  Mobiusnesbit's backstory will make him much friendlier than all that.
