Guys you have been totally fantastic with all the names and comments
I have slimed it up some more so hopefully that should help. Not sure if it is too wet now, it was harder to get a picture of!
I like the Star slime suggestion but am unsure as I always saw it as more terrestrial based, I am leaning toward something like 'Putrescence heart' or 'Horror within'.
I do also really like Red Orc's 'Blasphe-mass', or maybe 'Dr X's Mother in law'...
Anyway what do you all think?
