A while back I sculpted this little beasty in an attemt to see if I could sculpt something like the creature from The Thing. The sculpt isn't quite that gruesome, but it does have a certain "yuck appeal" about it. This miniature was just released by 15mm.co.uk under their SHM miniatures line.
Sculpted with 15mm in mind, there is no reason this creature couldn't appear on 28mm tables as well. It doesn't even need to be scifi or horror as this creature is in line with all manner of slimes and other dungeon nasties found in fantasy settings.
