So far, going to call this a Horrid. Based on a necro-synthetic shapechanging ooze as the main monster in the upcoming Rogue Moon adventure set on Circe's moon, not unlike The Thing or Invasion of the Body Snatchers. Now this isn't all my modeling, the giant monstrous mouth is, but I just deformed and duplicated parts on a Poser model to depict this very creepy thing... enjoy!
