Cthulhu Fhtagn? Haha, that was my first reaction to this, actually. There are a lot of things it could be, but I sorta saw the things at the top as coral, and then some tentacled face beneath. It's rather interesting in that regard, that it's a little ambiguous.

Jeeze, I use that term too much.

I had to google that "Cthulhu Fhtagn".. it does look like it..
