Mr. Squoo is the result of me messing around with the new version of Sculptris. I imagine that he could be either an alien creature that's "the head is the whole body," or he might be a handy alien head for you to plop on some other body.
Yes, there is a pretty heavy Protoss influence. I won't deny it.

Because the model details are sculpted in, the polygon count is somewhat high (though still quite a bit less than a million triangles).
