Figure One: Snek Belly.... It was hard to photo. At this point he started squirming....
Figure Two: Full body under good light.
Here's a close up:
It looks far too similar to a spider, but the color resembles that of the phantom spider, which is why I made that assumption.
And finally... The photo that made Wheatley hate me because I put on the flash.....
The face markings is very suggestively spider morph.
And then considering the fact that he has a bit of a wobble, which is exclusive to spiders from what I understand.
