When I first saw the skrall head, it reminded me of this. I also made a facehugger and a horrible chestburster, but I took them apart before the pictures were taken.
About this creation
Ahhhh! He's gonna get you!!!
I was bored, and I had that head sitting around, being useless, so I figured, what the heck? And built this in about an hour. I was just trying out some lower chest designs, and I used a whopping 0 ball joints!!! (Which I have been using in a lot of my recent Mocs)
