Exactly, I've seen the Alien3 assembly cut. I loved it, but that super facehugger was a normal size. It just had a slightly different design. Kenner's stupid product of their own imagination is bigger than a whole human body.
And it's not like I consider it part of the life-line that needs to be explained, I was just curious to see if anyone could imagine a way it would fit. (I'm repeating myself now...)
