I had the green monster stretch creature. I wanted stretch armstrong but it was sold out and my parents found the monster one. I was watching Pawn Stars and a guy came in with just the head and got a lot of money for it. If he had the head on the original body he could have gotten $25K for it. I think I cut mine open just to see what was inside him.
EXACT same experience! I had the green alien dude as well and I got bored on a ca trip and cut him open and all the gooey shit poured out.
