Dunno if you guys have seen this toy or not.....
Might have been covered on the old boards, but I'll post it anyway, found it on google when looking for the ending shot Todd helped me out with. http://images.google.com/imgres?imgurl=http://thegalleryofmonstertoys.com/90swing/mcfarlanething2.jpg&imgrefurl=http://thegalleryofmonstertoys.com/90swing/mcfarlanething2.html&h=526&w=450&sz=64&hl=en&start=145&tbnid=VrRoqkdjb_oVhM:&tbnh=132&tbnw=113&prev=/images%3Fq%3Dthe%2Bthing%2Bmovie%26start%3D140%26ndsp%3D20%26svnum%3D10%26hl%3Den%26lr%3D%26safe%3Dactive%26sa%3DN

Not only do I have it, I also have a prototype of it and the spiderhead. A leg broke in transit on the spiderhead though... See them here: http://thething.ca/collection/toy_norriscreature_spiderhead_prototypes.jpg

I have never seen any The Thing toys... :( I have seen only pictures on different sites.
