kitakaze - Sorry I missed your question before about what it would take to build "Patty." When I finally get around to making a video on the subject I'll try to include everything I can. But mostly it would take foam, stretch fabric and latex. The mask, feet and other parts would be molded in clay to form in latex.
Basically it follows the pattern of other bear, gorilla and monster suits made by Janos Prohaska in the 60's and 70's. Just use glue to create the sparse hair look. (*But watch out you may start looking as if you are wearing shorts as the hair rubs off around the edges of the padding and where your hand and arm sweep against the glued on hair.

)
Geno - Believe me, all those monster suits stink after being worn a couple of times. Patty was made of parts from other suits - not created brand new. The horror that is
the funky sweat smell is something all stuntmen who wear suits must face.

Here I simply glued some foam together using spray glue and stretched a tee-shirt and spandex pants over it to make "muscle masses moving."
The TOP PHOTO of Patty is the one I used in a psychological experiment over at the BFF. I horizontally flopped the pic and composited Patty onto the street in front of my house. I then said this was a suit I was working on. I was then told by several people that it didn't come close to the incredible detail of Patty. That is an example of why no suit (not even Patty herself) will suffice.

Here I sprayed some glue and paint onto the fabric and chopped up a black wig. I just wanted to see how hard it would be to create this type of look.

Same TOR mask on my stunt dummy. On the left I used sunglasses to hide the eye hole. On the right I left the LEFTeye hole open and stuck a fake plastic eye in the RIGHT eye socket.
I also widened Tor's nose since it was not quite as wide as Patty's and made the forehead and jaw sharper. I did this by molding clay with my fingers and pressing the clay into Plaster of Paris. I then poured latex into the Plaster Mold I'd created. You can do this with bathroom chaulk or glue too if you don't have latex. I made feet and footprints (with and without dermal ridges) the same way.

Here you can see the problem Heironimus described on the actual mask used to build Patty's face. The man wearing the mask here is a giant (literally) and he can look out of both eyes. Most people couldn't. Still... some glue and latex could fix this up and one fake eye (as described by Bob H. and demonstrated above) could solve the "eye away from the hole" problem.

Here's me wearing the TOR Bigfoot mask I threw together for Halloween. You can see the problem that occurs. I can put one eye against the opening, but the other shows a gap. All you need is one fake eye and some blur.
The problem is not that no one in the creature fx world can recreate Patty. The problem is that it would hurt their reps to do so as the pros look at Patty as simply a tossed together joke suit. If people want to believe it then that's fine with them. They could care less.
Me? I'm still talking to a few people. Ran into some recently and hope to learn more. Nothing a guy like me could build would change any minds that are set in stone, but I would love to find some part of Patty still around.

I deliberately recreated a few of Patty's pad lines. The hands I just threw on. I didn't take the time to put the arms together.
I could make the elbow joint anywhere I want. I could build the shoulder lower or make the legs shorter. It just depends on what you want. Study the suits and how they are made and you can also make "muscle masses moving" on your next Bigfoot hoax... I mean sighting.
