Here's my take on adding a little extra articulation to Twinferno. Basically glued a 8mm ball peg to the end of the arms and snapped the dragon heads on. The tricky part is the pin that holds the lower jaw runs all the way through the wrist, so I had to cut it to fit on the ball joint. I used a small, shallow screw to attach the lower jaw to the head so it can still open and close as normal. I actually did this mod before I saw a similar thread from @blastpak which did the ball peg at the elbow instead of the wrist. Mine does offer a little more articulation and posing options, although I probably wouldn't have attempted it at the wrist had I saw that thread first. I figured I would go ahead and post mine as a slightly different alternative although the end result is mostly the same. Anything to get rid of those horrible curling arms.
