Pixie Dragons can ride on your shoulder.
I use a ball and socket armature for the Pixies. Moving the legs to a back position allows the Pixie to belly-rest on the shoulder with their tails positioned around the neck and up to the front for balance. You can position the arms and legs; just don’t spin them around in one direction, since that would tighten the internal thread to the point of breakage.
The wire in a dragon should bend pretty well, you just don’t want to bend it back and forth repeatedly, as for the armature the manufacturers say it can bend up to 28 degrees. I bent the armature as much as I could before it would snap apart, and took the pic below. It is very sturdy and you will feel resistance when it has reached the bending limit.
