>>9498944Don't know about the shoulders but NECA legs use a weird cup and peg system that goes through a hole in the crotch, I took a small flathead screwdriver and stuck it through the space in the crotch and pushed the sides of the cup outward till I was able to pull the peg out. The cup is malleable so you could heat and push the sides back in for reassembly but I left them splayed on this Scorpion Alien so I could "replicate" the exploding action feature of the original by pulling the legs, tail, and back spikes off.
