I have finally gotten the mummy over to the pharaoh. He walks very awkwardly, but I guess that works for a mummy. I have also found it difficult to pose objects without moving their joints into awkward positions. I am sure it will get easier.
It wasn't easy to make the mummy walk naturally. I got mine to walk slowly, but it looks like it's kicking with one leg and sliding forward with the other one. Mummies walk slowly, so I made mine walk that way too.
