Full / part animatronic models by two different people. I was actually like wow they are very, very good so I thought I would bring them up here. It could be useful for you lot... if not now perhaps in the future.... Basically I thought I would share for your benefit if you were not aware of them. I only just seen them both a few moments ago myself.
