The eyelids are removed from the bust and spheres are inserted to show where the eyeballs will be on the final animatronic.
With the sculpting complete, mould making begins and clay walls are constructed around the halfway point on the bust. The clay is sealed, and a fibre glass mould is made of the front half, then the back half to create a rigid mould of the model.
From the mould, a silicone skin is cast. Slicone is used to give the final piece a 'translucent' look to it and give the feeling and movement of real skin.
