The morph targets are specially created using the isolation method
which means that to create a facial expression you have to use a
combination of several morph targets, which gives a very high level of
control. This allows you to use the 'follow through' and
'overlapping action' animation principles, which results in really
smooth and life like animations.

The jaw with teeth is driven by morph targets as well.

Textures for the eyes and tongue with teeth are included.
