The only 'head' morphs on the list other than teeth and tongue are her eyes, which are lovely.  I adore this character.  I don't have anything labeled smiles or frowns though.  None of the other face parts become targetable, or appear on the head's morph list.

This is the link the the character, which doesn't say it has that morph, but I thought over V 4.2 that it would work?
