, i thoght it would be neat to have a squeeze bulb or a part of the doll with a bulb inside that when squeezed would make the dolls tongue move in and out a little bit in its mouth (like french kissing ) it could be done (the perfect 10 doll had a bulb but was made for suction (oral sex) this would work something like that but would push a part that would inflate a little and push the tongue in and out !!
