From the eBay listing: You will have to look for a long time before you find this doll that STILL TALKS LOUD AND CLEAR as this one does. Even those being sold mint in box usually do not talk anymore. She is wearing her original outfit and comes with her box which is in fairly good condition. She has no scratches, breaks or odor. When you press her right arm backwards until you feel a click she will say, This is my right arm. When you do the same thing to her left arm she says, this is my left arm. When you raise her leg up until you feel a click she says, I have five little toes. When you push the button on her tummy she says, your'e tickling me. And when you press the button on her back she says, hold me tighter mommy. She also says, I love you mommy. She has a battery compartment on her lower back with requires one D battery which is installed. She also has a lever on her back which slows down and speeds up her voice. Not sure why that was included because she sounds funny when in the very slow position.
