Pamela Doll was a 20" talking doll made by Worlds of Wonder in 1986. She was called the living doll and she had sensors in her face so that when you pushed them she would say things to you like "I can hear you".
Pamela doll had various cards you could put in her back to change ativities, and different outfits and activity sticker books to go with each card and outfit. When you pushed her belly she giggled.
Pamela ran on 4AA batteries and her original outfit was a white long-sleeved shirt with purple, blue and pink plaid overalls. I still have mine and I wouldn't give her up for anything!
