I JUST thought about this toy right now. She was a doll, circa 1989/90 or so. I thought of the commercial: "Her name is STARLA(SHA) wherever we go, we put on a show! Lets sing a song- you can sing along!"

I thought about the doll's voice OH MY GOSH, possessed robot, anybody?

The doll was Starla and it was made by Hasbro. There was a commercial up on youtube for awhile, but not anymore. She was a rather creepy doll. Here's a link to a picture.
