Sally the baby doll envied Barbie. Not for the reason you think although that did not escape her, but because she had a head that would not swivel. When the bear brothers launched into mischief Barbie could simply turn her head. But Sally couldn’t.
One night Barbie enlisted Ken to “help” Sally get her head unstuck. Sally realized quickly Ken was no genius. “Probably why he chooses to go shirtless,” she thought.
Ken managed to turn her head, but now it was turned to face behind.
She didn’t see the bear brothers light the bottle rocket. But she felt it.
