P J Sparkles was a cute little doll made by Mattel in the late 80s who sparkled when hugged thanks to a 9v battery in her back.
P J SParkles had little lights in her bracelet, hair bow, earrings and a little heart on her chest.
If you don't remember the doll, you might remember the advert:
#P J Sparkles, shine a light on me. Shine! Shine! Shine! When I give you a hug, you light up with love. And all through the night, when I'm holding you tight.#
Here comes P J Sparkles, she's lighting up the sky!
