Vintage Rainbow Brite and light up Sprite

2003 vintage Rainbow Brite doll and Twink. Pre-owned, original owner, never removed from the box still attached in original box and packaging. Also in plastic to preserve box. Overall condition of box is excellent there is a small crease in the front. This set includes DVD of one of the original TV episodes. On twink Sprite doll it says to press the tummy and it lights up, there is a try now hole but when I tried it it doesn't work. I'm assuming the battery is dead. Not sure because it's never been removed from the box. 80's nostalgic Timeless classic for any Rainbow Bright lover.
