Vintage 1992 Soma Easter Bunny Troll Dolls Lot set of (3) 4" multicolored rubber dolls with yellow, green and purple hair and bunny ears. They have a button on their belly that when pressed, lights up their eyes. The lights are not working. We opened the back panels on each troll and found that they are powered by button batteries. Unfortunately, we didn't have replacement batteries to check operation. There is no sign of corrosion within the battery cavities. Easter gift, collectible troll
