Now that you mention it, I did find a packet of a Russell Stover chocolate marshmallow egg when I cleaned out the trunk of the car recently.
From Easter...must have fallen out of the bag and rolled into the well.
My husband had no qualms about eating it immediately.
Lest you worry, the Valentine's candy is long gone. That was our 25th anniversary and we spent it at a romantic hideaway with a 5 star restaurant.
