Store bought? Really? I hate to break it to you, but I think everybody is aware that the plastic skeletons we put in our yard ALL came from a store. I don't think we're fooling anybody.I agree. Red LED eyes just screams: "STORE BOUGHT, STORE-BOUGHT.."
I usually pull out my soldering iron and put different colored LEDs in their place.
You can probably dress up the teeth a bit with some acrylic paints.
Good deal, though.
