Mr. Hyde Behaving Badly

What every fashionable ghoul like you needs to wear on Halloween night: flashing ring light-ups adorning your claws. The witch, skull, and cat are made by Illuminix. They can either blink slow, or fast, or you can leave the red light on. I don't recall who makes the metal skull ring in the middle, but you twist the skull a little to turn on his eyes, which change colors as they blink. The witch has all the right colors and demeanor to be Halloween-witchy, but the black cat is my favorite. His eyes glow red (but the battery's too weak to show it in the photo).
