The Rocking Tombstone with Raven is an item made by Gemmy in 2006 for Halloween.
The tombstone stands at around 3 feet tall and simply reads "R,I.P", and has a black raven sitting on top of it. When activated via push button, motion sensor, or sound, the letters light up and flash blood red, the tombstone rocks side to side, and the raven flaps his wings, his eyes light up red, and he caws and says "Nevermore!".
