Mac Dre's alter ego The Genie Of The Lamp is the fifth in a limited edition series of bobble head dolls. This version includes a special "chip" that if the battery included happens to work will allow you to hear several of Mac Dre's popular rap phrases. Although protected with a tab to retain battery power, this stock was assembled in 2006, so THE BATTERIES ARE NOT GUARANTEED TO WORK. We've found some do, but some do not. Each doll is individually numbered for the collector. (Battery type: G13-A x 3) Replacement cost for batteries is under $2.00.
