 Three of the dummy heads used from "Night of the Living Dummy III"  appear in this story. The broken, severed heads of Slappys "rivals"  in Jimmy OJames home after Slappy are the heads of the Rocky and  Zane dummies. Slappys damaged, severed head in the finale is  actually the head from "Night of the Living Dummy III", when Mr.  ODell tries to glue Slappys broken right eye back on his cracked  face.
