First introduced in R.L. Stein’s Night of the Living Dummy, Slappy appears again and again in the Goosebumps franchise. Brought to life with the words “Karru Marri Odonna Loma Molonu Karrano,” Slappy has been an evil and sadistic villain for decades. With this mask, Slappy is depicted with a ventriloquist dummy’s mouth, huge bright yellow eyes and carved brown hair, with lips that form a sinister smile. A dimple has been added to his chin. Fits over the whole head.
