This is a white shot mug shaped like a skull. It came as a set of 6 with a decanter marked with a message underneath, such as "Name Your Poison" or "Lay off. This Is The Old Man's Private Stuff" under two crossed bones. The decanter stopper was shaped like a matching skull. Often packaged as a "Spirit of Luau" kit containing a plastic lei, fish netting, and sea shells. Examples have been found from several Japanese companies, marked Norcrest, Enesco, or Nasco Del Coronado.
