Pick a "volunteer" to be the dead Chief Shortcake (adult leader) and have him lie down covered with a towel/sheet except for his head.
Have each boy repeat a line on what to do with Chief Shortcake, such as: burying the Chief with all his worldly possessions, should be burned in a great ceremonial fire, put in a cave and seal him up, and so on for as many as you need. The last Indian says that they are all wrong, "I bury Shortcake," and squirts whipped cream on Chief Shortcake's face.
