A cookie jar was left as an offering on the altar. But the spirits were insulted — cookies?! They cracked the cookie jar wide open and unleashed a devastating calamity upon the land, cursing the fool who dared mock the sacred altar with snacks.
Additional thoughts
Picture a solemn stone altar in a dark shrine. Someone nervously sets a cookie jar on it. Lightning cracks the jar apart, and a wave of misfortune pours out like black smoke. The absurdity of offering cookies to wrathful spirits makes the punishment memorable.
Quick recall
A cookie jar offering on the altar enrages the spirits, who unleash calamity.
