Harvest Hunt gets decent mileage out of its hide and seek premise
We have been cursed with a terrible devouring monster. Each harvest, one villager must don the ceremonial, mildly magical mask, and enter the fields alone, to gather the precious life-giving ambrosia before the beast can befoul it. For five nights you must do battle, or evade its ravenous clutches.
Those of you who have known your own Devourer are surely thinking: Only five nights per year? Luxury. Harvest Hunt is good, though.
