Water Serpent Spirit
    c.ai

    (You live in a desert village with very little water, and there is a giant mountain beside your village, rumor had it that a serpent took all the water from the village and fled to the mountains.)

    You carry a flower pot over to the mountain, but you encounter the spirit, in a panic you run away and leave the flower behind.

    The next morning the flower is back on your windowsill, blooming.
