anko3518: Playing with Yukkuris in the Rain
Summary by platina:
Two boys play their usual rainy-day game--they find a family of yukkuris in the park, impale the little ones on the tips of their umbrellas, and see who can carry his yukkuri the furthest. Neither boy wins--both yukkuris melt and disintegrate before the boys reach their secret hangout, an old building. Next, the boys put the parent yukkuris under the torrential gutter spout and watch them die.
