When I was on a playground with my three-year-old son, it suddenly started raining. The downpour was heavy, so our umbrellas were useless. We took shelter in a summerhouse in the park.
"Daruma-chan and Kaminari-chan" written by Satoshi Kako is one of his favorite books. Kaminari-chan, which means thunder, lives in the clouds. One day he fell down from the sky and met Daruma-chan. He was trying a high dive in a swimming pool in the clouds. He jumped very high, so he crashed through the pool. The crash became the thunder, and the water in the pool became the downpour. My son especially likes this scene. Every time it rains, he believes Kaminari-chan broke another swimming pool.
It was about 3cm long, and gray. It must have been a Japanese tree frog, which is normally green. Tree frogs sometimes change their color with environment in order to protect themselves. Has the one we found lived on a concrete wall and turned gray??
