Taihen na Koto ga Okiru Hi (E55)

"In three days, something incredible will happen in this forest." Three days have passed since that message was left on a large rock. Chipmunk thinks it is just a prank, but Raccoon thinks it might be true. Bonobono and his friends go up the Kumomo Tree's hill which overlooks the forest to see if something really does happen.
