It's raining but Laura has a new raincoat! She and her mum are planning to go out to see a few hydrangea flowers that are growing. Hamtaro heads to the clubhouse, but only a few Ham-Hams are there due to the rain. Hamtaro tells them of where Laura is going and so the Ham-Hams go there too. Pashmina finds Penelope and the Ham-Hams in trouble as they are surrounded by frogs. She comes and assists them by being bait. This works and they all are free. They eventually get to the hydrangea flowers!
