While playing pirates, Huckle, Lowly, Billy, and Hilda discover a message in a bottle. There's someone out there who's shipwrecked. They tell Mother and Father cat about it, but they think it's just part of the pirate game, so the kids head to Wolf Point Island on their own. Sure enough there's a sailor out there, but when the kids arrive, they are shipwrecked too. So it's a good thing they left a message in a bottle of their own for Mother and Father Cat to find and they come to the rescue. (thetvdb.com)
