Martha is back for a new adventure.

Martha is heading out to her favorite vacation spot-the beach! But on the way, the wind lifts up her favorite pink straw hat with a flower on the side, and carries it into the marsh, far out of reach. Then, before her very eyes, Martha's hat goes on an unbelievable journey, bringing joy to all who find it. Follow along as the whole beach gets in on the game, and Martha has the perfect, unexpected vacation.
