Everyone at the beach is geared to spend the day in and around the largest tidal pool. The Crab family, Starfishes, Oysters and others are invited to the big party. Janice, a pale pink jellyfish wants to play in the tidal pools but her family and the sign nearby the tidal pools say she isn't allowed inside. What happens when an extra-large wave washes her into the tidal pool? Will she be allowed to stay and make new friends or will one of the Chief Gulls who patrol the area pick her up and drop her back into the ocean? What about the rainclouds that are threatening to dump rain on everyone? Will it ruin the party? Or will the other sea creatures in fear of her poisonous tentacles leave her friendless?
