You are a real, live mermaid who lives in an undersea palace. Your neighbors are the royal campers of Prince and Princess Island. Every summer they come to play games and learn how to be above-water royalty. You stay out of sight of the humans on land, but what will you and your sister, Marina, do when the humans hurt the ocean with trash and pollution? It might finally be time to show your face (and your tail) to your royal neighbors, because they MUST learn how important it is to protect the ocean and keep it clean. YOU choose what happens next!
