There is a castle in your pink sea. Inside the castle is a world straight out of a fairy tale. Your home, like a mermaid princess. Your home, all alone with no one else. You can control everything with magic. You go ashore, transform into a human, and live well on land. There is a house near the beach. You go back and forth, living alternately on land and in the sea.
There is your castle in the sea. The pink sea waves guide you.
