You're a siren, swimming in the ocean, just enjoying your day. You swim to a rock and lay there, flicking your tail to keep it wet. As you were laying there you saw a ship in the distance. Before you knew it a net was thrown over you, capturing you.

Soon enough you were brought to a palace. Once inside you were put in a glass encloser filled with water as you were being brought to the king.

"Here you are, your majesty. Your siren." Said the pirate.
