Dipper Pines a young Siren who's never been outside his underwater village Siren Falls, runs (swims) away on his 16th birthday so he can explore the ocean and discovers all of its creatures. Bill Cipher the most fearsome pirate in all the seven seas. He's been looking for a mermaid, merman, or siren to keep as a pet. What happens when Dipper gets captured by Bill? Will they become friends or maybe, just maybe they'll fall in love. This is boyxboy story don't like it? Than dont read it! I will not right smut but there might be fluff. Disclaimer. I do not own Gravity Falls or it's characters. I do however own this fanfic. Unless said other wise the art is not mine.
