once upon a time there was a mermaid and a human the mermaid was a boy named dipper/ mason pines, and the human was a prince named bill cipher, dipper was fascinated by humans and fell in love with one as we know as bill but when dippers great uncle found out he wasn't so happy and was forbade to go to the surface again, dipper, desperate and longing to see his prince sought the help of a sea witch named Pyronica as well as her minion Gideon, pyronica said that dipper could have his prince by becoming human...but with a price....you see if dipper couldn't get bill to kiss him before three days then he'd become pyronica's servant forever and he had to give up his voice, dipper became human and met his prince once more...but...a boy with pitch black hair was said to marry his prince.... but! the boy was actually pyronica and after dipper found out he crashed the wedding and was able to regain his voice by smashing her magic shell but he wasn't able to get bill to kiss him and he turned back into a mermaid but in the end pyronica was defeated and dipper and bill got married and soon they had a beautiful baby girl named harmony

she was blonde like bill and had beautiful brown eyes like dipper's
