AU Update Part 2 (Ideas)

This takes place on the surface where humans and monsters coexist. I was thinking to use my oc Salea as a main character if not Zoey, the main character travels the world by sea with skelebros Sans and Papyrus who pilot their own boat they use to travel from port to port, from island to island. The boat is their home away from home that is a bit of ways from the lighthouse that sits on the cliff that shines its light across the Gem Sea. I was thinking that Sans could be the little brother, but I would like to know your opinion to either keep him as is or change him. The Gem Sea is home to them in a way, it got its name after discovering that many treasures can be found beneath the depths after a battle between two pirate ships happened many years ago. Both ships have sunk and the brothers have been fascinated to know more about the event as well as the sunken treasure that had remained untouched for so long. The only piece of the treasure they had kept was of a blue star-like diamond Sans wears around his neck he keeps hidden away while not aware of some danger hidden around a corner.

The boat itself is painted in blue and white. It's not too big, but not too small while going by the name Dame le Grace for to the brothers as well as Alphys and Undyne think the boat sails with grace while having a charm to it in a way. Papyrus thought it needed a name. XD

Tell me what you think? Suggestions and feedback is welcome. I thank you all again for your help.
