Sea Foam

Elliot lives in the little harbor town of Monta with his sister and his mother, trying to provide for the family because his father passed away. Without warning, buccaneers attack Monta, capturing his sister and him.
Elliot is separated from his sister and sold to a trading ship, where he befriends the captain. The crew commits mutiny, and the captain calls Davy Jones, the mysteriously powerful pirate, right before dying. Davy Jones gives Elliot mysterious powers, including the ownership of a magical ship. With this ship and a crew he picks up along the way, Elliot goes on a quest to find and save his sister, no matter the cost.
