Unsinkable Ship Island is an island about the Titanic.
You're in a small town and you walk around until you get to the docks. You pick up some rope, which will be important later on. There you meet Lucy and Sarah-Mary. They are orphans who are going on the New York to their aunts. They give you a ticket, and you board the New York. There are big men, who want to kidnap you and your friends. You run to the point where the New York almost crashes into the Titanic. You, Lucy and Sarah-Mary are thrown off the ship by the men and onto the rails of the Titanic. You use the rope and pull the three of you up, whem you realize you made it up with a small locked box of the mens.
