Build the Boat and Escape the First Island.
Boat costs 110 coins normally. (I think)
But it is discounted on the first island, with more than half the pieces already spawned in with the boat.
You must also pay 8 coins for the voyage to start when it gets to the dock.
The Dock will be on one side of the map or the other.
When you start building the boat the Taller side is pointing towards the dock.
Goodluck!
