You've been constructing your own sail boat in hopes of traveling the seven seas. You worked day in and day out so you could finish the boat in time for your intended departure date. A few days before said travel date, you successfully finished construction. You then prepared everything you needed for the voyage.
Two days after your ship's maiden voyage you got caught up in a pretty bad thunderstorm. Your ship was obliterated by the lashing of huge waves and the multi-directional tug-of-war of strong winds.
The next day, you find yourself washed ashore on a huge island infested by different species of snakes. You don't have any place to run to so you need to find a way to escape this life-threatening island. (You wish you were an ophiologist.)
