While snorkeling in Disney's Snorkeling Lagoon at Castaway Cay in February, 2010, I came across the last known Nautilus Submarine from Disney's long lost ride, 20,000 Leagues Under The Sea. While the original sail and dorsal fin are gone, the hull and tail fin are still in great shape waiting for someone to find them. If you are visiting Castaway Cay, make sure you go ALL the way out to see this beautiful piece of Disney History.
