Close to the island of Phi-sai grows a rare underwater plant. In your little submarine you go in search of it and during your quest you'll experience a lot more underwater adventures! You'll find items: use them in a smart way, so that they'll help you clear blockades. Good luck!
Use the arrow keys to navigate your submarine. Click to shoot your harpoon at an item and to attach it. Click again to unclasp the harpoon.
