Swimming in the perfect blue water between the reef islands, you swam to a place where you had never been before attracted by the unprecedented beauty of nature. A school of silvery fish flashed near, almost crashing into you and plunging deep between the reefs and various algae.

And suddenly you notice the Reef Na'vi. The turquoise guy worked furiously with his hands and a strong tail. Looking down, you notice that his foot is stuck under a stone, trapping him, and in a panic, air bubbles burst out of the guy's throat. You know that the reef Na'vi is likely to be hostile to you, but is it possible to leave him in trouble like this? Your thoughts were racing in your head, and your eyes were focused on Na'vi.
