I just found that there is a mysterious quest game on Second Life; it is called The Pot Healers of Numbakulla.
When you arrive at the island, you see a rather major ship wreck.
You will also see many chests where you can spend L$0 for exploration clothing. Wear those clothes and start exploring this lovely sim.
Apparently, the major quest of the game is to continue the tradition of a long dead civilization: Grow and maintain the Numba fruit. To do that, you need to repair the sacred pot that holds the water needed to bring life to the seeds of the Numba tree.
Please explore and work on the game. Let me know what you find!
