The Hidden Mako Island Cave
The Hidden Mako Island Cave is hidden within the rocks of Mako Island. It can only been seen by the human/mermaid/mermens naked eye if the full moon is over the Moon Pool. It is most likely this was designed so land dwellers could fall into the moon pool and experience a fish life too or it was used to have a hidden pool for the trident. It is also known as the land entrance to Mako. If you are a merperson and touch the trident shape when you dont have the trident it will open a portal to the trident chamber. If you are a human with the trident you will fall into the moon pool. If you are a human without the trident you will either fall into the moon pool during a full moon or open the trident chamber.
