Trident Cave

Trident Cave is a cave above the Moon Pool on Mako Island. It has a secret entrance near the volcano, that opens up during the Full Moon or full moonlight.

A pathway leads to a larger room that has a circular carving in the wall, with a trident head in the middle. When a merman touches it on a full moon the carving will transform into a watery portal leading to a underwater dimension were the Trident is located. When a human touches the trident head a portal will open in the floor and they will fall through into the Moon Pool and will be transformed into a mermaid or merman.
