I vaguely remember that you had to get the starfish (of seadollar, I forget since I finished Mythology Island when it first came out and haven't been on for a while :P) and go above Hades Temple with the rocks that were shot up with the gas.

In Poseidon's realm, you click on her.

In the realm of Poseidon is a beach and what should be a sea, but resembles a lake. The maze and the Hydra cave are below the surface, along with Poseidon's throne room.
