Enter the water in Poseidon's realm. Go past the temple of Hades to reach the temple of Poseidon on the right side of the island. Use the starfish (from Poseidon's statue) to enter. The water is just left of Aphrodite. The giant pearl is close to the Hydra's cave. Swim along the top, right side, and then the bottom of the maze.
you find it in the giant clam in the water where it says dive. :)
Just dive by the circle of darker water and you will enter the underwater maze.
You go to the left corner from the pearl and you go in.
The giant pearl is just outside the Hydra cave in the underwater maze. Dive into the dark water below the Poseidon statue, then go right along the top of the maze, down the right side, and left to the cave.
swim of shore and there it will say dive thats the underwater cave
You click the darker water underneath the statue of Poseidon on the seahorse.
Look in a clam. That's where pearls are made.
under they sea at Triton's palace
a grain of sand gets caught in a clam then it grows with water into a pearl
You do nothing. Its one of the items that you'll have to give to Zeus.
you can dive if you were in Poseidon's beach there is a statue of him with a seahorse there you can dive
the hm dive is not available in pearl.
