The pearl you need is the giant pearl. Once you use the starfish (from Poseidon's statue in the museum), you can enter the realm and swim through the underwater maze to the cave of the Hydra. Before you enter, get the pearl from just outside the cave.
You go to the left corner from the pearl and you go in.
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.
