How do you find Zeus after you get all 5 sacred items on Mythology Island?

The Five Sacred Items :

1. The Rare Flower -- from the Garden of the Sphinx once you open the flow of water from the aqueduct (there are 4 valves and some wooden channels)
2. The Nose Ring -- from the Minotaur if you can make it through his Labyrinth (maze)
3. The Hydra Scale -- from the beast in the cave in Poseidon's realm
4. The Giant Pearl -- from underwater, just outside Hydra's cave
5. The Cerberus Whisker -- from the ferocious dog-monster of the Underworld

You will also need pomegranates from the Sphinx's garden, on a tree above the creature, and a starfish from Poseidon's statue in the Museum of Olympus.
