Crystal Trident

The Crystal Trident is an item found within the Sunken Ship in the bottom of the ocean kingdom, Atlantica. It is supposed to have the power to reveal Atlantica's Keyhole. Once Sora found it, he brought it to Ariel's Grotto, but it was destroyed by King Triton before it had the chance to fulfill its task. The Crystal Trident was restored after the defeat of Ursula, when Triton used the power of his trident to reveal the world's Keyhole.
