[[File:Donald Duck AT KH.png|60px|left]]

Here there are numerous {{Wtext|chests|t}} here, from the entrance go straight and then drop straight down to find a ship with a broken hull, enter inside to a {{Wtext|chest|t}} that contains an {{Wtext|Elixir|i}}, then get out and go up and into the ship, the {{Wtext|Shark|c}} will swim by. Now inside the ship there is a {{Wtext|chest|t}} straight ahead but forget it for now and go to the back of the ship, there's a chest to the left containing a {{Wtext|Mythril Shard|i}}, there is a hole underneath the stairs that leads to a {{Wtext|clam|t}} containing a {{Wtext|Mythril|i}}, now head back to the {{Wtext|chest|t}} that we left and open it to get the {{Wtext|Crystal Trident|i}}, however the {{Wtext|Shark|e}} will appear as you approach the {{Wtext|chest|t}}. Now head back outside, you can fight the {{Wtext|Shark|e}} for 100XP. There'll be an exit lower down from the main one, but go to the right of it to get a {{Wtext|chest|t}} containing a {{Wtext|Mythril Shard|i}}, now head through the exit to the {{Wtext|Undersea Gorge|l}}. There's an inactive crater ahead of you, hit it to cause a stronger current, head through it upwards to pop out the large {{Wtext|Treasure Chest|t}}, open it to get an {{Wtext|Orichalcum|i}} then head to {{Wtext|Ariel's Grotto|l}} to the right and swim up to the trident-head shaped emblem for a cutscene.

During the cutscene, {{Wtext|Sora|c}} places the {{Wtext|Crystal Trident|i}} into the emblem, however before anything happens {{Wtext|King Triton|c}} show ups and destroys the {{Wtext|Crystal Trident|i}}, causing {{Wtext|Ariel|c}} to swim off crying. He also exiles the party from the World however {{Wtext|Sora|c}} and his party decide to stay regardless of {{Wtext|Triton|c}}'s ruling. Meanwhile, {{Wtext|Ursula|c}} tricks {{Wtext|Ariel|c}} into helping her take {{Wtext|King Triton|c}}'s {{Wtext|Trident|i}}. Once you're back in control, head out of {{Wtext|Ariel's Grotto|l}} and once you reach the exit to {{Wtext|Triton's Palace|l}} a cutscene will play showing {{Wtext|Ariel|c}} escorting {{Wtext|Ursula|c}} to {{Wtext|Triton's Throne|c}} to get the {{Wtext|Trident|i}}. Swim all the way to {{Wtext|Triton's Palace|l}} and in a cutscene {{Wtext|Triton|c}} is shown weak and helpless on his Throne while {{Wtext|Ursula|c}} basks in the glory of the {{Wtext|Trident|i}}, {{Wtext|Flotsam and Jetsam|c}} note to {{Wtext|Ursula|c}} that the Keyhole is not in the Palace and her exclaiming in shock, however {{Wtext|Sora|c}} and his party make it back to the Palace but {{Wtext|Ursula|c}} makes off with the {{Wtext|Trident|i}}. {{Wtext|Ariel|c}} rejoins the party determined to defeat {{Wtext|Ursula|c}} and get the {{Wtext|Trident|i}} back with {{Wtext|Sebastian|c}} tagging along, before you go, {{Wtext|Triton|c}} gives a small hint on how to defeat {{Wtext|Ursula|b}} by casting magic against her cauldron. Save and head to he {{Wtext|Sunken Ship|l}} map, defeat the {{Wtext|Shark|b}} to allow {{Wtext|Sebastian|c}} passage to the button close to the door with the strange glyph on it.

{{tab|Ursula I}}

|strategy=For this fight you'll need lots of {{Wtext|Ether|i}}s or you can keep attacking {{Wtext|Flotsam and Jetsam|e}} for extra MP. Use {{Wtext|Fire|w}} on her cauldron when it's red and {{Wtext|Blizzard|w}} when it's blue. When done right she will be stunned momentarily allowing you to land a few combos on her. Once she's gained consciousness she'll twist about her tentacles causing massive damage. Cast {{Wtext|Aero|w}} for any needed help against her attacks. Use {{Wtext|Potions|i}} to heal.}}

{{tab|c}}

{{tab|Flotsam and Jetsam}}

|strategy=They do not cause serious damage however they may take out a large amount of health. They have no extra defenses like {{Wtext|Ursula|b}} however they get in the way. Defeat them for extra MP in case you run out of {{Wtext|Ether|i}}s.}}

After defeating her {{Wtext|Flotsam and Jetsam|e}} dissipate and she will disappear into what appears to be a portal. You'll then learn Mermaid Kick, which is needed to reach {{Wtext|Ursula|b}} for the second battle with her. But for now stay inside her lair and look around, there's a sea urchin hiding underneath the ground and a large {{Wtext|clam|t}} is hanging from the wall however is shut tight. Leave the area and enter again to make it appear close to the {{Wtext|clam|t}}, keep attacking it to make it blow up opening the {{Wtext|clam|t}} dropping a {{Wtext|chest|t}}, open it to get a {{Wtext|Mythril|i}}. Now head back to the {{Wtext|Calm Depths|l}}, and take the exit straight head to {{Wtext|???|l}} if you're coming from the {{Wtext|Sunken Ship|l}} area.

|image=Ursula (Giant) KH.png

|strategy=This fight requires a lot of handiwork, you must absolutely cast {{Wtext|Aero|w}} at the start of the battle and go crazy on her face. She's got light attacks that pierce heavily on your health to heal frequently as well. Another attack is where she will blow bubbles your way, these do not do much damage, and can be easily negated with {{Wtext|Aero|w}}. When she attempts to suck you in you must counteract and use {{Wtext|Mermaid Kick|w}} to get away from her, if she sucks you in she will bite you, however again, {{Wtext|Aero|w}} will negate the damage. Once you get through most of her HP she will use her most powerful attack where she raises the {{Wtext|Trident|i}} to call unto several beams of light to jolt you at once, this will take a large amount of health, even with {{Wtext|Aero|w}}. Use {{Wtext|Cure|w}} as soon as possible to avoid impending knock out. The best place to attack her is from the back at the base of her neck, as she will keep attempting to turn around, she will push you along and automatically keeping you away from the beams of light.}}

If you want to get a 100% completion, you will need to return to {{Wtext|Atlantica|l}} to use the {{Wtext|White Trinity|i}}, which can be found in {{Wtext|Triton's Palace|l}}.
