Mega Potion (30%)
|Cast Aero and keep casting Fire at it. Once you run out of MP keep attacking it with the Keyblade. It's only attacks are a bite and a damaging shove, however both attacks can be slightly negated by the Aero shield. Use Potions to heal.|
After its defeat, examine the button to open a new passage to the Den of Tides. In this area go straight but then take the right path to get to the Cavern Nook which has two clams, open the smaller one to get a Mega-Ether and the bigger one for a Save Point. Now return to the fork in the previous area and take the path to the right, go straight ahead to the Tidal Abyss then go ahead, defeating the Heartless along the way, to Ursula's Lair.
|For this fight you'll need lots of Ethers or you can keep attacking Flotsam and Jetsam for extra MP. Use Fire on her cauldron when it's red and Blizzard 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 Aero for any needed help against her attacks. Use Potions to heal.|
|Flotsam and Jetsam|
|They do not cause serious damage however they may take out a large amount of health. They have no extra defenses like Ursula however they get in the way. Defeat them for extra MP in case you run out of Ethers.|
After defeating her Flotsam and Jetsam dissipate and she will disappear into what appears to be a portal. You'll then learn Mermaid Kick, which is needed to reach Ursula 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 clam is hanging from the wall however is shut tight. Leave the area and enter again to make it appear close to the clam, keep attacking it to make it blow up opening the clam dropping a chest, open it to get a Mythril. Now head back to the Calm Depths, and take the exit straight head to ??? if you're coming from the Sunken Ship area.

|This fight requires a lot of handiwork, you must absolutely cast Aero 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 Aero. When she attempts to suck you in you must counteract and use Mermaid Kick to get away from her, if she sucks you in she will bite you, however again, Aero will negate the damage. Once you get through most of her HP she will use her most powerful attack where she raises the Trident to call unto several beams of light to jolt you at once, this will take a large amount of health, even with Aero. Use Cure 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.|
After defeating Ursula the Trident will be out of her grasp and you'll return to the palace, where King Triton will tell you that the world's Keyhole is in Ariel's Grotto. Head to the Grotto, and in he cutscene, Ariel will use the trident to reveal the Keyhole with Sora locking it, ending Atlantica's story. Ariel will give you the world's Keyblade, the Crabclaw from her collection of do-dads and thinga-ma-bobs.
