Atlantica is a world based on the 1989 Disney film The Little
Mermaid. A cutscene will show that things will be a little
different here. The first thing to do will be get used to the new
Use to swim around, as in walking. Press
to rise and to dive. Release them to stop rising
or diving. After you've got the controls, your task will be to
follow Flounder around. You should know when you're finished after
a short cutscene where Sebastian tells you you're doing a good job.
Next will be self-defense, where the tutorial will be interrupted
by a Heartless attack. These Heartless will look similar to jelly
fish to match the theme. Attacking is exactly the same as attacking
above-ground, other than adding on diving, rising, and moving
around in the new aquatic atmosphere. After the battle is over, hit
the clam with your Keyblade to find Sebastian, Flounder, and a Save
After opening the clam, you'll be asked to go to the Palace with
the group. Trident markers are lined along the walls, pointing out
the way to go and making the trenches easier to navigate. You will
now have the option to choose Ariel as a new party member. Follow
the trenches to the Undersea Valley. Follow the markers starting
from the right of the circle, then go to the Calm Depths. The
strong current will make it impossible to swim against it, so
you'll have to follow the current into a pathway on the right. Keep
swimming to the right to make it in during the strong current.
After making it in, go to the other side for another path. This
leads to the Undersea Cave. Then rise up to the Undersea Gorge.
Follow the markers, the last one leading to Triton's Palace. Here,
just go straight forward to Triton's Throne, where you'll see a
The oddly familiar Crystal Trident
After the cutscene, backtrack to the Undersea Gorge. Here, a
secret path behind a boulder will be pointed out through a short
cutscene. Go to the boulder for a cutscene in Ariel's Grotto. After
leaving the Grotto, go to the Undersea Valley. A dolphin is
constantly swimming around the area. Try to hitch a ride on it. Go
about 3 laps and it should leave, then, get to the Calm Depths. The
dolphin will be able to swim against the current. Go to the last
opening on the left. This path should lead to the Sunken Ship. In
the ship, after getting attacked by Glut the Shark, open up the
treasure chest for a Crystal Trident.
After leaving the interior of the ship, the shark will attack
you - it will now attack at random times until you reach a certain
point in Atlantica's story.
Glut the Shark
Glut's usual attacks will be lunging at you with its teeth.
These attacks should be easily avoidable. After a lunge, Glut will
stop in place to prepare for another, giving you time to attack and
then dodge before-hand. While Glut is still trying to bite you,
going near it will get you hit. Try to use magic in these
instances. Glut is weakest against Thunder.
You can now leave the Sunken Ship to go back to Ariel's
After a long cutscene, go back to Triton's Throne for another
cutscene, where Ursula gets herself involved in the world's story
as the main villain. After the cutscene put Ariel in your party,
and get back to the Sunken Ship by once again catching a dolphin
ride in the Undersea Valley. After another shark attack, get to the
remains of a ship next to a large rock with a strange design on it.
Make sure to have Ariel in your party to get Sebastian to help you,
and the rock will lower into the ground and open up a new path.
This path will lead to the Den of Tides. Follow the path on the
left to the Tidal Abyss. This leads to a pretty straight-forward
path to Ursula's Lair.
Ursula has stolen King Triton's trident, but does not use it in
this battle. Rather, she fights by swinging her hands and
tentacles, and every now and then, she will spin vigorously round
the room, injuring Sora and company if they come near. This is the
most difficult attack to avoid, so ignore everything else when she
does so, and concentrate on swimming up and down to avoid her when
this happens. Flotsam and Jetsam are also in the lair to deal
damage to Sora, however, they are simple to avoid, and Ursula will
use cure on them if they are both defeated, so it's easier to
ignore them, and concentrate on Ursula.
It should be noted that in Ursula's lair, there is a huge
cauldron in the center, filled with color-changing liquid. The
color of the cauldron does not indicate what kind of spell needs to
be used on it, only what kind of spell Ursula will spawn from it.
Launching spells at the cauldron will eventually cause a massive
amount of energy to be released, stunning Ursula and her lackeys.
Ursula will also throw some kind of magic potions to activate the
cauldron, however, if there is little to no inervention, Ursula
will use spells of her own to damage Sora and co. The easiest spell
to cast onto the cauldron is Fire, as it consumes little MP and it
is the first on the Magic menu. You may lock on to the cauldron to
cast the spell, though it should be noted that physical attacks
will not work on the cauldron. Physical attacks will refill your
MP, so if you find you're low, make sure to attack Flotsam and
Jetsam, as they refill your MP more than other enemies do.
Once Ursula is stunned, take this opportunity to use physical
attacks on her. It is also possible to attack her while she is
conscious, however her HP will go down very slow, and she will use
her spin attack after two or three hits, so it would be better if
you attack the cauldron.
Her attacks are few but rather unpredictable, so the key to
winning this battle is the cauldron at the center of the lair to
incapacitate her. Like all other boss battles, do heal when
After the battle, you'll get a new ability - Mermaid Kick. This
lets you swim against currents and also swim faster. Now go back to
the Calm Depths. All the way at the end of the tunnel is an area
marked with "???". Go inside to find Ursula.
In this area, Sora and company will confront a gargantuan
Ursula, this time, wielding King Triton's trident. It should be
noted that if Sora uses any form of Aero magic here, this will
strengthen Ursula. She does an attack which looks somewhat like
Thunder; these attacks increase in power and quantity when she
raises the trident. She occasionally blows air currents into Sora's
chest, dealing substantial damage to him. When she has only one HP
bar left, Ursula can open her mouth to use a Thunder-like laser,
which will damage Sora if he gets in the way. That being said,
equipping at least one Thunder or Thundara Ring will make this
fight a lot easier since you will take a lot less damage from most
of her attacks.
Her only weak point is the head, so it is best to use physical
attacks on it. Try and get behind her head, and start bashing away
at her. This can be done best by swimming over her head, and then
come down. Occasionally Ursula will push Sora away from her head,
so get as close to her as you can. Don't be shy about using the
Keyblade - and do heal when necessary. Aim for the back of her head
and attack from behind as much as possible. However, since Ursula
is always turning to face you, this makes it difficult to hit her.
When she starts to gasp as if hurt or tired, swim behind her head
and chain combo attacks to the side or back of her head, and swim
away when it starts to get dangerous. Magical attacks can damage
her as well, but normal combos work best, since she has a triple HP
As Flotsam and Jetsam have already been eliminated after the
first battle, you do not risk being damaged by either of them in
the second battle.
If you are in front of Ursula when she starts to inhale water,
use Mermaid Kick to swim away as fast as possible until she cannot
inhale anymore. If you do not, she will bite you; not fun. She
always declares her other attacks - a bubble attack (avoidable with
Mermaid Kick) and raising the trident indicates that she is going
to form a circle of damaging magic around her. Swim away to avoid
that one. Your prize for winning is the Thundara upgrade and
another Ansem Report.
After the battle, you'll get the Trident back. King Triton will
then allow you to lock the world with your Keyblade. After this,
you can leave to the next world.
