Holodrum
With the Bright Sun retrieved, you'll be warped out as usual and receive another message from the Maku Tree. The Bright Sun has strengthened him, and he has seen that the powers of darkness still grow somehow.

He has also dreamt of the waterfall on the mountain north of Sunken City. The next esscence could be there, but what does the waterfall hide...?

Natzu (Summerland)
"Natzu" is Japanese for "Summer".

This area is different depending on which animal companion befriended Link.

Regardless of the animal companion, there are always three caves to be explored:
 * 1) a fairy fountain;
 * 2) the home of a Deku scrub (who refills Link's seed satchel);
 * 3) a cave with a 50 Rupees chest (it can be accessed only after Link retrieved the flippers in Sunken City).

Sunken City
Items that can be collected:
 * Gale seeds
 * Master's diplom and Zora flippers
 * Gasha seed (treasure chest)
 * trade Goron Vase (see below) for a fish
 * trade mushroom (see below) for a wooden bird

First of all, Link can collect Gale seeds from the tree in this town, but only in summer.

Then, Link meets Dimitri, a friendly Dodongo who helps him reach the northern portion of the town (it's possible to have met Dimitri already in Spool Swamp). There, a master diver resides in a cave. He proposes Link a challenge. The hero must then move to the nearby cave, push the four eye statues close enough to each other, and slash them all at the same time with a charged spin attack: a passage will open and allow Link to reach the chest. Inside is the Master's diplom. Bring it to the master diver, and he'll reward Link with the Zora flippers and a secret: there's a diving hole that links Sunken City to Mt. Cucco. It's actually located near the house of the collector of vases.

Now you can freely explore the rest of Sunken City even without the help of Dimitri. Just east from the master diver's cave there's a flooded house and a Gasha soil. No need to plant any Gasha seed there: it's a spot that only produces rings from tiers 1 and 2. Another cave can be reached in summer only: it holds a Gasha seed.

In winter, Link can reach Syrup's shop. Nevertheless, the witch Syrup cannot make any potion until Link brings her a mushroom.

There's a second diving spot, just south of Syrup's shop (note that it cannot be accessed in winter). Inside, Link can get another Gasha seed, but then he has to exit in the Woods of Winter. Not too bad: he can use a Gale seed and get back to the Sunken City.

Moblin's Keep
Use the flippers to access the third cave in the north of the Natzu land and gain 50 Rupees. Then, use the flute and your animal friend to access the Great Moblin's Keep from the south-west.

If you defeat the Great Moblin, you can get a Piece of Heart from a chest in the ruined keep.

Goron Mountain
Items that can be collected:
 * Ring box upgrade
 * trade Lava Soup for Goron Vase

Mt. Cucco
Access Subrosia from a portal on Mt. Cucco.

Treasure Grove
The Strange Brothers steal Link's feather, and he has to chase them through their treasure grove in order to get it back.

Spring Tower
After Link got his feather back, he can access a cave near the Treasure Grove that leads to the Spring Tower.

Springtime on Mt. Cucco
Items that can be collected:
 * Piece of Heart
 * trade Megaphone for a mushroom
 * ring
 * Dragon key (actually on the east side of Goron Mountain)

DUNGEON: Dancing Dragon Dungeon
Dancing Dragon Dungeon is a dragon-shaped mine shaft of doom. You'll find the treasures in here have been heavily guarded with monsters and danger to discourage adventurers.

However, the next essence resides in here, and the only way to find it is to face the challenges this trouble-filled dragon holds.

Waterlogged and danger-ridden
The first room, as are many others here, is flooded with water. There is a locked door to the right, so swim over to the left to enter the next room.

This room has a chest you can easily reach: simply push the block two spaces left from it down. You'll find 10 Bombs.

With those extra bombs, ignore the Shrouded Stalfos and hop in the mine cart.

As you ride the mine cart, you'll pass a switch. Don't hit it until you round the curve. You'll switch the tracks, but still head north.

Once again, ignore the enemies and go east to spot a cracked wall. Plant a bomb right by it and head into the uncovered room.

Eight switches, nine pots, and one small key
Here is a simple puzzle: activate all the switches at once. However, there are 8 switches and 9 pots to use. Two aren't needed, but to make things easy, follow this solution:

You'll earn a Small Key as a reward. Now, take it and unlock the door in the first room.
