You must get the next element from the Cave of Flames. First you meet Melari at Mt. Crenel.

Leave Hyrule Town

You can go northwest from Hyrule Town if you have learned the Spin Attack.

Get a Bottle

Go southwest and go down the ladder. Bomb the rock wall, then use your shield to bounce the seed back at the Business Scrub. Talk to it and buy an empty bottle for 20 rupees. You will need an empty bottle soon, so if you don't have enough, play the Cucco Catching game or look at the map to find Kinstone fusion treasures that you haven't collected yet.

Reach Mt. Crenel Base

Exit the Business Scrub's room and go back up the ladder.

Go north until you can go west. To the west, there is a short bridge. Cross it and go west to the next area.

Water a Vine

Go south to the water's edge and use your bottle (see above if you don't have one) to fill it with water. Then climb the leftmost vine to find 20 rupees. Go back down the vine.

There is a weird-looking wall to the right of the vine sprout, but you don't have to go in. There is just a Business Scrub there who will give you a hint on finding the bottle. This Business Scrub might have a Kinstone fusion.

Outside, equip the bottle that you filled with water, and use it on the vine sprout to make it grow. Climb up the vine.

Get Mt. Crenel Mineral Water

Go north and you find a rough wall with boulders falling from above. There are Tektites jumping around. Wait for them to be on the ground before you try to hit them.

West of the rough wall, there is a weird-looking wall. If you bomb the wall and go in, you find 15 rupees and some fairies. However, if you catch a fairy in your empty bottle, you will need to let it go soon, because you will need your bottle for something else.

Southwest of the fairy fountain, there are spiky things on the ground. You will take damage if you bump into them. You can optionally remove them with the Gust Jar.

Go south until you go east. There is a sign and two pieces of a fence. Put a bomb between the pieces of fence, then go inside. Kill or avoid the red Chuchus, then go up the ladder. Go north and you find a shrinking portal, but before you use it, use a bomb on the cracked stone to the right. Then use the shrinking portal.

Go east and follow the path to reach a Minish path. Go north, and at the end, make sure your bottle is empty, then use it on the green water. Afterward, go back to the shrinking portal and press R to go back to normal size.

Get a Piece of Heart

To the left of the ladder, jump down the ledge. Then go southwest. Go past the first whirlwind and go north to the second one. If you don't have any bombs, go west and enter the cave. You can buy 10 bombs for 30 rupees.

Go back to the leftmost whirlwind and use a bomb on the wall. Go inside and pull the mushroom south, then let go of the directional pad to go across. Go north and go up the stairs.

You can use the Gust Jar on the Helmasaurs to pull their masks off and make them more vulnerable to attack, or you can just attack them from behind. Go east and go through the door.

Go south to find a whirlwind. Jump into the whirlwind and use the directional pad to float west to the next whirlwind. Keep floating west to land on top of the cliff. You can press R to stop floating.

Go west past the ladder, then go north to the next area. Bomb the wall between the two tree stumps. Inside, bomb the three stones. The chest on the left contains a blue Kinstone piece and the chest on the right contains 50 rupees, and the chest to the north contains a Piece of Heart.

Reach Mt. Crenel

Exit the cave and go south to the previous area. Go east to the ladder and go up it. You find a Minish path with Tiny Pestos flying around. Kill the Tiny Pestos, then go east and use the Gust Jar on the dust to reveal a tiny crack in the ground. Go south from there and use the Gust Jar on the dust to reveal a shrinking portal.

Use the shrinking portal and fall into the crack that you revealed under the dust to the north. Open the chest to get a red Kinstone Piece. Then climb up the ladder.

While still Minish-sized, go east and climb the tiny vine to reach a cave. Follow the straightforward path and open the chest at the end to get a blue Kinstone Piece. Then go back outside.

Go west to the Minish path. If there are Tiny Pestos flying over it, you will need to use the shrinking portal, kill the Tiny Pestos, then shrink again. Enter the Minish Path, but don't pour the mineral water on the giant sprout. Instead, lift the sprout with R and carry it out of the Minish path, then go east and throw it into the circular hole in the ground. Then go south to the shrinking portal and use it to grow to normal size, and pour the mineral water on the sprout. Climb up the vine that grows from it.

Get Another Piece of Heart

Go west, and go up the ladder. Go to the north wall, then look to the east of it to see a part of the wall with two rocks on each side. Put a bomb between the rocks to open a cave. Go inside. Catch a fairy in a bottle, and take the Piece of Heart. Go outside.

Get the Grip Ring

Go south and go back down the ladder, then go east until you see a wooden bridge to the north. Go north across the bridge and bomb the wall to open a cave. Go inside, pick up and throw a pot with R, then open the chest to get a blue Kinstone piece. Then go up the stairs in the north wall.

The black Chuchus are vulnerable to bombs and can also be hit with the sword if they're not spiky. Bomb the rightmost cracked stone, then push the rightmost block north, and push the topmost block north. Go west, then south, and exit the cave.

Jump into the whirlwind, then float west and enter the second whirlwind, and keep going west to land on the ledge. Then go north and climb up the ladder to the next area.

Go east to find a weird-looking wall next to a sign. Bomb the wall and go inside, and buy the Grip Ring from the Business Scrub (you need it to proceed, so if you can't afford it, collect rupees until you can). Then exit the cave.

Get a Bigger Bomb Bag

You can now climb the rough walls. Go southeast and climb down the rock wall. Before you pull the mushroom, pick up the two rocks to the east of it. Then pull the mushroom east, and let go of the directional pad to go across the gap.

Go west and use the whirlwinds to reach the west ledge again. Keep going west, then go south to jump down from the ledge. Go west and ignore the cave (it's where you got a Piece of Heart earlier), and climb up the rock wall to the next area.

Go east to where you see a sign on a small ledge. Bomb the wall between the two pieces of fence to the right of the sign, and enter the cave. Go inside and throw a bomb into the fountain (drop the bomb then pick it back up with R, and throw it with R). When the fairy asks you the question, answer "Neither" and you will get a larger bomb bag that holds 30 bombs. If you're low on hearts you can exit and go back in and throw in another bomb and she'll heal you. Otherwise, exit the cave.

Reach the Mines

Climb all the way up the wall to reach the next area.

If you want to fuse Kinstones, you can optionally go west and climb down the ladder to reach an area with a doorway on the right. Go through to find the Crenel Hermit. He usually has one or more Kinstone fusions available. When you're done, exit his cave and go back up the ladder.

Go east to find a stretchy mushroom. Pull it west, then let go of the directional pad to go across. Shrink at the nearby sparkling portal, then go south and enter the Minish path. Beware of falling raindrops. Go east to exit the Minish path, then go northeast and use the portal to return to normal size.

Go west and push the round boulder into the circular hole. Then go east and find the round boulder in the southeast corner. Push it left once, north twice, left once, north twice, then left four times. Push it down once, then you can push it left past the first boulder that you pushed into the hole. Then push it north and roll it into the circular hole to the right of the shrinking portal. Finally, push the third boulder to the right and climb down the ladder.

In the cave, go south and then west. Push the northernmost block to the left, then push the southwest block to the left. There is now a block northwest of the one that you just pushed. Put that one to the left, then push the block above you up, and before you move on, go directly south from the block that you just pushed, and push the block there downward.

Go north until you can go west, then go southwest to where there are two blocks, one above the other. Push the bottom of these blocks to the right. To the southeast, there should be a row of four blocks. Push the leftmost of those blocks down. There should now be three blocks to your right, and one block above those three. Push that upper block to the right, and the one below you down. There is now a block to the left of you. Push it to the left. Then you can go south and exit the cave.

Go east and go into the door.

Before you use the mushroom, stand to the north of the mushroom and use the Gust Jar to get rid of the pots across the gap. Then pull the mushroom south, and let go of the directional pad to go across. Go north and down the stairs.

If you need bombs, go to the northeast corner and push the left block up and the right block up, and push the middle block to the side, then break the pots to find bombs. Then go south and put down a bomb, then press R to pick it up, then press R to throw it. It should explode on the switch and extend the bridge. Go south, then pick up the pots to find rupees. Then go south and exit the cave, then go west and go through the door to reach another cave.

Push the round boulder down once, left twice, down twice, left three times, up once, left once, up once, and left into the round hole. Push the totem upward, then go down the stairs.

Push the southernmost block left, and push the one above you up. Then go to the left where there are two blocks in a column, push the upper block to the left. Open the chest to get a blue Kinstone piece. Go southeast and exit the cave.

Outside, shrink and enter the Minish path. Make your way west through the path and go through the door at the end.

Melari's Mines

The Minish in this area may have Kinstones to fuse. Make your way around the area and talk to the big Minish at the end to meet Melari. There will be a cutscene. Go west and talk to the Minish guarding the door, then go through.

Grow back to normal size, and check the gravestone to reveal another symbol. Then go north and enter the Cave of Flames.
