LostWinds/The Second Memory Chest

Once you reach him, speak to Deo for a cutscene. Then, head left to the next screen and take the top left exit of this screen. Now, fall down to the left and slipstream burn the vines to the right. Head right, into the old mines.

Here, gust to the right until you reach a small switch on the ground. Hold and gust upwards to activate it, then head down, start the smoldering torch, and use it to burn the vines to the left.

Continue down, ignoring the pressure pad, until you reach a save point and a rock. Save if you want, then gust the rock back up to the pressure pad and head through the door to the left when it opens.

In this room, head down and activate the shrine like the other two you've already gained powers from. After a short cutscene, you'll gain the power of Vortex. Gust a circle around things to keep them afloat in the air, then gust them in a direction to send them flying with great force, to break down wooden doors and other things.

Head left and gust this strange ball near to the large crystal, then create a Vortex around the ball. It will resonate with the crystal, causing it to shatter and allowing you to continue left. There's a door here with a small crystal in it. Do the same thing, cause the ball to resonate with the crystal to open the door and open the path to the next room.

Here, there's a new enemy. A sort of...enemy crab. To be declared victor of this crab battle, gust it up into the air, then use a Vortex on it, followed by a swift gust into the ground, which will change it into a couple of Glorbs.

After that, head left, and eat the fruit if you need to. Then, cast a Vortex on to the rock and gust it downward into the cracked floor below. If done correctly, the floor will shatter. Head down now, and take the rock that you pass with you. Take care of the bird enemies and bring either the fruit or the rock with you. Strangely, the fruit can actually take down the wooden door ahead with the same type of Vortex move that you've been using on crabs and crack floors. Kind of weird if you ask me. Anyway, after you've Vortexed the door down, head right into the next room.

Jump down the hole in the floor and head right. Use the crab enemy (or the fruit) to blast the wooden door down with a vortex. Head up, and use the fruit to vortex the door down. Step on the pressure pad to the right, then gust the Resonance Ball down the trap door that opens. Head left, then down and to the right and take the fruit with you to break down another wooden door. You could go down and bounce the rock up for use with breaking the door but why, when you can BREAK HARD WOOD WITH SOFT FRUIT?

Anyway, head past the door and start moving up until you can go left to a pull-switch activate it ( and gust upwards), then retrieve the Resonance Ball and start heading up with it. Use it to break the crystal on the right (the room past the left one contains a totem if you need to know) then head right to the next room.

Kill the Glorbs, then use the Resonance Ball to break the crystals blocking your path. Keep it with you and head right, save, then use the ball to open the Crystal door. Afterwards, head right to the next room.

Pull the switch and head down. Use the crab enemy to break the wall to the right, then keep going right and step on to the right pressure pad. Slipstream burn the Poyak, then gust the seed upwards and to the left, above the other trap door. Then, step on the left pressure pad and the seed should fall down to you. Take it along and head back left.

When you can, gust up and to the right and keep going up until you reach a bit of soil, where you should plant the seed. Use it to gust yourself up and to the right, where you should head into the next room.

Start the smoldering torch and use it to burn the Poyak. Take it up with you and plant it in the bit of soil to the left, then use the new Poyak to gust up to the Resonance ball. Take it back down where you burned the first Poyak, then head right and use the ball to break the wooden wall with a Vortex. Use the Poyak here to gust it over the wall, then head over it yourself. Shatter the crystal using the resonance ball here, then head right and when you reach a dead end (watch for the crab), start Slipstream burning the torches until you can reach the plant on the left with a flame. Take the seed and take it where it can reach sunlight (the first patch of soil you burned a Poyak at in this room). Pick up the new plant, and use a combination of Slipstream and gust to reach the area in the top right. Head right here, and use three well timed gusts to the right to get across and head right into the next room.

Here, head all the way down to the pressure pad, lighting the torches along the way using Slipstream fire. Gust the rock onto the pad after stepping on it to open then door, then head through the open door. Use one of your lit torches to burn the vines with Slipstream flame, then head left into the next room.

In here, head left then up and to the right to enter a different point in the same room as before. Gust across to the pull-switch, activate it, then head down into the trap door that it opened. Leave the plant at first, and head right. This new enemy can steal the flower from you, so you should defeat it first. To do so, gust over it, and when it tries to bite you, cast a vortex around it then gust it into the ground. Kill the resulting glorbs, then go back to the plant and use it to slipstream up and to the right.

Finally, the second chest. Hold and gust upwards to open it. Afterwards, head right to wind up in the same room where the first chest was opened. From here, just exit the cave like last time and head back to Deo!
