Firstly, let us catch up on Goddess Cube chests.
Treasure Chest 1
Our first chest is found to the northeast of Skyloft and northwest of Bamboo Island. You’ll need to land on the lower ledge and swim through the water tunnel to the other side. Spin attack to climb up and reach this Heart Medal!
Treasure Chest 2
Our second chest is found southwest of Skyloft and northwest of Fun Fun Island. It is on the smaller half of the island. Go to the edge to some vines, then climb to the Life Medal within the chest!
Treasure Chest 3
You’ll love our third chest. This one is found within the Bazaar in Skyloft and contains a Gold Rupee!
Treasure Chest 4
Chest 4 is found in the general area of the second chest above. You’ll need to land on the small island half and Clawshot to the Clawshot target above the gate to reach the Potion Medal. Quite a few medals so far, eh?
Treasure Chest 5
Our final chest is found in Skyloft, atop the waterfall. You’ll need to use the Clawshots to get Heart Piece 6.
When done, head to the far northwestern corner of the map and into the Thunderhead. Continue northwest to the Isle of Songs.
Inside the Thunderhead
Just land on the Isle of Songs and go into the tower - the bridge is already made. Inside, go forward to the circular design and stand on it. Again, use a Skyward Strike to hit the crest across the gap. Afterwards, a scene ensues and you’ll learn the fourth of the harp songs, Din’s Power.
Our next destination is Eldin Volcano. Exit the tower and dive off of the island, then proceed southeast to exit the Thunderhead. Fly east to the red beam of light, and descend within it.
