Beneath the Graveyard

 in is a large, disjointed grotto that serves as the final resting place for the royal family of Ikana Kingdom.

Overview
The graves can only be opened using the Captain's Hat, a mask acquired after defeating Skull Keeta in a race and subsequent battle. It allows Link to converse with Stalchildren throughout Termina, although it is only necessary to do so in the graveyard itself. While wearing the Captain's Hat, they mistake Link for Keeta himself and ask whether they should continue guarding the gravesites.

Night of the First Day
The grave being patrolled on the night of the First Day is the only one that is necessary to open. The Stalchildren, who mistake Link for Skull Keeta while wearing the Captain's Hat, promptly follow his instructions and demolish a tombstone to reveal an entrance to the nether regions of the graveyard. Within this area, Link must battle an Iron Knuckle in order to release the imprisoned soul of Flat, one of the Composer Brothers. Flat reveals the inscription for the Song of Storms and asks that Link cleanse the soul of his cursed brother, Sharp, using the melody he has just learned.

Night of the Second Day
On the night of the Second Day, the Stalchildren will be guarding a different grave. Asking them to open it reveals another section of the cavernous areas beneath the graveyard. This segment contains many hidden enemies and traps that Link must uncover using the Lens of Truth. At the end of the grave lies another Iron Knuckle, which must be defeated to reveal a chest containing a Piece of Heart.

Night of the Final Day
The grave guarded by the Stalchildren on the night of the Final Day leads to an entirely separate location from the one accessed on the two prior occasions. This one has Dampé wandering inside it; he claims to be searching for the Royal Family's treasure. However, his torch has gone out, and he asks Link to guide him using his fairy. After a brief expedition which involves digging several isolated patches of dirt, the young hero and the gravekeeper uncover three blue flames that merge to reveal a Big Poe. Dampé flees in terror, leaving Link to battle the ghost alone. After its defeat, a treasure chest appears containing an empty bottle. Upon ascending the stairs at the end of the area, the gravekeeper can be found hiding under his bed, stricken with fear.
