From Zelda Wiki.org
There is a private luxury house that can only be entered if you have the
Cabana Deed which
Mrs. Marie gives to you after giving her 20
Joy Pendants. Once you have obtained the deed, you may enter and the island's name will change to Link's Oasis (or the player's name). Inside the house you will see a lever, use your
Grappling Hook to pull it down and remove the flame in the fireplace, this goes down into the cabana basement. In the basement, take the first ladder to your right, once you're down take the passage on the right side and take the next ladder up. Hit the two plungers with your
Skull Hammer and proceed to the next ladder. If you want to, crawl through the tunnel to the left to obtain 100 rupees then go into the other tunnel to the next ladder. Go to the brown hole next to the plunger and descend into it, once down there you will meet two
ReDeads then crawl into the tunnel. In the next room play the
Wind's Requiem on the wind mark to obtain a chart to one of the
Triforce Shards.
It also involves a minigame run by the door/butler, which involves rearranging tiles to create pictures. It is considered a great source of Rupees.
