Needle Rock Isle gets its name from the tall, narrow rock pillar in its center. You can accomplish several tasks here.
Piece of Heart #22
Use a Hyoi Pear to take control of a seagull, then fly to the very tip of the needle and bump the switch there to activate it. This extinguishes the fire that surrounds the chest on the island, which contains Piece of Heart #22. Defeat the Kargorocs before attempting this.
Silver Rupee (via Treasure Chart #28)
Find and open Treasure Chart #28 (found at Horseshoe Island [A7]) to pull a chest from the Great Sea near Needle Rock Isle. The chest contains a Silver Rupee.
Triforce Chart #3
Three Warships are northwest of Needle Rock Isle, one of which is gold. Bomb all three and then use the Grappling Hook to pull the treasure up from the rings of light they leave behind. The wreckage of the two regular Warships yields a purple and an Orange Rupee, and the golden Warship gives you Triforce Chart #3.
Orange Rupee (via Secret Cave)
Melt the block of ice on the island to reveal a hole. Drop into it to enter a Secret Cave. Light six torches using Fire Arrows to reveal a chest with an Orange Rupee.
Here are the whereabouts of the six torches:
- Next to the entrance
- High on the ship to the left of the entrance
- High on the ship to the right of the entrance
- On the other side of the wooden railing in front of the entrance
- On the deck of the ship in the distance ahead of the entrance
- High on the crow’s nest of that ship
