Bird’s Peak Rock is divided into two isles—one covered in grass that you can walk onto and another a short distance away that’s made of several pillars of rock. Many Kargorocs make their nests in the high peaks of the second isle.
Blue ChuChu
Find a wooden peg sticking out of the wall above the steel door on the island. Use the Grappling Hook to latch onto the peg, then pull yourself up to a tiny area above the steel door. Defeat the Blue ChuChu there for a Blue Chu Jelly.
Triforce Chart #2 (via Secret Cave)
To get this Triforce Chart, you must open the steel door on the grassy isle. Do this by activating each of the white, diamond-shaped switches in the Kargoroc’s nests atop the pillars of rock in the distance.
Start by pulling out the Hero’s Bow and picking off most of the Kargorocs nesting on top of the rock pillars. Once you’ve dealt with them, use a Hyoi Pear to take control of a seagull and fly into each switch. The steel door opens when all are activated. Drop into the hole just beyond the steel door and acquire Triforce Chart #2 from the Secret Cave below. For more information, refer to the walkthrough (p. 230).
Silver Rupee (via Treasure Chart #36)
Find and open Treasure Chart #36 (found at Ice Ring Isle [E6]) to pull a chest from the Great Sea near Bird’s Peak Rock. The chest contains a Silver Rupee.
