Give Telma’s bar another visit and read the map on the table again to learn the whereabouts of Rusi. You’ll discover he’s hanging out in north Faron. Warp to north Faron woods and to find him just past Trill’s Shop on a small incline. Speak to him as human Link to learn about an ancient temple on the other side of the gorge. Grab the golden cucco he provides and then jump to the platform ahead – don’t worry about falling, the cucco will slow your decent letting you cross the gap.
Continue to the next platform and then into the short tunnel. Rotate the bridge with the Gale Boomerang and then cross onto it with the Cucco. Rotate the bridge once again and then float across the gaps, timing your jumps to avoid the swinging log, and enter the Sacred Grotto ahead.
It looks like the Skull Kid is back and annoying as ever. Dispose of his Skeleton minions with your spin attacks, and then search the cavern for the kid. Listen for the trumpet and look for the light given off by his lantern to find where he is. Make sure you have some arrows handy (defeat the enemies if you some refills) as one of his hideout’s is atop a tree. After three hits, he’ll retreat to an area with several platforms. When he appears, shoot him with an arrow to force him to a different platform. During each phase, he’ll unleash several enemies to hunt you down, but if you shoot the skull kid quick enough, the baddies won’t even be a factor. Once he’s been pelted by three arrows, he’ll reveal a secret entrance leading to the Temple.
Push the block out of the way and then drop onto it and follow the path into the area below and proceed north to the pedestal where you obtained the Master Sword. Strike it with your Sword to make a statue disappear near the entrance, which leads into the Temple of Time.
As you head toward the door, you’ll be ambushed by five Twilight creatures. Defeat them with Human Link’s spin attacks, or Wolf Link’s Energy Shield and proceeds back up the path you came from and enter the Temple of Time.
Proceed through the temple and strike the pedestal at the end once more with your sword to reveal a stairway leading up to the stained glass window and go through the door beyond.
