Go to where you woke the guy up using the cucoo, outside the entrance to the castle; it's outside the area where you have to sneak through hiding from guards to meet princess Zelda. There should be a tree straight down from where he was. Play the Song of Storms in front of it and a secret grotto will open. Drop down into it. There will be a couple walls you can bomb, and inside one is a gold skulltula. Kill it, then make sure you are close to the platform that takes you out of the grotto. Use your boomerang to grab the token and before it gets back to you, backflip onto the platform. You will be given credit for collecting the token, and when you go back down, the skulltula will still be there! You can repeat this over and over and get an infinite amount of gold skulltulas.
