100+ Gold Skulltulas

As child Link, with the boomerang and bombs, go to Hyrule Castle.Make your way past all the guards until you get to the area right outside the castle, next to the moat.There is a large tree located here, stand next to it and play the Song of Storms to uncover a secret grotto.Inside the grotto are bombable walls, bomb these until you find the one with the Gold Skulltula behind it.Kill the Gold Skulltula so it's token appears.Stand close to the "warp pad" that takes you out of the grotto, with your back to it, facing the token.Throw the boomerang at the token. When the boomerang is about halfway back to you with the token, do a back flip onto the 'warp pad'.You should land on the 'warp pad' and then straight away catch the boomerang, the blue text box that tells you you have collected a token will appear and then disappear as the screen fades out.As long as the blue square at the end of the text box - that indicates the end of the message - does not appear, the glitch will work.You will now appear back at the Castle, look at the 'Quest Sub screen', your Golden Skulltula total should have gone up by one, go back into the grotto and the Golden Skulltula will still be there, repeat this to get a maximum of 255 Skulltula tokens.
OR: As child Link go to the entrance to Gerudo Valley from Hyrule Field with the boomerang, bombs and Din's Fire, in this area there is a circle of small stones.Throw a bomb into the circle to uncover a grotto entrance, go into it.In the grotto there is a cow behind some spider webbing, use Din's Fire to burn away the webbing.Behind the cow on the wall is a Golden Skulltula. Put yourself about halfway between the Skulltula and the "warp pad".Kill the Golden Skulltula.Throw your boomerang at the Golden Skulltula token and start stepping backwards towards the "warp pad", make sure you do not step onto the "warp pad", stop just before you reach it.Again, when the boomerang is halfway back with the token, do a back flip onto the "warp pad".You should land on the "warp pad" and then straight away catch the boomerang, the blue text box that tells you you have collected a token will appear and then disappear as the screen fades out.As long as the blue square at the end of the text box - that indicates the end of the message - does not appear, the glitch will work.You will now appear back in Hyrule Field, look at the 'Quest Sub screen', your Golden Skulltula total should have gone up by one, go back into the grotto and the Golden Skulltula will still be there, repeat this to get a maximum of 255 Skulltula tokens.Note that this can also be done in the secret grotto located under the tree to the left of the stairs leading to Kakariko village, it may also be able to be done in other grottos, if you find one where it works tell me!
