Like in the original game, the Skulltula Glitch is still in the game.

Go into Hyrule as a child, climb the vine at the beginning. Go past the guards, and jump into the water and get out at the first turn. Go to the tree, and place the Song of Storms. Bomb the doorways, and find the skulltula. Use the boomerang, and kill the skulltula. Now the tricky part, throw the boomberang and hit the skulltula but after you throw your boomerange do a backflip into the exit. If you get the skulltula before getting into the portal, then you failed. If you got it while you where being transported out, then you accomplished the cheat. If you continue doing this correctly, you can get a infinite amount of skulltula's.
