this is a trick i learned to get more than 100 gold skullates:
what you do is you go to the castle as a kid and play the song of storms near the tree by the fence(the tree that is visable right after you get out of the stream to avoid the gaurds) the one before you get to Talon, play the song of storms and open the hole, drop down and find the gold skullate in it, now this is tricky, kill it, but dont grab the coin yet, stand right in front of the beam that will bring u back to the surface, and face the token, lock on and use ur boomerang , right as the boomerang hits the token do a back flip onto the beam, and youll be back on the surface, go back down and the token is still there, but it still counts as one, do this as many time needed, its fun to get 101 of them, try it, its cool.
