On the Final Night, with less than an hour remaining, head to the Clock Tower. The four Giants will appear and hold back the moon. You will then be transported inside the moon. Here, you'll find a surreal landscape with five children playing. Each child represents a dungeon and will ask you to give them your masks. Giving them masks will lead to mini-dungeons that test your abilities as different forms of Link. The more masks you give, the easier the final boss fight will be.
