The Colossus is a great place to relax. Unfortunately, you don't have time to relax. A stone wall surrounds the Colossus. Avoid the Leevers which come out of the sand and attack. Find a small crack in the wall between two palm trees. Bomb it to reveal the entrance to the final Great Fairy Fountain. From this fairy, you will receive Nayru's Love. Nayru's Love is a protective shield that surrounds Link when the spell is cast. The spell uses a lot of magic so watch your meter. It helps to use Nayru's Love when fighting the Iron Knuckles in the Spirit Temple. You will thrown back by the force of their hit but you will not sustain any damage. In the Colossus, you will find a dried up pond. Stand on a stone near it and play the Song of Storms. The pond will fill will water and Red Fairies will appear. That's all for the secrets here. Head for the Spirt Temple which is marked my the giant Sphinx.
