FIFTH COLOSSUS

You won't be able to get the attention of this Colossus just through whistling, so that means you have to use the other way of getting something's attention from a distance, your bow. You're still too far away at this point so note the cracked ground right beside where you start, drop down here and you'll land in the water. From here you want to start swimming east, with a very slight southeast tilt. In between two of the large stone structures you should find a few platforms which protrude only slightly out of the water. Swim up beside one of these platforms and hit the triangle button to jump out of the water and up onto it.

Equip the bow and hold the square button to charge up your shot, then hold the L1 button to automatically look at the boss, and fire. This will definitely get his attention and he takes off from the perch and begins to fly around (if he flies down near you so just part of his wing is about to clip you, drop in the water to be safe.) Now the boss will begin attacking, especially if you keep shooting arrows at it. The boss' one main attack is to dive out of the sky head first directly at you, and obviously this is going to be the only means you have to get on him.

Keep firing arrows from your platform as the boss flies through the sky. Remember the age old Space Invaders logic of shooting not where he is, but where he is "going to be" since the arrows have travel time. Eventually when the boss gets mad enough it will swoop down toward you, and this is your chance. There is fur on the boss wing where it meets the body. You need to wait until the timing is right, then jump forward at this fur and hold the R1 button. If all goes well then you are now holding on. I forgot to mention, if the boss keeps swooping but never close enough to grab on, try jumping over to the next platform. The boss isn't so much swooping directly at you as he is swooping between the two large stone structures, so you can move to the next platform and try from there.

This is where it starts to get interesting. Unlike other bosses you cannot simply take a break on any flat surface, there is strong wind resistance that will push you along and blow you off if you aren't careful. It's still possible to let go for a short period of time, but you have to make sure the boss is moving straight and calmly, and grab hold again at any indication of change. We'll begin with the two more difficult symbols to hit, because you are closer to those ones.

At the tip of each wing there is a symbol and you will have to reach them. In the middle of the wing there is no fur so that's going to make it more difficult. What you need to do is hold onto the fur of whatever wing you are on, and wait until you get a few seconds of calm. At that point quickly let go and run like mad across the wing in an attempt to grab the fur near the tip before the monster starts to flap its wings again. Once you have hold of the fur you're relatively okay. The symbol is right here below you, equip the sword and you will see it in the middle. You need to charge up one single attack and stab down into the wing. This symbol and the one on the other wing can only take one charged up hit before they disappear so after stabbing once, get back to the main body. This is good because after the stab, the monster flips upside down and you lose a hell of a lot of grip strength. It's no big deal if you fall of course, you'll lose a lot of time, but you can get back up always the same way you did before. Either way you now need to do the exact same thing, except you must get to the tip of the other wing this time.

Finally once the symbols on both wings are gone, there is one more remaining. This symbol is at the very tip of the tail. What you need to do is get onto the main body and then when things calm down a bit, let go. Begin running as fast as you can down the body toward the tail. If he starts to turn at any point, simply grab on wherever you are. When you eventually reach the tail there is a large symbol there which you can start stabbing like mad. It's the last one, so it will kill the Colossus.
