As far as I know, this colossus doesn't have many attacks, the only real chall-
enge is getting on it so you can reach its vitals. The only attack that I am
aware of is when you are riding under the colossus, it will curve its body in
an attempt to hit you with one of its multiple fins. Once you regain control of
your character, ride Agro towards the flying colossus. When you have reached a
good speed, hold R1 and press up on the left analog stick to stand. Equip your
bow and shoot the white bulbs underneath the colossus. When you successfully
punctured them all, the colossus will lower to the ground, allowing you to grab
hold of it. Ride alongside the wounded colossus with Agro and get as close to
its wings as you can. Jump and grab onto the little ridges on the colossus'
wing. If you are having trouble grabbing onto its wing, try to either cut him
off with Agro and jump on, or stand in its path and as it flies by jump and grab
on. Do not ride along side it, he is too fast. The Colossus will fly back into
the air, now you need to get on its back. When the wing is straight, loosen
your grip, run and jump onto its back. Grab hold of its fur. The symbols are
behind the creature's fins. Run behind one of the fins, grab hold of the colo-
ssus, charge your strength and stab the symbol.
Once you have struck the vital point a couple of times, it will disappear.
The colossus will most likely retreat into the sand, and once it emerges again
its bulbs will be refilled. Simply repeat what you did previously, shoot the
white bulbs, grab onto the creatures wing, get onto its back and move to a
different fin. There are three different vital points, each one behind one
of its fins. You will probably need to puncture its bulbs and jump on its back
three times until you can reach all of its vital points. Its fin will fold down
and cover the last vital point if you reach it before the creature returns to
the sand. Hold L1 so you know where it is while it is in the sand, this way you
will be ready for it when it emerges once more.
