When you are in the level Gates of moria eventually you run into a kraken. Heres how you beat it; It will attack you so you must deffend yourself (presing the B button), then it will raise a tentecual and put the tentucal back in the water. That tentucal is the one he will raise first. Go up by the same tentecal and get ready to attack is; when the kraken raises the tentecal attack it(by presing the A button). once you do that for awhile it will eventually die.
