Ah! Keep smacking him, i'd recommend Peter or Edmund, till you get what looks like a button w/ one of the four on it, then have that Pevensie walk up to the ogre and press a, the ogre should then pick up the Pevensie(i think it's Edmund) then you have an opportunity to hurt him!You have to get his life down a quarter of the way,or it goes back up. If you do this successfully, he'll throw Edmund down(I THINK!!!either that or he keeps hold of him). Hit him more till you get the pic w/ the Pevensie's face above him again, then use that particular pevensie again. Once again he will be distracted and you have to get his life down a quarter of the way. You have to keep repeating this till you get Edmund, Peter and Lucy grabbed onto him, then use Susan to finish him, using melee attacks. I'm not sure if I covered that in depth, but if not say so!
