This level isn't that hard. If you have watched KOTCS, you should know what to do. If not, then you first escape from the Ugha (Do the same as you did in the boulder scene, those of you that have the first game). After that, you need to grab a bazooka lying nearby and shoot the stone faces only. Next, you have to run down the stairs because they are going back into the wall. Then, switch to Oxley, take out the Skull, and put it where the arrows point. After this cutscene, you must battle the skeleton that you just put the Skull on. When its hearts are gone, the level is done.
