At the Graveyard, you have to find the Head's brothers. There will be alot of fake heads that are wanna bees. Now,from the begging you'll have a choice to go straight or go left. Go left and press square on the one on the left. Ok,now keep on going that way, and then you'll find 2 more heads. Choose the one on the left. Finally, you'll find three heads on the hill. Stand in front of the heads so that you see a backwards triangle. Choose the head in the upper left. If you do this
correctly, lights will come on, and a huge Castle will come out of the ground.
