A1: Well first you have to mount Legna and land on the casket. Then you have to jump and press triangle, to hit it. then you have to mount legna, and go hide behind the red piller. after the blast you get on legna right away and hit the casket. but you only have 5 seconds to hit it, which sucks. then you have to keep doing that with the different colors of the pillars. they always go in the same order, thank god. you only have 15 seconds to hide, and 5 seconds to hit the bone casket again. it is really hard, and I havnt finished it yet. :( you have to hit it 5 times total to win. I hope this helps. good luck :)
