Stuck in the 3DS version. Battle of Pelenor is different than the console version. After playing as Gandalf and Pippin, you play as Legolas, Aragorn, and Gimli. I come across one of those huge elephants, but I get stuck there. It's standing still, not moving, and there are two archers in the top of it. I think I'm supposed to stand on this ledge and shoot the archers inside, but the wall blocks all my arrows. Been stuck for five hours and I'm nearly ready to quit. Any and all help would be appreciated immensely.
