hey, if you have two children climbing mountains, why do they have hammers? How do hammers help you climb mountains? I would understand ice picks, which would probably be better weapons than a hammer. So why the hammers? Also, in a completely frozen area which they live in, how could they have obtained hammers made of wood? If that was possible, igloos would be made of wood.
So I repeat, why hammers instead of ice picks? And don't say "it's just a game". I want valid reasoning here.
