I'm playing the iPhone, and I have only one golden hat left to complete the game. It's in hogsmeade, and I suppose I should buiild a SNOWMAN for it, 'cause I've got a hat, a nose, and some coal - BUT I CAN'T BUILD IT!!!! Help!!!! I've already put the two big snowballs on top of each other. But no matter how I try, I can't find a way to complete it. Its the only thing I have left to do!
