The soccer world is in mourning today. Paul the Octopus has passed away at his aquarium in the German city of Oberhausen. He apparently died of natural causes. Paul predicted the outcome of all of Germany's matches in this year's World Cup and Spain's win in the final.Before every match, he'd be shown two clear plastic boxes. Inside each was a mussel and a country's flag. Paul picked the right one every time. BBC's Matt Cole has more.
