This is a description taken from LEGO.com. Please do not modify it. (visit this item's product page) For more than a thousand years, the serpent guardian of the Shrine of the Golden Scarab Shield has appeared to be a mere sandstone statue. But at the command of the Pharaoh’s mummy snake charmer, the cursed Cobra springs to life and attacks anyone foolish enough to try to steal the treasure it guards. It will take all of an adventurer’s skill to escape the giant snake’s striking fangs and sinister coils!
