Create a large, ghostly shark with shimmering frost-covered scales in pale blue and white. Its sleek body is adorned with jagged fins resembling frozen crystal shards. The shark’s glowing pale blue eyes pierce the darkness. Its sharp, frost-tipped teeth glisten in the dim light. The environment should feel dark and eerie, capturing the shark's ghostly, cold presence as it swims through the deep, frigid waters. #ChristmasAdventure#
