The Steam Team are about to go on their family vacations when they receive a call from Joe. Once again, there is trouble in one of the fantasy worlds! A crack has been found in a map in the Hall of the Seven Roses. The Discovery Kids go to the Crystal Kingdom where a dragon has been wrecking havoc all over the world. He has been transforming all of the precious gems into stone and leaving one path of destruction wherever he goes. Can the kids figure out why the dragon is destroying the Crystal Kingdom and stop him before it is late?
