Take off on brilliant new adventures in the frozen Viking ice-mines of Chilblain! In 'Snowmageddon', the dragons and riders of Berk set out to help a Viking settlement under seige, only to find the grizzled Chief Hagar Frostbeard doesn't take kindly to dragons! In 'Thaw Fleet', sudden melting snow means sleds are running too fast down the Ice Canal, causing big problems for the Vikings! Can Hiccup and his friends find a way to help the people of Chilblain?
