Dragons: Gift of the Night Fury

It is the first winter holiday on the island of Berk since the war between dragons and vikings was ended by the heroic efforts of Hiccup and Toothless. The vikings are looking forward to enjoying a peaceful holiday for the first time ever, but the dragons inexplicably decide to fly away, causing everyone to panic. It's up to Hiccup to find the answer and to save the day once again.
