From DreamWorks Animation comes a surprising tale about growing up, finding the courage to face the unknown…and how nothing can ever train you to let go. What began as an unlikely friendship between an adolescent Viking and a fearsome Night Fury dragon has become an epic trilogy spanning their lives. When the sudden appearance of a female Light Fury coincides with the darkest threat their village has ever faced, Hiccup and Toothless must journey to a hidden world thought only to exist in myth. In this last chapter, Hiccup and Toothless will finally discover their true destinies, and dragon and rider will fight together to protect everything they've grown to treasure.Bonus Content:Two Shorts: Bilby and Bird KarmaAlternate Opening with Intro by Writer/Director Dean DeBloisDeleted Scenes with Intros by Writer/Director Dean DeBloisHow to Voice Your VikingCreating an Epic Dragon TaleHow I Learned from DragonsBrave Wilderness Presents: Nature + Dragons = AwesomeThe Dragon Sheep ChroniclesA Deck of DragonsGrowing Up with DragonsThe Evolviong Character Design of DragonsDrawing DragonsEpic VillainAstrid's Whole Dragon Trilogy in 60 SecondsWelcome to New BerkFeature Commentary by Writer/Director Dean DeBlois, Producer Bradford Lewis and Head of Character Animation Simon Otto
