The game takes place a year after the movie's ending. After defeating the Red Death, as a form of celebration, the Tribe has created a festival which they call "Thor'sday Thursday". On this festival, the Vikings always hold a dragon tournament and all of the teenagers are encouraged to participate with the dragons that they've trained. Players can play as either Astrid or Hiccup, the main human characters of the film. (Although Hiccup has his leg, he lost it in the film.) Before entering the actual tournament, players must use the training grounds to train their dragon to fight. After entering the tournament, they must defeat all of the other opponents and, eventually, win the dragon tournament (by defeating Snotlout Jorgenson) and be named dragon-taming champion. The player can create and customize their own dragon in the dragon den, where they also take care of the dragons, feeding it food the players have found all around Berk, the setting of the series.
