When Darkness Falls (3x4)

:

The riders finally find an island that will be perfect for an outpost. Unknown to them, a new species of dragon living on the Island, known as the 'Night Terrors', lives there too, and they ambush and scare Tuffnut. After the group traps the leader dragon they realise how much danger the rest of the dragons are in when Changewings begin attacking them. They suddenly realise that the Night Terrors, under the command of their Alpha, a white Night Terror, need to flock into a shape of a giant version of themselves or any other dragon they wish as a defense mechanism to scare off threats or predators. The dragon riders fight off the Changewings and free the leader. The leader then befriends the riders as the natural protector of them and the island.
