In this film, when Valka first met a dragon rider on a Night Fury, she sent Clawlifter to grab him from above. Clawlifter grabbed the young boy as the Night Fury plummeted into the icy lake below them. Then, Clawlifter carried him to his mountain, right behind Valka. The boy attempted to train him. After that, it was revealed that the boy was none other than Hiccup--Valka's son.
