Ruffnut, Snotlout, Astrid, Fishlegs and Tuffnut, are all in dragon training with our hapless hero Hiccup in How to Train Your Dragon. In dragon training, young Vikings learn the art of killing dragons. Each dragon type has a whole different set of deadly quirks and characteristics to look out for, so dragon training is not for the weak of heart. The Vikings' greatest goal is to locate the dragons' nest and eradicate their sworn enemies forever.
