Dragon Eye of the Beholder Part 2.Hiccup goes to save the other riders but discovers that cage is 'dragon proof'. After much effort they finally get it open and Hiccup is able to retrieve the 'Dragon Eye' from a distracted Dagur. Back on Berk Gothi tells them that the key to unlocking the 'Dragon Eye' is a tooth from the Snow Wraith (a dragon that detects body heat as a form of sight). The riders and Gothi travel to Glacier Island to retrieve the tooth, which later reveals that the device is some sort of projector showing maps and other information. Meanwhile, Gobber takes Gothi's place as the village healer, however he is far from good at it!
