In which we learn that Hookfang is a better physicist than Hiccup… The riders take trust falling to extremes and teach us something about the physics of falling (and landing). The resident curmudgeon (Mildew) tries again to rid Berk of dragons after they are accused of boot theft, vandalism, and blowing up the armory; in the process, he becomes a much more formidable villain. Hiccup tries defending the dragons with a DUMB solution. Gobber tries his hand at being a cobbler (our word of the day). The writers try their first two-part episode of the series, but forget to tell the title.
