A Day in the Limelight: After several chapters centered around the triplets, here we focus on what their parents (and previous protagonists) Hiccup and Mirabel are up to without them.
Amusing Injuries: Apparently his test of the Dragon Fly I ended with Hiccup in a full-body cast, requiring a five-course meal of Julieta's food to heal completely.
Whole-Plot Reference: Hiccup's disastrous flight-suit prototypes, all of which the rest of the family views with skepticism, are a reference to the Dreamworks Dragons episode "The Next Big Sting".
