Hiccups and Astrids kids Nuffink and Zephyr HATE dragons... one day the two were put playing with their friends when a bunch of dragons fly in... all from the hidden world like their running from something... even the Bewilderbeast shows up...

Nuffink: Zephyr get behind me! They'll hurt you!

Zephyr: no! Ima get mom and dad! runs to get Hiccup and Astrid
