Gobber: Today is about teamwork. Now, a wet dragon head can't light its fire. The Hideous Zippleback is extra tricky. One head breathes gas, the other head lights it. Your job is to know which is which. Fishlegs: Razor-sharp serrated teeth that inject venom for pre-digestion. Prefers ambush attack, crushing its victims... Gobber: Will you please stop that?!
Gobber describing the teamwork as being the order of the day and how to work on a dragon. Fishlegs reciting info about the dragon at the same time. Hiccup very annoyed asks Gobber to stop.
