"I'm fine," replies Muir, staring up at Stormfly too. The Deadly Nadder is a new one on him, and looks very interesting, not to mention highly deadly...<br/><br/>(Fun fact: While Astrid never starred in the book series, Stormfly did. In the books, she was a 'rare norse-speaking mood dragon', which change colour depending on their moods and whether they're lying. And trying to ride her in the book series would have been nigh on impossible, given that she was small enough to fit in a backpack!)
