The author who brought us Hiccup and his trusted dragon Toothless is visiting Newsround HQ this week.
Cressida Cowell's How To Train Your Dragon books have been hugely popular since the first one came out in 2003.
With movies, TV shows and toys, people all over the world have followed Hiccup's journey to becoming a hero.
We asked you to send in your questions and dragon drawings for Cressida.
Thanks for all of your fantastic drawings and comments! This page is now closed.
