Fact: Toothless got a complete makeover from his image and personality in the book to his role in the full movie and the book’s author approved of the changes.
The red and green dragon featured in the book is close in size to the Terrible Terror breed of dragon or a small cat. The name Toothless is given to him by Hiccup when he loses the one tooth he’s grown, after a time of having no teeth at all. The producers felt that the dragon should be large enough to be a mount, adding to the story and the impressive animation.
Cressida Cowell, author of the book, agreed to the changes. Thus Toothless became a Night Fury, the rarest breed of dragon with traits like speed, intelligence, and stealth. Resembling an inspired blend of cat, horse, bear, dog, and salamander, the dark black Night Furies have the largest wing-to-body ratio of all dragons.
The producers kept the dragon’s name and changed the story on film, showing his teeth retracting into his jaws for protection while he breaths fire. Various track of sounds are combined to make his sounds, including recordings of elephant seal pups from The Marine Mammal Center in Sausalito, CA.
