<P> Snotlout in the books, though very similar in personality, would never dream of becoming friends with Hiccup and actually bullies him . In the films he is Hiccup's friend, although not an especially close one; he is rude and competitive, but he knows and accepts that Hiccup will one day be chief . In the books, he is Hiccup's cousin and possible heir to the Hooligan tribe; some of his animosity with Hiccup is his desire to prove that he'd make a better chief . In the books, Snotlout has a monstrous nightmare named Fireworm . In the films he also has a monstrous nightmare, but it is named Hookfang . </P> <P> The name "Fireworm" was transferred to an entire species of small and flammable dragons in the films . </P> <P> Audio CDs, have also been made to accompany How To Train Your Dragon, made by Cressida Cowell and narrated by local Scottish actor David Tennant . Tennant also plays the voice of Spitelout, Snotlout's father, in the films and as well as in DreamWorks Dragons . </P>
