|“||My aunt Snaggletooth died of Vorpentitis, and it's a nasty way to go.||”|
|— One Eye in Book 4|
Snaggletooth's nephew, One Eye, tells the story that she died of Vorpentitis, an unpleasant illness afflicting both humans and dragons. It is caused by the sting of a Venomous Vorpent. Her death from this disease inspired One Eye to help Hiccup in his quest for a cure, despite his animosity toward humans.
Though no description is given for Snaggletooth, she is a Sabre-Tooth Driver Dragon and therefore most likely white in color with long fangs and a tiger-like jaw, as with the others of her species.
