Though sometimes ill-tempered, spoiled, jealous,[2] and vindictive,[3] at other times she is helpful and kind to Peter. The extremes in her personality are explained in the story by the fact that a fairy's size prevents her from holding more than one feeling at a time, so when she is angry she has no counterbalancing compassion. Fairies can enable others to fly by sprinkling them with fairy dust (called "pixie dust" in the Disney films, and presented as "starstuff" in Dave Barry and Ridley Pearson's novel series).[4] At the end of the novel it is implied that Tinker Bell has died the year after Wendy and her brothers left Neverland, as fairies have very short lives, and Peter has no memory of her at all.
