Tinkerbell tried to separate Wendy from Peter by using any and every prank at her disposal. When none of them succeeded, she decided to take stronger measures. Perhaps a certain pirate captain would be willing to lend a hand... or a hook.

Tinker Bell (Tink for short), is a fictional character from J. M. Barrie's 1904 play "Peter Pan" and its 1911 novelization "Peter and Wendy". Tinker Bell was described as a fairy who mended pots and kettles, like an actual tinker. Her speech consists of the sounds of a tinkling bell, which is understandable only to those familiar with the language of the fairies.
Though sometimes ill-tempered, spoiled, jealous, and vindictive, at other times she is inquisitive, 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.
