In the novel The Neverending Story, a nimbly is a Fantastican creature that looks like a rabbit but has feathers instead of fur.

Nimbly was also used as the name of a character in the second movie, The Neverending Story II: The Next Chapter. This Nimbly is a large bird creature who works for Xayide and falsely befriends Bastian, but has a change of heart after seeing one of Bastian's memories, in which his mother tells him that we are all part of a neverending story even if we die, and helps him in a desert, telling him that Atreyu and Falkor are in the ruins of Silver City.
