Fairy tale creature (3)
I believe the answer is:
elf
'fairy tale creature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elf that I've seen before include "Dwarf" , "Naughty child" , "Mischievous fairy No.2" , "'Pixie, imp (3)'" , "Magical being" .)
