Creator of Heffalumps and Woozles (5)
I believe the answer is:
milne
'creator of heffalumps and woozles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for milne that I've seen before include "He wrote stories for his son, Christopher Robin" , "Writer of Winnie the Pooh" , "Pooh's creator" , "A.A. -, Pooh author" , "AA man" .)
