Pal of Pooh and Piglet (6)

I believe the answer is:

eeyore

(Other definitions for eeyore that I've seen before include "Pooh's sad friend" , "A. A. Milne donkey" , "Pooh's pessimistic companion" , "Milne's depressive donkey" , "Piglet's sad friend" .)

I've seen this clue in The Times and The Sunday Times.
