Mythical Himalayan (4)
I believe the answer is:
yeti
'mythical himalayan' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yeti that I've seen before include "Himalayan wild man" , "Hairy Himalayan humanoid" , "mythical monster!" , "that you might find in mountains" , "supposed mountain creature" .)
