Legendary Himalayans (5)
I believe the answer is:
yetis
'legendary himalayans' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yetis that I've seen before include "Mythical creatures" , "fantastic beasts" , "Mountain monsters" , "Rarely seen group of creatures" , "Abominable snowmen" .)
