Bigfoot's kin (4)
I believe the answer is:
yeti
'bigfoot's kin' 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 "Feared creature" , "Mythical Himalayan beast" , "highland inhabitant" , "Mythical humanoid" , "Creature perhaps" .)
