Point to nuts appearing mottled (6)
I believe the answer is:
spotty
'mottled' is the definition.
(thesaurus)
'point to nuts' is the wordplay.
'point' becomes 's' (South).
'to nuts' becomes 'potty' (I've seen this before).
's'+'potty'='SPOTTY'
'appearing' is the link.
(Other definitions for spotty that I've seen before include "Covered in rash" , "Suffering from acne" , "Inconsistent" , "Freckled" , "Pimply or covered with dots" .)
