Fancy treats stopped (2,4)
I believe the answer is:
at rest
'stopped' is the definition.
(I've seen this before)
'fancy treats' is the wordplay.
'fancy' is an anagram indicator.
'treats' with letters rearranged gives 'AT REST'.
(Other definitions for at rest that I've seen before include "Not moving, free from anxiety" , "Free from trouble or anxiety" , "Immobile" , "Stopped" , "calm" .)
