Confused wee creature (3)
I believe the answer is:
ewe
'creature' is the definition.
(female sheep)
'confused wee' is the wordplay.
'confused' indicates an anagram.
'wee' with letters rearranged gives 'EWE'.
(Other definitions for ewe that I've seen before include "A palindromic sheep" , "Source of milk" , "One looking sheepish" , "She'll provide material to knit" , "21a [SHEEP]" .)
