Cute rear that wobbles, something wild (8)
I believe the answer is:
creature
'something wild' is the definition.
I can't tell whether this definition defines the answer.
'cute rear that wobbles' is the wordplay.
'that wobbles' indicates an anagram (I've seen 'wobbling' mean this).
'cute'+'rear'='cuterear'
'cuterear' with letters rearranged gives 'CREATURE'.
Can you help me to learn more?
(Other definitions for creature that I've seen before include "Human being or lower animal" , "Bird, beast or fish" , "Brute" , "Bird, beast, insect etc" , "Animal or person" .)
