Animals wrecking a nice dish I put out (8)
I believe the answer is:
echidnas
'animals' is the definition.
The answer is an example.
'wrecking a nice dish i put out' is the wordplay.
'wrecking' indicates anagramming the letters (I've seen this in other clues).
'put out' indicates named letters should be taken away.
'a'+'nice'+'dish'='anicedish'
'anicedish' with 'i' taken away is 'ancedish'.
'ancedish' is an anagram of 'ECHIDNAS'.
(Other definitions for echidnas that I've seen before include "Spiny anteaters" , "Spiny mammals" .)
