'for roly-poly' is the definition.
The definition suggests a singular noun which matches the answer.

'food processor and receptacle' is the wordplay.
'food processor' becomes 'gut' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'receptacle' becomes 'bucket' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gut'+'bucket'='GUTBUCKET'

'needed' acts as a link.
