'a crazy bounder' is the definition.
The definition suggests a singular noun which matches the answer.

'crazy bounder' is the wordplay.
'crazy' becomes 'march' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bounder' becomes 'hare' (I've seen this in another clue).
'march'+'hare'='MARCH HARE'
