Game animal, endangered (about the last in Punjab) in organised slaughter (3-3-4)
I believe the answer is:
Here is my best explanation:
'game' is the definition.
'animal endangered about the last in punjab in organised slaughter' is the subsidiary indication.
'animal endangered' becomes 'panda'.
'about' is an insertion indicator.
'the last in' says to take the final letters.
'in' is an insertion indicator.
'organised slaughter' becomes 'cull'.
The last letter of 'punjab' is 'b'.
'panda' placed around 'b' is 'pandba'.
'pandba' inserted within 'cull' is 'cupandball'.
