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 wordplay.
'animal endangered' becomes 'panda'.
'about' means one lot of letters goes inside another.
'the last in' indicates one should take the final letters.
'in' means one lot of letters goes inside another.
'organised slaughter' becomes 'cull'.
The final letter of 'punjab' is 'b'.
'panda' enclosing 'b' is 'pandba'.
'pandba' put into 'cull' is 'CUP-AND-BALL'.
