Bringing back a bear found around Lima is fair game (4-2)
I believe the answer is:
hoop-la
'fair game' is the definition.
(I've seen this before)
'bringing back a bear found around lima' is the wordplay.
'bringing back' says the letters should be written backwards (I've seen 'bring back' mean this).
'bear' becomes 'pooh' (Winnie the Pooh).
'found around' indicates putting letters inside.
'lima' becomes 'L' (phonetic alphabet: alpha, bravo, charlie etc.).
'a'+'pooh'='apooh'
'apooh' going around 'l' is 'alpooh'.
'alpooh' reversed gives 'HOOP-LA'.
'is' acts as a link.
(Other definitions for hoop-la that I've seen before include "Throwing fairground game" , "Game in which rings are thrown over objects in order to win them" .)
