Duck fine among endangered bats in paradise (6,2,4)
I believe the answer is:
garden of eden
'paradise' is the definition.
(I've seen this before)
'duck fine among endangered bats' is the wordplay.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'fine' becomes 'f' (abbreviation).
'among' is an insertion indicator.
'bats' indicates an anagram (slang for mad).
'o'+'f'='of'
'endangered' is an anagram of 'gardeneden'.
'of' placed into 'gardeneden' is 'GARDEN OF EDEN'.
'in' is the link.
(Other definitions for garden of eden that I've seen before include "Genesis paradise" , "Home of Adam and Eve" , "holy plot?" , "Idyllic haunt" , "Scene in Genesis" .)
