Bambi, for example, comes back for plant (4)
I believe the answer is:
reed
'plant' is the definition.
(reed is a kind of plant)
'bambi for example comes back' is the wordplay.
'bambi for example' becomes 'deer' (the Disney character Bambi is an example).
'comes back' says the letters should be written backwards.
'deer' backwards is 'REED'.
'for' is the link.
(Other definitions for reed that I've seen before include "Grass of marshy land" , "Marsh plant with straight hollow stem" , "Bilk had one" , "It grows in water or marshy land" , "Grassy plant of wet areas" .)
