Bambi, for example, turning up in tall grass (4)
I believe the answer is:
reed
'tall grass' is the definition.
(tall grass plant)
'bambi for example turning up' is the wordplay.
'bambi for example' becomes 'deer' (the Disney character Bambi is an example).
'turning up' says the letters should be written backwards.
'deer' written backwards gives 'REED'.
'in' is the link.
(Other definitions for reed that I've seen before include "Slender grass of wet areas" , "Tall grass plant that grows in water" , "Bilk had one" , "Tall perennial grass" , "Plant of marshy land" .)
