Donkey Kong and others (4)
I believe the answer is:
apes
'donkey kong and others' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for apes that I've seen before include "Copies the primates?" , "Imitates like primates" , "Zoo animals" , "Imitates in every aspect" , "Parrots" .)
