Bunny talk? (6)
I believe the answer is:
rabbit
I believe this is a double definition.
'bunny' is the first definition.
(I've seen this before)
'talk?' is the second definition.
(rabbit can informally mean to talk)
(Other definitions for rabbit that I've seen before include "Animal called coney" , "Burrowing animal, lives in warren" , "Gas" , "may be pulled out of Derby, perhaps" , "8's friend with relations" .)
