Beast babbles ode (3)
I believe the answer is:
doe
'beast' is the definition.
(doe is a kind of beast)
'babbles ode' is the wordplay.
'babbles' indicates anagramming the letters.
'ode' anagrammed gives 'DOE'.
(Other definitions for doe that I've seen before include "Mummy rabbit" , "Rabbit, perhaps" , "Female kangaroo" , "possible mate for Rudolph?" , "Animal" .)
