Warty creature (4)
I believe the answer is:
toad
'warty creature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for toad that I've seen before include "Loathsome creature" , "Hateful person; animal" , "Dangerous driver" , "not found in Ireland" , "Stout-bodied amphibian" .)
