Toad feature (4)
I believe the answer is:
wart
'toad feature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wart that I've seen before include "Small rounded protuberance on the skin" , "Abnormal blemish on the skin, caused by a virus" , "Verruca" , "Surgeon might remove it" , "Small hard growth on skin caused by virus" .)
