Prickly creature (8)
I believe the answer is:
hedgehog
'prickly creature' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hedgehog that I've seen before include "Spiny mammal" , "Small prickly-backed animal" , "Porcupine" , "one is far from spineless" , "eater of slugs" .)
