Spiny creature (8)
I believe the answer is:
hedgehog
'spiny creature' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hedgehog that I've seen before include "Prickly mammal" , "one is far from spineless" , "Mrs Tiggy-Winkle, for example" , "Prickly beast" , "Spiny animal" .)
