Amphibian gets kicked, by the sound of it (4)
I believe the answer is:
toad
'amphibian' is the definition.
(I know that toad is a type of amphibian)
'kicked by the sound of it' is the wordplay.
'kicked' becomes 'toed' (hit with one's toe).
'by the sound of it' shows a homophone (sound like).
'toed' sounds like 'TOAD'.
'gets' acts as a link.
(Other definitions for toad that I've seen before include "Ancestral hall on River Bank" , "Amphibian with warts" , "Tailless amphibian" , "A loathsome person" , "Wind in Willows hall-owner" .)
