Drew amphibian, say (5)
I believe the answer is:
towed
'drew' is the definition.
(towing is a kind of drawing)
'amphibian say' is the wordplay.
'amphibian' becomes 'toad ' (toad is a kind of amphibian).
'say' shows a homophone (sound like).
'toad' sounds like 'TOWED'.
(Other definitions for towed that I've seen before include "Pulled along" , "Hauled" , "Dragged behind" , "Helped when powerless" , "drawn" .)
