Comic dog turn in a confused plot (5)
I believe the answer is:
pluto
'comic dog' is the definition.
'pluto' can be an answer for 'dog' (I have seen 'animated dog' mean 'pluto' so perhaps 'dog' could also mean 'pluto'). I'm not sure about the 'comic' bit.
'turn in a confused plot' is the wordplay.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'in' indicates putting letters inside.
'a confused' indicates an anagram.
'plot' anagrammed gives 'plto'.
'u' put within 'plto' is 'PLUTO'.
Can you help me to learn more?
(Other definitions for pluto that I've seen before include "Dog star" , "Disney character - Underworld god - planet" , "Roman god" , "Most remote planet" , "Dis" .)
