Pouched animal from down under (8)
I believe the answer is:
kangaroo
'pouched animal from down under' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for kangaroo that I've seen before include "Marsupial from down-under" , "One's jumpy" , "Illegal court of marsupial origin?" , "Jumping animal" , "Jumper of grey or red" .)
