Figure's appeal, eating junk (6)
I believe the answer is:
statue
'figure's' is the definition.
(statue is a kind of figure)
'appeal eating junk' is the wordplay.
'appeal' becomes 'sue' (I've seen this before).
'eating' means one lot of letters goes inside another.
'junk' becomes 'tat' (I've seen this before).
'sue' placed around 'tat' is 'STATUE'.
(Other definitions for statue that I've seen before include "Stone figure" , "Firm figure" , "Piece of sculpture" , "Stiff sort of personality" , "Figurine" .)
