Pulping vegetable on your head (7)
I believe the answer is:
squashy
'your head' is the definition.
I can't judge whether this definition defines the answer.
'pulping vegetable on' is the wordplay.
'pulping' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
'vegetable' becomes 'squash' (squash is a kind of vegetable).
'on' is a charade indicator (letters next to each other).
'y' put after 'squash' is 'SQUASHY'.
Can you help me to learn more?
(Other definitions for squashy that I've seen before include "Like overripe fruit" , "Yielding" .)
