Surgery on Barbie maybe helping? (6)
I believe the answer is:
dollop
'helping?' is the definition.
(I've seen this before)
'surgery on barbie' is the wordplay.
'surgery' becomes 'op' (short for operation).
'on' is a charade indicator (letters next to each other).
'barbie' becomes 'doll' (I've seen this in another clue).
'op' put after 'doll' is 'DOLLOP'.
'maybe' is the link.
(Other definitions for dollop that I've seen before include "Big spoonful" , "Quality of eg cream" , "Small mass of eg cream" , "Lump - of custard, perhaps" , "Blob" .)
