Comparatively small part? Go overboard! (4,2,3,5)
I believe the answer is:
drop in the ocean
'comparatively small' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'part? go overboard' is the wordplay.
I cannot really understand how this works, but
'part?' could be 'pin' (pin is a kind of part) and 'pin' is located in the answer.
This explanation may well be incorrect...
