Toy sunk into prune creating blob (6)
I believe the answer is:
dollop
'blob' is the definition.
(I've seen this before)
'toy sunk into prune' is the wordplay.
I cannot really understand how this works, but
'toy' could be 'doll' (doll is a kind of toy) and 'doll' is found in the answer.
The remaining letters 'op' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'creating' is the link.
Can you help me to learn more?
(Other definitions for dollop that I've seen before include "Large shapeless lump" , "Inelegant helping (of)" , "Shapeless mass or lump" , "serving food, perhaps" , "A shapeless lump of something soft, like dough" .)
