Cereal topper, perhaps (6)
I believe the answer is:
banana
'cereal topper perhaps' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for banana that I've seen before include "Another of 5 down" , "Long curved fruit" , "Sub-tropical fruit" , "Fruit led by prohibition" , "Fruity type" .)
