Spooky spirit (3)
I believe the answer is:
rum
I believe this clue is a double definition.
'spooky' is the first definition.
(rum can mean peculiar)
'spirit' is the second definition.
(alcoholic spirit)
(Other definitions for rum that I've seen before include "Pirate's grog" , "Odd sort of spirit used in grog" , "Sugar-cane product" , "Strange; spirit" , "An odd kind of drink made from molasses" .)
