I know this word "Spunk" has a different meaning in English... But in Danish it's the name for a much loved licorice and wine gum candy.
In 1971 Galle & Jessen were looking for a name for their new candy. They came across the name "Spunk" in the Pippi Longstocking book "Pippi in the South Seas" where the main character Pippi invents a word for which she can find no use. The books about Pippi and her adventures were written by Swedish author Astrid Lindgren, and they are some of the (if not the) most popular children's books in Denmark (probably in all of Scandinavia).
The candy boxes bear the name Spunk and a drawing of a "fantasy animal" made by an 8 year old girl. As with the Danish Ga-Jol pastilles (also produced by Galle & Jessen), the boxes have a little saying or word of advice on the inside of the box lid.
Spunk comes in three versions:
Pastilles made from salty liquorice and sold in a black box.
Fruit flavoured wine gums (like the box on the photo above) and last but not least
the brown cola-flavoured wine gums sold in a brown box.
