Perhaps the Glum-Sow or Glo-Sow is a Christmas beast from Denmark.
It is a peculiar pig, as the name “Glum” refers to an old Danish word for terrible and dreadful.
When called “Glo” Sow, it relates to something glowing.
The Glum-Sow is therefore dreadful and glowing, with shining eyes, large fangs, and bristles on its back as sharp as knives.
If it runs between your legs, you’ll be split!
