For our final monster, I give you the Norse boar monster, Gullinbursti. I was hoping that translated to something cool like "gut bursting pig," but it actually means "gold bristles." An apt name, though, considering this pig glows-in-the-dark. It can also run on water and fly through the air, all at speeds faster than a thoroughbred.
This boar was hand-forged by the dwarven brothers Brokkr and Eitri in response to a dare from Loki. Loki was all "You can't make anything as good as Sif's hair, or Odin's spear, or Freyr's ship...," and Brokkr sassed back "Yes we can, here's a sparkly pig!" Brokkr won.
