Pukis (Latvian)
Pukis" means "dragon" in English anf though having this name, the Latvian pukis is not evil like it's brothers from the Christian mythology. The Latvian pukis is a bringer of treasure, wealth and happiness, if you have one in your house.
According to our myths, it is somewhat easy to get one pukis for yourself. It is said, you could buy it in Riga or Jelgava's market. When you buy it, the pukis is usually tied up in a rope or wool. The pukis is usually said to bring the treasure at night. Its appearance is as a bolt or splash of bright lightning, sometimes reminding a ribbon.
