So, we slavs have some habits, holidays and saints, a notable one is st.Micholas, which is celebrated on 5th of December. He brings stuff and is generally a nice guy, but czechs are pros at leaving permanent ...deflect on kids mentality with scaring the shit outta them. So we have a Micholas and a "fairy devil"or mostly known as krampus tagging along. Trust me, grownups might be smiling, but seeing some of the kids going derp after encountering the devil, I am sure those keep on peeing in their beds for months.
So, we've actually added an angel too, but i am pretty sure it doesn't help to recover from the shock. Some of those angels look more horrifing than the devils.
