The figure of Saint Nicholas is typically represented in his bishop's cloak along with a white beard. In some countries Saint Nicholas simply places treats under children's pillows or shoes and is not normally seen in public. In others, however, Saint Nicholas arrives in public squares where he distributes small presents to children. But, whether he appears in person or just leaves small gifts, the lesson in all countries remains the same: behave and you shall be rewarded; misbehave and you shall be warned.

In some countries Saint Nicholas may also appear with other figures. These companions can be either angels or devils that assist Saint Nicholas in various ways. Perhaps one of the most common figures accompanying Saint Nicholas is that of the Krampus, a beast-like creature from the Alpine folklore whose main goal is to warn children who misbehave that if they do not change, he may come to capture them in his sack and carry them away into his lair.

And as for incentives to receive gifts, whenever Saint Nicholas appears in public, children are encouraged to sing a song or say a prayer before small treats are distributed. Countries where one finds the celebration of Saint Nicholas' Eve and Saint Nicholas' Day include France, Malta, Ireland, Italy, Spain, Portugal, Belgium, the Netherlands, Germany, Austria, Switzerland, Croatia, Bosnia and Herzegovina, Czech Republic, Slovakia, Poland, Romania, Hungary, Luxembourg, Slovenia, Greece, Serbia, Bulgaria and even some non-European countries.
