Why is blitzen always wet?

Blitzen is always wet because it is a term used to describe a character in the popular holiday lore associated with Santa Claus's reindeer. The name "Blitzen" is derived from the German Word for "lightning," and in some stories, it’s suggested that he has a connection to storms and rain. Additionally, in certain adaptations, the reindeer are often depicted flying through inclement weather, leading to their perpetually wet appearance. Thus, it's more about the imagery and characteristics attributed to Blitzen rather than a specific canonical reason.
