You better watch out, you better not cry, you better not pout, I'm telling you why.
Santa Claus is coming to town.
At least that is what the residents of Blagoevgrad, in south-western Bulgaria, must have thought when they looked up on Monday to see "Santa" in his sleigh pulled by "reindeer", racing across the skies.
As it turned out, it was as a pilot, dressed as Santa Claus riding a paramotorised sleigh.
There was no red-nosed Rudolph at the front of the sleigh to pull it along, but close enough - there was an effigy of a reindeer .
The flying Santa, whose identity is unclear, first appeared in the skies at the foot of the nearby Rila mountain last year.
His appearance again this year was less unexpected, with children in the area all ready and eager to meet the grey-bearded man in the unmistakable red suit.
