how does elf on a shelf arrive

The Elf on the Shelf is an iconic Christmas tradition, where a small elf doll is placed in a family's home to watch over the children and report back to Santa Claus. The elf arrives on the first day of December, and stays until Christmas Eve, when he flies back to the North Pole to tell Santa if the children have been good or not. The elf's arrival is often marked by a magical appearance, such as appearing in a hidden spot, or being discovered by the children in the house.
