Some have even found their elf trapped inside the television! (Type Elf trapped in the TV on YouTube to manage this hilarious effect).
The perfect addition to an advent calendar, the elf helps children behave on the countdown to Christmas and makes the festive season come to life.
Appearing on December 1, the Elf on the Shelf book tells of how he will be reporting back to Santa each night on the run-up to Christmas Day.
You can introduce the elf with a letter written to your children, telling them the rules for having the elf in their home and asking them to pick his or her name.
