Elf on the Shelf is Santa's finest helper and a favorite Christmas tradition. When Christmas rolls around, this cute elf comes alive. Instead of placing the elf—literally —on a shelf all December, get creative and try different elf arrangements. Get Santa's scout his own kissing booth, or convince the kids to open their advent calendars on time (because everyone knows how much elves love chocolate!).
