Have your Elf leave the kids a note asking them to plant his magic seeds (Tic Tacs) into a bowl of sugar for a sweet surprise. When they wake up the next morning the seeds will have grown into cookies!
Our Elf on the Shelf arrived with a note from Santa and an empty box for each child. They were instructed to fill their box with toys to donate to other children, so Santa would have room to leave new toys. Great Idea!!
