You can learn more about the story and the elf's purpose here.
Our elf, Pinky Frost, is a trip. She's always getting into something and, as part of our tradition, she shows her face every year the day after Thanksgiving. It's pretty crazy and her mischief gets on my nerves but Munchface loves her and it's a fun advent calendar of activities for the family. I almost forgot that she would be back to get on my nerves until Munch mentioned it the other day. If you are considering purchasing one, be warned (... or inspired): THEY GET INTO TROUBLE!
