B.S.
I think its a great idea!
My daughters preschool teacher just has an elf, its not the elf from the "elf on a shelf". I'm not sure what she does for the story, she may have one or she might just tell the class about it. But the kids love it...the first thing they do in the morning is try to find elfy. Its cute! I will have to ask my oldest if she remembers a story being told...my youngest is now in preschool so I'm sure elfy will be coming back out soon!
I wonder if you can find a book at the library?
