Elf on the Shelf

Okay, so not sure if this is allowed here so delete if not wanted! We have an Elf at our center but he is not centered around Santa or Christmas like the original. He is just a magical elf, named Jack (after Jack Skellington, the kids named him a few yrs ago). If the kids want to believe that he is one of Santa's elves it's fine, we don't correct them. Our Elf doesn't watch for bad behaviors and reports to Santa. He just moved around the school, leaves actives for the kids to do and is just fun. We've also had parents thank us for doing the elf because they don't want to do it at home, but also know their child's friends talk about it.

I'm running low on ideas. There are a few repeats we do every year. It's hard though so if anyone has ideas that would be great.

Does your school do an elf?
