What is 'Switch Witch'? Utah family swaps daughter's Halloween candy bucket for toy

Families woke up to bags of candy after a night of trick-or-treating for Halloween. One new idea for what parents can do with all those treats, called the "Switch Witch," is sparking debate online.

A Utah family posted a video on Instagram that has been seen millions of times.

After trick-or-treating, their 2-year-old daughter chooses five pieces of candy to keep. Then, she puts the rest of the treats in a bucket and leaves it on the porch overnight.

That's when the "switch witch" takes the candy and leaves a toy in its place.

The dad says the girl is just as excited about the switch witch as she is trick-or-treating.
