“Am I a good witch or a bad witch?”
The Witch is a misunderstood person. She just wants to be good, but with all the magic power she has, there are times when she just can’t help being a little bit bad.
For every bad thing the Witch does, she tries to do something good...but it doesn’t always go exactly like she plans. For example, turning the vegetables growing in her neighbor’s garden into candy sounded like a good idea at the time. All of the children in town were happy about it, but her neighbor seemed really mad for some reason!
