Continuity mistake: In the story titled "Quebec Province 1975", child witch Lucy gets back at her bullying cousin Angela by shrinking her to the size of a mouse. Minutes later, Angela looks up, lifts her hands over her head and begs for mercy. Obviously Lucy is preparing to step on her. But we see Lucy lifting her foot off the floor several seconds after Angela starts begging.
