S02E15 Keeping Cappie Happy

Hattie’s younger sister, Cappie the Witch, makes her first live appearance, having been previously seen in a photo that Hattie shared in "The Explorer's Club." When Cappie's magical powers begin to surface, she inadvertently puts Hattie into a deep slumber, leaving Wally in charge of watching over her.
