Unholy Cow — John H. Carroll

Opal has never been trick-or-treating because her parents think Halloween is evil and candy is bad for children. She sits alone in her bed with her emo bunny and longs to dress up and ask strangers for candy.

Meanwhile, everyone keeps talking about holy cows, but nobody wants to discuss evil unholy cows that creep through nighttime pastures in search for opportunities to make the world a terrible place to live.

Runyx the Unholy Cow, together with Stryk the Scarecrow and Able the Raven have a mischievous plan to change Opal's life.
