This time around, Witchville's denizens are exhibiting their wares at a fair--but, alas, the competition turns into a good-guys/bad-guys contest between Dorrie's mother, Big Witch, and evil Old Irontoes, with ever-alert Dorrie tipping the scales. Suspicious that Old Irontoes is out to steal her mother's entry, a potion to ward off spells, Dorrie steers her toward a bottle of water from the pigs' bucket; and, in a spill playing tug-of-war, gets her mother's potion on herself. So when Old Irontoes' magic mirror turns the other witches into pigs, Dorrie is unaffected--and Old Irontoes, who's mistakenly anointed herself with pig water, isn't: she turns into a pig too. The problem then is to discover which pig is who, to communicate with Big Witch pig, and to find out from her how to turn the pigs back into witches. (That done, Big Witch takes care of Old Irontoes herself.) It's a far cry from the natural witchery of the best of these stories--one, in fact, for only the most devoted of Dorrie's fans.
