Grunhilda is back in all-new adventure. The Lunch Witch has her hands full when one of her familiars accidentally casts a spell that turns everyone nice. Needless to say the ancestors are not pleased. It's more ghoulish fun featuring everyone's favorite career-changing sorceress! Grunhilda the Witch has a weakness... a tiny soft spot on her black and crusty heart. She continues to hide the nice feelings she has when she gets a letter from former Salem Elementary student Madison. But she can't keep up the ruse for long because her familiars are onto her... and so are her ancestors! The familiars search her hovel and find her collection of letters from Madison. Mr. Williams has a solution, but it involves making a meanness potion from the book that IS-NOT-TO-BE-USED-BY-ANYONE-OTHER-THAN WITCHES (ESPECIALLY-NOT-WITCHES'-PETS). But anything that can go wrong does when he accidentally mixes up a positivity potion instead... and it starts to affect everyone in town. Birds are singing. Flowers are growing. The principal cancels school!
