Shelley Duvall's Bedtime Stories: The Christmas Witch (1994)

Little Gloria is the worst witch-in-training ever to attend Madame Pestilence's Academy of Young Goblins and Witches. All the other students are busy learning their wicked magic spells and practicing flying broom drills, but Gloria can't seem to get it right. She's always getting in trouble for smiling too much and muddling her magic! But when Gloria hears about a wonderful holiday called Christmas from an enchanting storyteller, she is determined to become a Christmas Witch. First, however, she must prove herself worthy by ending the long and bitter feud between the Pepperwills and Valdoons. It won't be easy, but with the help of her newly found Christmas friends and a lot of love and generosity, Gloria is determined to bring peace and the spirit of Christmas to their planet.. even if Madame Pestilence tries to stop her.
