The Worst Witch
Miss Hardbroom suggests that Miss Cackle poses as Agatha and invites Agatha's rebellious coven in, whereupon Mildred and the others will turn them all into snails, which happens. As Mildred, Maud, and Enid go back to bed they say they want Miss Hardbroom as form-teacher. She suddenly appears in front of them and is friendly for a brief moment before strictly telling them to get back to bed with no candles on.
