The Snow White level. You have a limited amount of time, and you have to go through a book full of recipes and spells and sorting through ingredients in a dimly lit dungeon while Snow White is fading away, and every time it takes you too long, Queen Grimhilde will go down in the dungeon and put one of the dwarfs "to sleep". It's a pretty stressful experience for a little kid.
When you defeat each villain, there's a wacky little animated sequence of their defeat. Except for the Queen Grimhilde. After she gets hit with her magical ammunition, she transforms into an old hag. She then looks at her reflection in the Magic Mirror, which shatters because of her appearance, so she screams at the top of her lungs with bulging eyes.
