A storybook character is an imaginary person in a narrative work of art, such as a novel, play, or movie. Two popular storybook characters are OGRE and Gretel. OGRE is a four-letter word that refers to a large, monstrous, and often cruel creature found in many fairy tales and folklore. Gretel is a six-letter word that refers to the young girl in the Brothers Grimm fairy tale 'Hansel and Gretel, ' who, along with her brother, outwits a wicked witch.
