|~ Grim about the Supernatural Storybook of the Underworld.|
The Supernatural Storybook of the Underworld (also entitled "Fairy Tales of the Supernatural Underworld" on the front cover) is a mystical storybook with awesome occultic magic in the possession of Grim and an object featured in the eponymous episode "Nursery Crimes" of The Grime Adventures of Billy & Mandy.
One night, Billy, who become highly awake and hyperactive, calls the tired Mandy to tell her that he has just eaten 19 Atomic Frenzy Cakes. The obnoxious boy exclaims to Mandy that he cannot sleep until being read a bedtime story, so Mandy and Grim, both angrily awoke from their slumber due to Billy's stupidity, have to come over to his house and tell him a story in order to get him to shut up and go back to bed. After the children finished telling each other bed time stories (the first was Mandy's version of the Humpty Dumpty nursery rhyme and the second was Billy's made-up fable about the large but grumpy magic wizard dubbed "Chuck"), Grim decided that he has a story to tell too, and that is when he conjures the Supernatural Storybook of the Underworld, a magic tome consisting of many of the world's classic fairytales.
Grim began telling the first story was the one about a boy called Hansel (Billy) and a girl called Gretel (Mandy). The two young kids get transported into the magical yet a bit creepy universe inside the book and are warned to stick with the story, until Billy wanders off and meets Pinocchio, the titular wooden puppet who wants to become a real boy and the only way to do that, is to cook a real boy and devour his flesh. Billy tries to run, but the puppet locked him in a cooking pot as he began to cook. Meanwhile, Mandy is wandering around, asking different traditional characters (e.g. the not-so-bright Witch of Snow White, the idiotic Big Bad Wolf of Red Riding Hood, the obsese yet not always evil Witch/Old Woman of Hansel and Gretel, etc.) until she finds Billy getting roasted and attacks Pinocchio. They leave Pinocchio (who is now a chair) at the Witch/Old Woman's house, who immediately sits on the chair, but breaks it due her weight.
Mandy is ready to go home now and Billy is finally asleep. Mandy calls for Grim, who is shocked to hear snoring for her response as Grim had fallen asleep, leaving both children trapped inside the Supernatural Storybook of the Underworld, and Mandy's darkly echoing voice swore that they will all pay.
