The kids watch a scary old horror movie where a character speaks a certain ancient-language phrase meant to curse the victims to the shadow realm. That phrase? Greb-nefual e-neg! The movie scares some of the kids, but Girl calls it all a bunch of hocus-pocus and speaks the phrase aloud herself. Nothing happens. But one by one, the siblings start disappearing, leaving only a superstitious Boy.

When Cheese accidentally begins writing her new fantasy novel inside Boy's diary, Boy is inspired to live out the life of the novel's great hero! By applying the story to his life, Boy is soon one of the cool kids, making Girl jealous. When she sees Cheese's novel-writing is the cause, Girl helps her write the next chapter to take Boy down a peg or two.
