Despite repeated warnings from Grim, Billy can't resist the temptations of The Bad Book. Upon reading it, he is brainwashed and possessed by the fearsome deity Yog-Sothoth, who wishes to enter the world and recreate it in his own image. In order to achieve this, both the book and Grim's scythe are needed. With the gift of Yog-Sothoth's evil powers, Billy easily overpowers Grim and takes the scythe. He sets up shop in the basement of his family home, where after studying the unholy text, he finds the right incantation. Using the scythe, he rips a hole in the fabric of space and time, allowing horrible monsters and magic to wreak havoc and stain the rug.
In the meantime, Grim and Mandy call on Hoss Delgado for help. After some friendly fire, Hoss quickly identifies the goings-on as Yog-Sothoth's work. They find the possessed Billy in the basement with Yog-Sothoth, who is about to breach the gate. When the combined forces of Hoss and Grim fails to vanquish him, Mandy shoves Billy into the portal with the book and the demon back to The Dreamlands along with him. However, not wanting lowly humans among them, the Outer Gods send Billy back home to his friends' scorn and pity.
