A Book of Pagan Rituals is a large hardcover book about paganism.


Jenny Moran started research on an entity the Ghostbusters encountered in the City Water Tunnel No. 3. Going on the fact it had a head shaped like a pumpkin and an Irish accent, Jenny focused on a ghost that manifested during the festival of Samhain. Once Ray Stantz came out of the shower, she presented a page to him that had an old drawing that resembled the ghost.
