Chief Hopper visits the morgue, sensing something is amiss. The officer guarding the door is reading none other than Stephen King's novel <Cujo>, with the author's face dominating the cover. Hopper feigns familiarity, remarking, "I love that book. It's a nasty mutt, right?" The monstrous St. Bernard, Cujo, is the very creature that inspired the Demodogs. Beyond this, <Stranger Things> is brimming with references to films based on Stephen King's works. In this subtle way, the Duffer Brothers managed to give their idol a cameo appearance.
