Dyb's Demon Audience are demons of various shapes and sizes who gathered in Dyb's Plane to watch the Ghostbusters participate in "Race the Devil."
Much like a game show on the physical plane, the game show ran by Dyb Devlin was no different. It had a live audience, however, they were all demonic entities. Luckily, there were amused by the show and its turn of events. When Ray confessed to eating half of a cookie that had Slimer's slime on it, the audience was clearly disgusted. Once the Ghostbusters caused a cave-in, all of the demon audience fled the scene.
