Nightmare Balloon Boy talks in complete sentences. As with the other nightmares, he has no qualms about torturing his victims with his bony, metal hands. He also has a tendency to mock his victims whenever the opportunity presents itself. Nightmare Balloon Boy's appearance is similar to the original BB, except with a more menacing design. This includes large, pointed teeth inside of his large mouth, dark-blue eyelids and teeth gums, and long claw-like fingers.
