The Mysterious Mansion of Jasper/Tropes/Nightmare Fuel


 * The general tone of the series itself.
 * The series' Big Bad, Damien . He is a ginormous being with glowing red eyes, long pointed fingers, an eerie booming voice courtesy of Steve Blum, and a power-hungry desire to consume the souls of everyone.
 * Even the Laughing Ghoul Productions logo that appears after the credits (before the less scarier Walt Disney Television Animation logo) fits the bill. It is basically Disney's answer to the infamous Stretch Films logo from Courage the Cowardly Dog.
