Nightmare Fuel / Dr. Chaos

• Especially one of the mini-bosses that looks like a hybrid of Frankenstein's Monster and Uboa.
• The opening title screen. You can't see it in the photograph provided on this page, but if you wait a few seconds at that title screen, you get to see someone being chased around the house by something you can only vaguely make out.
• Dr. Chaos is no slouch when it comes to jump scares, either; it's quite startling to have a freakish monstrosity pop out at you during a 1st-person segment and then chase you out into the halls.
