DuckTales/Nightmare Fuel


 * The siren from "Home Sweet Homer", no doubt about it.
 * This one needs explanation. Three blond, female duck heads sharing a purple, limb-less, flabby body? Check. Said heads CREEPILY singing in unison? Check. Glowing Eyes of Doom? Check! Said flabby body revealing a demented, hideous, deformed, monstrous, enormous face? Oh hell yes, fucking check!
 * The entire episode, "Nothing to Fear," could count as this, which features everyone's worst fears coming to life and attacking them. For young minds watching this episode in the dark, it is one of the scariest things you can possibly ever watch. Just wait until you see the vacuum cleaner.
