In this latest installment of satirical scares, Homer is a wandering spirit who must do one good deed before he can get into Heaven in "G-G-Ghost D-D-Dad", Bart and Lisa see the dark side of "Happily Ever After" in "Scary Tales Can Come True", and the star attraction of a Sea World-style water park stages a war against humanity in "Night of the Dolphin".
