There's a menacing ghost inside Paradise Estate! The ghost turns out to be a shape-shifter named Pluma, who has come to reclaim half of an amulet that is buried underneath Paradise Estate. She's been forced to find the amulet by Squirk, who has kidnapped her grandfather until she can bring the amulet to him. Once Squirk has both halves of the amulet, he will be able to use his powers to flood Ponyland.
