It seems Nickelodeon had some spooky foreign serials laying around, so why not put them together and make yourself a show? There's the Haunting of Cassie Palmer, about a girl who summons a ghost; Under the Mountain, where two psychic children face off against alien invaders; Children of the Stones, where a small English village is not what it seems; Into the Labyrinth, where two sorcerers battle across space and time; and The Witches and the Grinnygog, a mystery involving magic, gargoyles and spirits.
