The Pied Piper of Manhattan

When New York City suffers an epidemic of pesky ghosts, that even the Extreme Ghostbusters can't seem to defeat, the Mayor calls on a Pied Piper who claims he can rid the city of its demons which he can do so easily. However when the piper asks for far more money than reasonable even for his service the Mayor refuses to comply, the Piper reveals himself to be a ghost, and lures the city's children away and into danger. The Extreme Ghostbusters must stop the ghost and rescue the children.
