Long Island is an island located in the southeast part of New York, just east of Manhattan, consisting of four counties.
Wat lured the Ghostbusters to a fake house at 1313 13th Street in the Levittown suburbs of Long Island while it attempted to gather an army by opening the Containment Unit. The Ghostbusters were hired by Horace Stewart, unaware he was a ghost, to deal with a ghost haunting his mansion in Glen Cove on the north shore of Long Island.
In 1997, Kylie Griffin and Eduardo Rivera kept tabs on the Radioactive Ghost and followed it in Ecto-1 from a safe distance. It led them to the South Shore Nuclear Power Plant. The other Ghostbusters and later, Egon Spengler, met up with them. Leonard Bates purchased a home on Long Island from Adelaide Realty and discovered a wishing well on the property. He mistakenly made a wish for a bride and was stalked by a Ghost Bride on behalf of a Wishgiver. Bates fled his home and got help from the Ghostbusters. After the Ghost Bride was trapped, Bates returned home only to be chased by another. The Ghostbusters arrived, saved Bates, and defeated the Wishgiver.
