The Hudson River is a river in New York.
After the supposed last Shandor died on Shandor Island, Ghost World reclaimed it. During Thanksgiving 1991, the Ghostbusters traced a Mandala node to the Hudson River. They searched through fog aboard Marine Ecto-8 but Peter Venkman was skeptical of its existence, only to see it emerge from below the river. When the Imprisoned Juvenile Sloar was defeated by the Ghostbusters, the island sank again.
