The Bay Landfill is a refuse landfill located near a bay in Lower Manhattan.
In 1997, as revenge, Piper hypnotized many children with his flute and led them to the Bay Landfill. He planned to then force them to march into the bay and drown to their deaths. The Extreme Ghostbusters arrived and manipulated him into releasing his hold on the children. Piper then attempted to use the garbage to bury the Ghostbusters alive but the disharmonious violin playing of Roland Jackson disoriented Piper. Once Piper released his Component Parts Emanations in a last ditch effort, the Ghostbusters trapped him.
