Slimer was a legendary ghost to all on the original staff of the Sedgewick Hotel. His usual territory was the twelfth floor, but his outings were usually non-violent and simply involved eating food. As a result, the hotel was able to keep a lid on the supernatural problems (for a while). For some reason, Gozer's approaching time of arrival provoked Slimer (and many other ghosts) into being much more active than usual. Eventually the staff couldn't keep the ghost a secret anymore and called the Ghostbusters. However, the Ghostbusters had not yet fully tested their equipment and weren't completely prepared for a full capture. Ray was the first to find Slimer, but missed him and Slimer escaped into the next hall, where he slimed Peter Venkman.
After many errant shots and the resulting destruction, Slimer flew into the Alhambra Ballroom where the Ghostbusters made another attempt at capture. Though Slimer is at first tossed around by some more missed shots, the Ghostbusters eventually manage to get him in the streams. Slimer was then caught in the Ghost Trap and put in the storage facility. However, he was released with the many other ghosts when the storage facility was shut down by Walter Peck. Slimer occupied a hot dog cart on 1221 Avenue of the Americas in front of the Rockefeller Plaza. When the Hot Dog Vendor opened the cart, he was naturally shocked to see a ghost. After the Ghostbusters defeated Gozer and left Central Park West, Slimer was sighted in the area.
