The Zuulusi Demon is a demon who posed as an appliance deliveryman for a company called Zuulusi.
After Janine Melnitz purchased a new refrigerator for the Firehouse, the Zuulusi Demon took on a human form and delivered the refrigerator. After installing it, he had Janine sign for it and left. Once she dispatched Gozer and the Terror Dogs, Janine saw the deliveryman in his true form driving away.
The Zuulusi demon can take on a human form.
