The Cheeseinator produces high-quality Swiss cheese (not from the Switzerland you know). Joe invented it. It is really just a container filled with the Swiss cheese from Bobmart, which is pulled up onto a slope from which it then falls into an Acid Pit. Joe doesn't know that it is falling into an Acid Pit and therefore is still waiting for the cheese to come out. He originally built it to dispose of the mice problem in his house by bribing them with cheese. For now, the mice problem will have to continue.
