Conway the Contaminationist

A plane crashes down at the Bagge house. A guy inside the plane named Conway claimes by living in a dirty house you can live better, and pay less. The Bagge house gets full of garbage, and Muriel and Eustice get really skinny. The dirty atmosphere ruins their health. Courage turns Conway's plane into a big vacuum and sucks up the dirtyness in their house. Conway leaves, and Muriel and Eustice return to normal health.
