Hounded S01E03 - Eggy Breath

Rufus is transported to a junk asteroid made entirely from rubbish, the Planet Flotsam, where Dr. Mu is extracting the powerful Grot Particle and beaming it across the universe to Earth. Can Rufus stop Dr. Mu before the epidemic of eggy breath reaches toxic levels and the whole planet has to be evacuated?
