Rufus hatches a plan to save the world by knitting the biggest sock in the universe. However, between Dr. Mu's Scissor Ships, the fact that no one actually knows where the Space Vacuum is and Doctor Muhahaha's hand hovering dangerously over the reset button, saving the world is not going to be an easy task.

Rufus faces a familiar-looking enemy as he tries to prevent Dr. Mu from taking over the multiverse. All he has to do is negotiate three chambers containing his deepest, darkest fears, battle a giant broccoli monster, defeat his evil clone, destroy Dr. Muhahaha's cloning device and prevent him from hitting his time-reversing reset button. Just another day for the hapless TV presenter.

Everyone on Earth has suddenly developed really bad breath and Dr. Mu is, of course, to blame. 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?
