Rufus Hound is transported into a parallel universe and has to stop the evil Dr Muhahahaha from sucking every person on Earth down the back of their sofas. 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 Muhahahaha's hand hovering dangerously over the reset button, saving the world is not going to be an easy task.
