Nine-year-old Flo is a talented cook, and as the Food and Fun looms on the Dog Bone Asteroid, she sets out to secure the ingredients for the perfect pudding, in exchange for some of her parent's inventions. Helped by the creative talents of her seven-year-old brother, Hugo, Flo hopes to create a spectacular pudding that the family can trade for whatever they need to continue with their space travels. Flying in the family space pod, armed with unique inventions such as the sucking and sorting hoover and the zapa-snapa, Flo visits Mercury, Venus, Earth, Mars, Saturn and Jupiter, in search of original and delectable delights, such as hot ice cream and volcano-smoked pancakes, for her perfect pudding. Full of colourful planetary facts, wacky inventions, near disaster and a lot of laughter, Flo and Hugo's ingenuity is tested to the very last minute.
