Come on! How hard can it be to find a replacement for the moon? Just head into space with a Moon Detector and it should be easy, surely? Well, maybe not for our heroes. They are after all dogs and prone to, well, shall we say, ‘little’ accidents. For example, knocking the spaceship off course; heading directly into the sun, being attacked by aliens… being scared to death of traveling in space… And there’s more! Down on planet Earth things are going well either. Speed Bump Charlie, the wicked cat, has hatched a plot so extreme and so heinous it cannot be recorded here. If you have read the other books in this series you’ll know that he does not like dogs. They spoil his freedom by chasing him up trees; they get far too much attention from their owners and worse; they leave slobber in his food bowl. This time Speed Bump Charlie and his side kick, Furball, think they have the best device in the world that will rid the world of dogs forever! Can Astro and the gang really find a replacement for the Moon? Can Speed Bump Charlie use his ingenious device to lure every dog in the world to their doom? And can, Alfie really ‘blow’ the spaceship back on course?
