Dogstar

Animation. Dogstar is a spaceship that contains all of earth's dogs, lost during the move from Old Earth to New Earth. The Clark kids miss their dog Hobart and, on board the Valiant, they go in pursuit of the Dogstar. The kids find the Dogstar but it's been destroyed by meteors, or so it seems. On their return, everyone except Simone gets a cold. So it's Simone who is the only one left to pilot the Valiant when it is chased by the BobCat.
