In his Grandpa Al's garage workshop, child genius Frank Einstein tries to invent a robot that can learn on its own, and after an accident brings wisecracking Klink and overly expressive Klank to life, they set about helping Frank perfect his Antimatter Motor until his archnemesis, T. Edison, steals the robots for his doomsday plan.

"Frank Einstein (kid-genius, scientist, and inventor) and his best friend, Watson, along with Klink (a self-assembled artificial-intelligence entity) and Klank (a mostly self-assembled and artificial almost intelligence entity), once again find themselves in competition with T. Edison, their classmate and archrival, this time studying the science and mysteries of the universe!"--

So far the AstroNuts have failed to find a suitable planet, but NNASA has come up with a new plan: send the the four animal astronauts back through time on Earth where they are to contact early Homo sapiens and somehow set them on a path to a sustainablefuture--trouble is, humans seem inferior to many of the other species (especially the wolves), so the AstroNuts come up with a Survival of the Fittest Olympics, hoping that with a little help the humans...

On their second mission to find another habitable planet, the four mutant animals, LaserShark, AstroWolf, SmartHawk, and StinkBug, splash land on the Water Planet, run by some suspiciously friendly clams, who are very eager to swap planets--and if the AstroNuts can stop arguing among themselves they may find out why before it is too late.
