The Dogstar goes through a microwave radiation anomaly and ends up the size of a tennis ball. It arrives at New Earth where, by a stunning coincidence, it ends up inside the very Robog that belongs to Mark and Greta Clark. As Zeke says, 'Stranger things have happened,' though he can't think what. Meanwhile, a damaged Valiant crash-lands on Old Earth and the kids meet up with Ramon Ridley who is still trying to clean up the planet. This is difficult because Bob Santino has been dumping all his toxic waste on Old Earth.
