The Jurassic Cubs have found their parents but, unfortunately, they have to greet them again so that they can finally find a home for everyone. Thus, the wise Saùro agrees to host the puppies he will be teaching as well as his clumsy and likeable assistant Nichus. The peace rediscovered, however, has a short duration because that “mechanical souvenir” kept in the Cave of Wonders comes to life, risking to bring havoc in the Jurassic. This is the robot T-3000 that, after a quick fight, manages to incorporate within itself a fragment of black meteorite that allows him to travel in space and time with the unic objective of returning in the future from his master Taurus. The Jurassic Cubs will do everything to stop him chasing him everywhere until the decisive battle that will see the same T-3000, in love with the computer Lisa9000, betray the perfidious scientist making it end up in the Jurassic together with the dino-cyborg Roy. Taurus is found to be regressed to the state of troglodyte, T-3000 can be reunited to his beloved, the Jurassic Cubs can re-embrace their parents who have decided to settle in the Red Mountains and, moreover, Roy joins the group after becoming a mechanical dino-cub in all respects.
