Meet Ty Rux, a massive Tyrannosaurus Trux, his little Reptool buddy Revvit and the Dinotrux crew who join forces against the evil D-Structs.

When Revvit and his Reptool friends venture out of their ravine, the Dinotrux band together to save them from a flock of savage Scrapadactyls.

Ty Rux leads the Dinotrux on a nighttime raid to rescue Ton-Ton, who's been snatched by a pack of Scraptors and taken to their hive in Scraptor Valley.

Just as Ty Rux welcomes Garby, a loud and smelly Stegarbasaurus, to the crater, Revvit disappears and the gang embarks on a dangerous rescue mission.
