After Ty the T-Trux loses his home to a volcano explosion, he makes friends with a small Reptool who helps him out. Because of this new friendship, Ty tries to convince the rest of the Dinotrux that teamwork is the best way for them to live.
When a terrible storm causes many of the prehistoric part-truck, part-dinosaur dinotrux to rust and sink into the mud, the smart ones headed south where it was warmer and over millions of years they evolved into the giant trucks we know today.
Illustrations and simple text introduce creatures that are part truck and part dinosaur in a safari through a world ruled by the Craneosaurus, the Garbageadon, and Tyrannosaurus Trux.
