The Dinotrux are enormous part-dinosaur, part-truck monsters that roam the earth, rumbling and honking and wreaking havoc. But even monsters need friends! And Dozeratops needs the help of his friends to build a bridge that will let the Dinotrux cross a river to meet one another. He calls Velocitractor to drag logs into place, Craneosaurus to lift them, and Cementosaurus to finish everything off. Join in the fun in this Level 1 early reader that introduces newly independent readers to these awesome monsters of mayhem!
