From the DreamWorksTV website:
Welcome to a world of giant creatures that are half dinosaur, half construction vehicle and all awesome in DREAMWORKS DINOTRUX! Meet Ty Rux, a massive Tyrannosaurus Trux, and his best friend Revvit, a razor-sharp Reptool. Together, the Dinotrux and Reptools join forces for the first time ever to build a bigger, better world and battle back against the biggest and baddest of them all: D-Structs, who threatens to wreck everything they’ve built.
Each DinoTrux episode is only five minutes long. It doesn't take much to bore kids, so these are bite-sized episodes designed for little kids who may get antsy. The show is on Netflix.
The cast includes Ty-Rux (Andrew Francis), a friendly T-Trux (combination Tyrannosaurus Rex and megaton excavator); D-Structs (Paul Dobson), a ruthless T-Trux who doesn't like nosy visitors; Revvit (Richard Ian Cox), a miniature "reptool" who is good at fixing things; Skya (Ashleigh Bell), a combination brachiosaur and crane; Ton-Ton (Matt Hill), an Ankylosaurus dump truck; and Dozer (Brian Drummond), a Triceratops-bulldozer with an attitude who must learn to get along. It is from the book by Chris Gall.
DinoTrux toys, incidentally, should be available at Toys 'R' Us.
