Sole survivor of ancient disaster, Littlenow knows the complete history of the world. That's why he is known as a Thesaurus Rex.

He emits a huge primeval roar, involuntarily, when frightened, and just for an instant reverts to his former gigantic size. Once the largest of all animals, he is now a shrunken, glowing green dinosaur currently living in fabulous caves under an old landfill.

Littlenow is the only living creature to have confronted the Baron Waste. Along with his friends, Cubbacius and Athena, he sets out on a journey to help alert the world to the nefarious schemes of the Baron Waste.

Littlenow helps teach children and adults alike the importance of preserving and conserving the Earth's resources and its inhabitants.
