Very engaging story of how an orphan gypsy boy and his dog built Thesaurus – the biggest dinosaur in the world What a charming play on words that transcends language barriers and cultures! The friendship saga about Was (pronounced Vas), the orphan boy, and Das, the German Shepherd, is skillfully weaved, drawing attention to cornerstone values for character building. And the environmental imperative theme runs through. Captivating and permeated with fun!
