The second in the Project Earth-mend Series of environmentally conscious but enjoyable novels for kids who want to learn about how to save the Earth. After their early success with Project Earth-Mend in Canberra in The Greenhouse Effect, Tiger the Cat bids farewell to his owner, Alexander, and heads off to the coast with his friend Wanda the Blue-tongue and the frog Tark (who is really an extraterrestrial from the Planet Griffon) to spread the word about how to save the Earth.
