The Smoggies

Here we have another of the environmentally friendly cartoons that were prevalent in the early 90's. This time we have The Smoggies!

The show took place on or around the fictional Coral Island, and revolved around a group of island-dwelling people called Suntots and a trio of polluting treasure hunters called the Smoggies. The Suntots spent much of their time defending their island paradise from the Smoggies, who polluted everything around them and lived on a coal fired steam ship, the SS Stinky Poo, which polluted the water and air around the island. The Smoggies constantly tried to destroy the Suntots' home for their own benefit.
Almost every episode had the environmentalist Suntots outsmarting the Smoggies latest scheme, after which the Smoggies invariably hatched another scheme. Thus, the show also explains the importance of protecting the environment.
A recurring theme was their attempt to steal the island's "magic coral" (which the Smoggies believed granted eternal youth), or find some alternative way to maintain youth. The show often implied that the magic coral did not actually exist, however, and were just manifestations of the Smoggies' (mainly Emma's) greed and vanity.
