Smoggies

The Smoggies, the namesake of the television show, are a trio of humans living on a giant boat next to Coral Island. They include:
 * Emma
 * Clarence
 * Polluto
 * Possibly Ralph Robin, Polluto's pet yellow bird (not actually a Robin)

The Smoggies are generally the antagonists of the series, and are constantly polluting the environment and opposing the environmentally friendly actions of the Suntots.
