Frank, the frog, noticed that his pond and the stream which feeds it, has got garbage and an oil slick floating on it.  He turns into ‘Superfrog’ and jets off to find the source of the pollution.  His presence is noticed by masses and masses of children, who follow him.  He goes to the head guy of the factory giving off the most black smoke and tells him to ‘stop spoiling our pond,’ and threatens him with some of his own pollution. The intent to stop pollution is a commendable one, but it falls short when Superfrog propels himself with his own natural gas and threatens the head guy with an expulsion of gas.  The meaningful lesson turns into a gag and detracts from the cause.
