1) Some hippies find their friend Squiddy struggling to breathe with plastic rings stuck around his neck and rescue him.
2) They ask their friend Shaleah if she knows what the plastic rings are from and she says they are from plastic water bottles.
3) The hippies want to help clean up the polluted Chesapeake Bay water so they make new signs with positive messages instead of Shaleah's no swimming signs to encourage helping the environment.
