The Balloon People is the ninth episode of the first season of the Superfriends. The episode introduced a family of aliens called Balunians, who had a strange balloon-like physiology. This was the third episode of the show to deal with the subject of pollution, with the last two times that was addressed being in Dr. Pelagian's War and Too Hot to Handle. Once again an alien world is portrayed as being too polluted to live on. This planet is called Balunia, and within the context of the story the Balunians leave their homeworld, and one family of Balunians land in Marvin White's backyard.
