Animated World of DC Comics: The Super Friends meet the Balloon People (1973)
One of the better, more entertaining episodes of the 1973 Super Friends series saw the debut of a family of "Balloon People". Crim and his family have landed on Earth, and eventually become house guests of Marvin (Frank Welker). The Balloonians draw the attention of Noah Tall (Norman Alden in a dual role), and his marblemouthed sidekick, Twisty (Casey Kasem). Let's just see what happens:
Unfortunately, when the series was revived four years later, no thought was given to revisiting the Balloonians or anyone else the Justice Leaguers encountered during the first season. Would've been a lot more fun.
