Are you sure? I could have sworn the voice of "Balok" was done by Ted Cassidy (who also played the andriod "Rok" in What Are Little Girks Made Of and of course is famous for playing the butler "Lurch" in The Addams Family TV series.)
The voice of the fake, scary Balok featured in most of the episode was Ted Cassidy, yes, unmistakably. But the voice of the real
childlike Balok seen at the end of the episode was Edmiston (dubbing over Clint Howard).
