Every program had a number of elements woven into the plot line that invited its audience to "Join In!"; in games, songs, puzzles, or stories. The cast also broke the fourth wall, talking to the camera, and thus the audience, as if they were right there on set. The songs broke away from the usual children's format, offering a wide variety of rhythm and styles. The cast also sang live on each show.
Join In! (1989) is currently not available on any services.
