In each short, a series of 30 dots appear on-screen, often with various complications impeding the process. The series was meant to teach children "pre-reading skills by training the eye to take in information from left to right, or as one reads on a page."
The shorts were used as transitions between segments and continued to be shown irregularly on the show through the early 1990s. In many of its later airings, the colors were altered or changed depending on the episode.
The score for the segments was written by Joe Raposo and was among the first pieces of music recorded by the house band for the series in June 1969.
The series was referenced orally in Episode 4199, where Raposo's theme for the segments was used in the score as Abby Cadabby's freckles magically come off her face.
