This was part of a line of educational VHS tapes from the late 1980s. The tape apparently dates to 1986. the first half features a bird-like character named Numo, who claims to be of the "Mimble" species. He attempts to teach the viewer simple addition. The second half of the tape tries to tell a story involving two child characters, Timmy and Tina.
The company, Tele-Story, also produced sets of educational audio cassette tapes and books during the early 1980s.
