Polka Dot Door

Polka Dot Door is a long-running Canadian children's television series which was produced by the Ontario Education Communications Authority (later known as TVOntario) from 1971–1993. The series featured two hosts who acknowledged and presented directly to the home viewing audience.

The content of the shows was generally geared towards education and creativity. Each week of episodes focused on a single theme with each weekday assigned a different "motif" in which the theme was explored in different ways (For example, Tuesdays were "Dress-Up Day" in which the hosts would use costumes to explore the theme).

One of the most well-known elements of the series was "Polkaroo": a mythical character whose name combines the words "polka dot" and "kangaroo". The character would generally appear twice a week (on Thursdays - "Imagination Day" and "Treasure Day") to only one of the two hosts while the other made an excuse to leave (in reality this was to don the Polkaroo costume). Upon the second host's return, they would typically express disappointment when informed that they had once-again missed Polkaroo. Despite appearing only once a week, the character became one of the iconic features of the series.
