The theme for the "Polka Dot Door," a five-day-a-week children's series, explained the main concept of the show "songs, stories and so much more!" Two human hosts a man and a woman led simple games, stories and songs inside a giant playhouse that had (egad!) a polka-dotted front door. Each show had a specific theme, with the stuffed toy inhabitants (including a doll and a teddy bear) made part of the action. During each show, the Polkaroo a mischievous polka-dotted kangaroo visited the two human hosts, while other guests dropped by on occassion. This series, which originated in Canada, was also broadcast on PBS stations in the United States.
