In the days when Bowser was still King Koopa and Captain Lou Albano voiced Mario with the phlegmy chest register of a serial rapist from the Bronx, Mario wasn't the only guy in town with his own show. King Koopa also had a live-action children's show, aired in Spain and California, and it's so obscure that only one episode apparently exists on the VHS tape of a lone fan.

Retrojunk has a great summary of the show, which was a Bozo-like kids' show featuring games, prizes and King Koopa introducing public domain cartoons. By the way, notice that the show's not just called King Koopa's Kartoons... a no-prize to the savvy commenter who can guess why! Florian Eckhardt
