McDonald's YumChums (partially found TV commercials 2004)

In 2004, McDonald's UK launched an ad campaign in order to encourage children to eat healthy. A series of ads were produced featuring Ronald McDonald keeping active in order to help a group of animated characters inside of his body known as the Yum Chums. The Yum Chums would sing a different song about keeping active while eating healthy in each ad. According to this forum post, the ads were uploaded to the internet when they were first released, but the official Yum Chums website has since shut down. No clips or screenshots are currently available on the internet.
