The Cosby Kids, led by the aptly-named Fat Albert, go through the same kind of adventures they did in the original program. The main difference, however, is that now each episode begins with the kids watching their favorite TV show, "The Brown Hornet". In each episode of this show, the characters learn some lesson about life. After the show is over, the Cosby Kids inevitably face some similar situation, and must put into practice the lessons learned from their TV heroes.
