Wow... looking at those intros I realized two things:
You can always immediately tell what kind of stuff you'd find in the accompanying toyline to every show and the cartoons have an exceedingly awesome and catchy soundtrack. I've got a certain fondness for the Gummi Bears theme...
Either way:
If Chris was the main character of an 80s cartoon, he'd also have his own Mattel line of toys with some sort of interconnecting gadgets making it favorable to collect several different figures from the show.
Chris would come with a scrapbook, medallion, blowup-doll (cause unfortunately, weens are a target group, too) and Son-Chu.
Bob would come with Jazz-records, an axe, certificates of patents and the BMW.
Barb would come with... I guess a shitload of random shit that was lying around on the floor of the chinese sweatshop that is forced to make the figures, also the minivan.
