I lived in Vermont for most of my young life, until i was 12 years old. The TV in Florida was much different thant the TV in Vermont. One thing in particular, french programming was a mainstay and translated french progromming was the alternative. Two of my favorite programs growing up were The Racoons and Spartakus and the Sun Beneath the Sea. The Racoons had a huge budget, and every episode looked like a disney movie, new short movies are still being made today. Spartakus stood out for me, as it was Science Fiction Themed, had strange creatures, and just did not make much sense.
So this is this lost-world-city called Arkadia, which is way under the surface of the earth and lit by this artifical sun, which is dying. A team of kids (i guess) defy the law of the world, and go out looking in the Archives (?) which to me looks like some acients computers in storage. The build an andriod and bring her with them, and they goto the surface for help. They meet two kids and lots of assholes. It can be quite comical, but even for a french cartoon is pretty serious. Oh, and theme is sung by Menudo. It was translated and aired in America for like a year on Nickelodeon, but i continued to watch it on the french channels for years to come.
