Hanna Barbara's ark

HB did a religious series where kids time travel to different religious events. If you ever saw the Dungeons & Dragons cartoons, it's very similar in theme and style. The one I watched was Noah's Ark, which wasn't too bad, bringing across the point of harassment and evil of the people around. The "leap of faith" isn't in the miracle of the ship being built, nor in the gathering of pairs of animals, but in the English-speaking kids communicating with Noah and family and being ingratiated into the move with the ark. Here these 70s/80s kids with era-appropriate clothing launched into near pre-history. That's a leap! It's a cartoon, it's forgiven.

The creators didn't labor too many points and at 23 mintues, it was about the perfect length.
