Aqua Kids, which has been on the air since 2000, has been under the radar for most of its 12 year run. The series finally found a home in my district, airing on the CW affiliate, this season.
Here's a sample clip, courtesy of the series' YouTube channel:
I think part of the reason it's been under the radar is that while its intent is to educate children, specifically preschool & elementary school students, it is currently airing on 128 stations, plus the Kids & Teens Network, which isn't readily available. I've seen a few clips, and I would encourage parents to do their part to get their children interested, as this would go a long way toward developing career goals.
