>>32117Wild Kratts is by far the most popular one with kids from my experience, they always want to watch it or the Netflix's Go Dogs Go. Wild Kratts is ok, though doesn't have enough going for me personally, Octonauts does the animal/conservative theme better and I think has more educational value.
Cyberchase is one I have found memories of too! Haven't seen it in years, will have to see if I can track down some episodes, hope it holds up
