I'm pretty sure the show had a pretty short life. Chances are, you watched the same handful of eps so many times it just feels like there were more. Those Saturday morning slots were notorious for reruns.

I'm not so sure about this... It could be a bit intense for younger viewers. My little one gets scared when the episodes get too realistic. Maybe if they keep it lighthearted and educational without making the mine too creepy, it'd be okay.
