Cyberchase. Don’t be put off by the fact that this is an educational animated series: on the one hand, it does not treat viewers as fools, on the other hand, it provides the educational part as creatively and plot-wise as possible.
If you haven’t watched this animated series, but love something light and funny, adventure, with charming heroes and interesting villains, then I'll be happy to introduce it to you. If you have already watched Cyberchase, from this article you will find out what happened to Hacker and everyone before the first episode, as well as such surprising theories as Dr. Marbles sabotaging the repair of Motherboard, how specifics of the computer world cleverly explain some silly cartoon tropes, what would have happened to the kids if they hadn't returned from Cyberspace, and how the virus storyline should have ended.
