A few more still shots and screencaps from the new show have surfaced on the internet, and... well, if we made a fuss about ARTHUR switching to Flash, the animation for this show looks remarkably cheap and underwhelming, almost like 90s-era CGI: they all look like walking, talking PVC figures, there's no texture to their hair, fur, clothing, or anything.
We do, however, get a better idea of how big they'll be: they're considerably larger than they were in their CGI-movie form, but they're also obviously shorter than they were as cartoons... which pretty much makes sense; design-wise, they're genetic experiments of their cartoon and CGI designs, so I guess that would effect their sizes too.
