Still, the way the characters run (especially when Arthur gets up from the lunch table and runs from the cafeteria) reminds me a lot of Martha Speaks. But both are made using Flash (Toon Boom?) animation, so there's the reason I saw the resemblance.
You can definitely see it in the Molly clip, while Binky is reading her letter. His legs have a very robotic look to them while he walks.
The animation of Season 16 in a lot of ways reminds me of Doki66's "Not Stanley" series (on YouTube, but be warned, they have foul language), but it works for that because it's supposed to be badly animated.
And the perfect character to first call them out would be Buster. Dunno why, but I just think that would be really interesting to watch.
In all honesty, I'd throw something at my TV if it were Francine calling Muffy out for hypocrisy, or Muffy calling out Francine. They both need it.
But if there ever is a scene where they both got called out, Francine would somehow Karma Houdini her way out of it. In any episode where they are both put in a bad light, Muffy is portrayed as being just slightly worse, even to the point of being a scapegoat, so Francine can come off looking good (again like in "The Good Sport" episode). That has always been the main thing that bugs me about Francine, that she gets to play hero even in the same episodes where she was a bully.
