Okay, there's this...interesting...show I just discovered. I can't seem to find any information about it, except for a few videos of the show itself. I guess it's an advertisement of sorts. Any clue what it's called (besides "Non-Human Specials")?
It's a Chinese cartoon about ancient myths, titled "非人哉" (It means "Not a Human", and I do not know its official English title). I watched it on https://www.youtube.com/playlist?list=PL0Cq3jn9pFuXbMW2toLRGRcSB291wgkjr. However, there is no English subtitle. The video you saw is a collaboration (advertisement) with Pizza Hut.
