This is a reference to the performance of Youkoso Japari Park e at Music Station Ultra Fes 2017; there's some other fan art out there based on how much Yamashita Mami was getting into it: http://kemono-friendsch.com/archives/37586
Unfortunately, I haven't been able to find a video of it that's still available.
I think I saw that video on a Fan Page on Facebook, I can't remember which one, though. Anyway, I remember seeing her and enjoying how much fun she was having in her character. She's 100% Margay, lol.
I hope things get straightened out at KadoK and that we get to see her in Season 2.
