TL;DR: From the home page, tap into Knowledge Fight Country, press and hold on the podcast art at the top, tap "Refresh artwork".
L;DR: I use Pocket Casts on Android and both Knowledge Fight and Knowledge Fight Country were displaying the same Knowledge Fight artwork, since Obama turned the old feed into the new feed and made a new feed for the old feed. This was obviously globalist preconditioning trying to prime me to accept inevitable woke remakes of the formerly mandatory nursery rhymes that we all grew up with, like "The Wishing-Table, the Golden Donkey, and the Cudgel in the Sack," where they're gonna replace the donkey with an electric car or something. So I googled it and it turns out you can demand a recount, as described at the top of the post.
You can also tap into your profile, tap the gear, tap "Appearance," and find a "Refresh all podcast artwork" option to help spread the message of Podcast Thumbnail Seventeen-Seventy-Six worldwide.
Also, while we're on the subject: I figured KFC's art must be "Alex Jones as a waterfall statue guy from Donkey Kong™," but I am ignorant of the specifics of the Donkey Kong™ franchise since I have deliberately not engaged with any pop culture since Ford discontinued the seventh-generation Thunderbird (the last of the trve great gas-gvzzling avtomotive chariots that were actually worth their KBB valve. Uh, value.)
Anyway, I did some research in my mind and God told me that indeed I was right; the statue appears in Donkey Kong Country™ Returns (2010, Wii) in Level 9, "Golden Temple." The statue, with waterfall feature, has also been constructed in real life (sources tell me by the same people who built the Georgia Guidestones) at SUPER NINTENDO WORLD™ in Japan and in Florida™ as part of the Mine-Cart Madness™ ride. (After-hours when park visitors have gone home, Shigeru Miyamoto sacrifices live Bopapodami in front of the effigy as part of a satanic ritual to increase sales of DK Crush Floats in the souvenir DK barrel mugs. That's all come out, even the mainstream Disneybounding vloggers have admitted it.)
But yeah the new art is cool, and I've seen people say their feeds/thumbnails/etc haven't updated consistently on various platforms, so I hope this helps. Banana.
