On the character selection screen of Mario Kart Wii, looking closely at Donkey Kong's innermost toes shows a red texture resembling painted nails (left: normal view, middle: zoomed in). This is actually a mapping error that applies Donkey Kong's mouth texture to his feet (right). pic.twitter.com/3aq3jVUyP3— Supper Mario Broth (@MarioBrothBlog) February 1, 2020
The weirder the bit of trivia, the more it intrigues me. That's why today's finding has me absolutely giddy. It doesn't get much weirder than this.
In Mario Kart Wii, it appears Nintendo made a mistake that lead to a texture issue. When selecting Donkey Kong on the character select screen, you can see a slight issue with Donkey Kong's feet. Turns out a texture issue has lead to Donkey Kong's mouth texture being applied to his feet. It's one of those things you probably never noticed in-game, but now can't unsee it!
