Evidentally, Japanese science folk at nanobiological laboratories of the University of Osaka got bored whilst solving real problems and decided to do something significantly more light-hearted to cheer us all up. Here we present Fungus Mario in all his fluorescent glory!
Those Osaka University boffins achieved this stunning effect by engineering bacteria to "express fluorescent proteins and carotenoid pigments", whatever that means. The irony of Mario getting the fungal treatment after spending two decades doing his utmost to eradicate them hopefully isn't lost on those crazy nanobiologists.
If you're a fan of Mario and his fungal foes, don't forget you can vote for New Super Mario Bros. Wii in our Nintendo Life Game of the Year Awards. Need reminding how good it is? You'll want to read our For Your Consideration article, then!
