Like everyone around my age who had any sort of access to a house with a Nintendo/NES console in it, I logged plenty of tween-age hours with Mario and Luigi. I wasn't particularly good at any of the Super Mario Brothers games -- I don't think I ever rescued the princess, and it took a borrowed Game Genie to get me past more than the first few levels -- but hoo boy, did I ever have fun.
Therefore, this Super Mario Villains scarf by Craftster user peeloutyourface warms my heart. The scarf is made in intarsia, and probably some duplicate stitch, with fleece fabric blanket-stitched to the back. You'll see familiar "frenemies" like the Koopa Troopa, Goomba, Cloud Dude, and Bullet Bill, and you'll notice that the tension on the motifs is a little bit tight compared to the rest of the scarf, though it looks good overall.
Even better: the designer has posted all the graphs she made to create the characters. That means that you could knit your own scarf, or you could add the motifs to a sweater you're making: try them around the hem, or maybe one over your heart. Or, you could add them to purchased knitwear via duplicate stitch.
The pixelated world is yours, and it probably won't even take you as long to make as it would have taken you to win the darned game.
