It takes some serious dedication to video gaming to take the time and effort to make a guitar in the shape of a secondary character from the Mario series but that’s just what some guy has done with this great looking Koopa Troopa guitar. So maybe there are more obscure enemies in the Nintendo universe but would the average Joe on the street recognize Koopa? Probably not. Most people would probably compliment you on the sweet Teenage Mutant Ninja Turtle guitar if they saw this. Secondary character or not, this is a really nice looking guitar and I’d love to hear how it sounds (playing the Mario Bros. theme song, natch).
