Henchman in a Half-Shell

 Koen (whose video-game style you may recognize) has just put out a fantastic model of Koopa Troopa from the Mario games. In the brief amount of time I spent playing Nintendo games as a kid (mostly Mario Kart), I remember enjoying this character more for his name than anything else, because it was so fun to say. Koopa Troopa!
