A few days ago, I received a package that contained USB sticks shaped like sushi. Yeah, that’s them up there. But why?

The sticks came as a promotion for the upcoming SouthPeak title, Sushi Go Round, which hits Nintendo DS and Wii in March. Part of what SouthPeak calls the “eat ‘em up” genre (clever!), Sushi Go Round has you in charge of your own sushi restaurant with a series of mini-games that has you keeping your customers happy as you prepare sushi for them. If you play the game using the DSi, you can even use the camera to take photos of anything (your cat, your foot, a sushi USB stick) to make it one of your restaurants patrons.

Hit the jump for trailers for both versions of Sushi Go Round.
