They're back!  Nintendo made this new artwork of Bowser's kids available today as part of the promotional push for the upcoming New Super Mario Bros. Wii.  You may recall that the Japanese gaming magazine Famitsu teased us with a smaller, low resolution image last week.  It's great to see that the Koopalings haven't changed too much since their last appearance despite being given little improvements to help make each kid more distinctive from the others.  Feel free to click here to see it in glorious high resolution suitable for becoming desktop wallpaper.
