Tomy Mario Kart RC cars use power-ups, blow our minds

[StANTo]

Well, science, you've really done it this time. We've had to tighten our belts to notches unknown in light of these tough economic times, but we won't be able to resist importing Tomy's Japanese line of Mario Kart remote-controlled cars. Now, this isn't exactly a brand new idea, but Tomy's toys don't just drive around -- they also use power-ups and shoot virtual shells and bananas at one another.

So who's making up the track then? I wonder if you have to buy them individually?
