Here's five characers I'd love to see in the next Mario Kart:
1. Vivian (Paper Mario: The Thousand Year Door)
2. Lubba (Super Mario Galaxy 2)
3. Ludwig Von Koopa (Super Mario Bros. 3/New Super Mario Bros. Wii)
4. Kamek (Super Mario World 2: Yoshi's Island/New Super Mario Bros. Wii)
5. Count Bleck (Super Paper Mario)
And as a super special secret character... BABY SAMUS!
