A White BiddyBuggy and the return of the Red Monster Tires from Mario Kart 7. (The Red Monster Tires are not as broken as they were in Mario Kart 7) A quick video is provided. To get a better look.
Weird Problems:
For some reason the bottom of the kart will turn blue at times. It only happens with Mario Kart TV though.
This won't work for the different colored Yoshis or Shy-Guys. I don't know why this happens.
