Mario Kart Wii 100% Walkthrough Part 25: 150cc Flower Cup (Attempt 2)

After playing with Rosalina and the Flame Runner again, I got an even worse score. This time, I got 12th place in Wario's Gold Mine, because I kept falling off the track. I don't understand why these unfortuante miscalculations keep occuring... But I'm not going to give up... Because I have limited time to do so before my trip to New York.
