White Rider Achievement
The Root of All Evil: Surf the donut down the river for 20 seconds
During Mission 3: The Root of All Evil, you will come to a point where you are making your way down river. Keep your eye out for a large yellow/orange donut in the water, it’s pretty hard to miss. Once you see it, just jump on top of it and let it move. Stay on top of the donut for 20 seconds to unlock the achievement. Time is counted cumulatively, so if you fall off, just get back on.
