pier. There is a small ramp before the mud, use a mushroom toget enough speed to jump over the water and land on the other
at the other side of the water. This can be done without a mushroom, but you have to do 150cc for it and you have to be either really good or extremly luky. Try to hit the ramp befor
you drive over the mud so you don't loose any speed, it's hard to
do it this way, so just use a mushroom.
