On seaside run in technical time trials, head to the two rocks with palm trees on top. Go through them and turn right, keep going straight until the mountain has sort of a dent in it. Turn around and there is a rip in the mountain, you can drive right through it.

Go to the career mode and win 15000 points to get Andy's jet-skis then use his orange one to do a pro world career you should be able to win at least 50000 points if you try. I have gotten all of them by doing this.

In cannonball cove when you go into the cave with th skull in front of it about half way to the large room (on the left side) you will see a crack (that is near the bottom) that is in the shape of a circle run into it. It is a shortcut.
