Hint: See squid:
You can see the squid by turning right off the track immediately at the very start in freestyle mode. If you go out far enough, the squid will take you under and blast you back onto the track.

Play the Loch Ness track in career mode. When you reach the waterfall, hold down the nose of your jet ski so that you submerge. You will pop up in a cave on the other side of the waterfall. Once you reach the start of the course on the next lap, the squid will be waiting there.

Immediately at the start of any race (free ride mode recommended), go straight off the course and enter open water. The music will stop and the squid will grab you and throw you somewhere on the track.
