Easy win on Hang Time challenge
In the mission when you must get a high hang time. In stead of doing it the standard way by using jumps in your buggy, get out of you buggy and use the mass invertor it will get you an automatic gold in total hang time (you may have to use the gun more than once) and single hang time.

Glitches
Skip Missions in Hero Mode
You can skip some of the begining missions in hero mode. First, turn on the turbo jetboard secret. Now, use the jetboard to jump from island to island by executing the L1 high jump and a forward flip.

Unlimited/Easy Precursor Orbs
Go to any oracle statue and trade metal head skull gems to start an orb search challenge. Go to the orb and wait for the clock to turn to 00:00.
Even though it says 00:00, it takes another 2nd for the time to run out (I.E. 00:00 is really 00:00.100) So wait one more second, and then press Square to dash at the orb as soon as time runs out and the mission failed screen comes up. You will get 3 orbs, and be able to retry!
