- Easy duels
While in a duel, keep pushed Z to block and swing the Wii-mote up and down repeatedly until you win. You will block your opponent's hits. When your swing is timed correctly, you will counterstrike a powerful blow. When in duels, your stamina does not decrease so you can keep pushed Z as long as desired. If done correctly, you will not lose any health.

- Gold Idol location in Isla Cruces level
When you get to the waterfall where enemies attack you, defeat them all. Then, walk into the waterfall. Behind the waterfall is a secret room with the Gold Idol.
