Free Instrument Power

Once you get a Kong's instrument from Candy's Shop, she mentions that using the instrument will 'deafen' (kill) enemies, and even trigger special events for free when played on its own pad. However, if you're running low on instrument power, and you want to use it to kill the enemies in the vicinity but not trigger the event (i.e. in Angry Aztec, if you want to kill the Kremling outside the temple but don't want the bird to swoop down and pick you up), simply stand on the rim of the pad and play your tune. This will trick the game into allowing you to perform the move for free, but not trigger the event.

Note: This only works when the Instrment Pad is designated for the Kong you're playing as.
