Near the launch ramp, there is an array of three flags. Hit all the flags and get a 
level 1 commendation. Do this again and get level 2. Once you get level 3, you will 
get an extra ball. Hit the flags again and get an extra ball again, for an unlimited 
amount of extra balls. Note: The lights for the level commendations disappear very 
fast; be quick about hitting the flags. Be patient and hit the flags. Eventually, 
you will get up to level 3 and be rewarded with extra balls. This method is far 
more successful than the Hyperspace way because you earn them instantly and are 
not required to go down the out lanes, where you can lose the ball while getting 
the other one.
