Fourbie Trick
In case some of you do not know what the Fourbie is, it is the red truck
that you use to go places. There is a trick to get opals while riding the
Fourbie. It only works once per game. Not game as in the entire disc, but
game as in a single file. The trick is to hold down the R2 button while
driving on the road in the Fourbie and hold the the left analogue stick to
the left or right. It doesn't matter which way you hold it though, as long
as it makes the Fourbie turn in circles. After a few seconds of spinning,
you will get some opals. You can use opals to buy stuff. Enjoy this nifty
little trick!
