To get Easy Gold, you must go to the Crash Site (Where the Dwakels are) then go to Tarvarya
and take her first three (3) quests [Quadrolithium, Dam Balloons and Bumper Bolts quests].
All you have to do is kill the Dwakels around (It is easier if you just kill the Dwakel 
Blaster, it's easier because it's health is only 1,000). After getting 8 Quadrolithium, 4 
Dam Balloons, and 6 Bumper Bolts, go back to Tarvarya and "Turn In" to her quests (which 
you have just finished). You will get the rewards [Oculation Helm, Battery Cell Pack, and 
Spybot]. You can sell them for 2,500 Gold each, also, if you encounter a Dwakel Bubble 
Helm (or whatever it was), you can also sell it for 1,250 Gold!
