In the first level, go to the place were the three big boulders are that block your way. If you shoot a becon bomb at one and the servbots will climb up and start twiling around dancing!
Just for fun, if you shoot a becon bomb at one of the servebots then the servbot will look confused and will run. Then the other servbots will chase after him! They circle the gustaff about twice or so then stop. Pretty funny!
If you want to get it at the Nakkai Ruins you have to get the Gustaff upgraded a lot. Try some easy levels to get big bucks. (Try the levels that are named "gold city" and "the ruin digging level")
In the bank robbing level, rob the animal hospital then blow it up. In there you will see something that looks like an award get it and you will get 20000 zenny!!!
