During Driver’s License Lunacy, when you have control of Goku and Piccolo/Gohan are support characters, you will need to go to Goku’s house to continue the story. At this time, visit Capsule Corporation and Dr. Briefs will have this substory for you. He is looking to create a new machine, but is missing some parts, so he tasks you with finding a Skull Robo Gear, some Densite and Silver Ore. Before leaving, Briefs mentions that Densite can be found by breaking large rocks. Exit Capsule Corporation to get back to the main region it’s located in and head west from the city.

You may have a little trouble finding the western spot, as it’s at the entrance of a small cave near the water level. When you approach the marker, some robots appear and you will have to do battle with them. These are the same Skull Robos you have been fighting up until now, so don’t expect anything different. Upon defeating all of the robots, you will automatically receive the Skull Robo Gear. If, for some reason, you don’t have the Silver Ore needed for this substory, the same cave where you encountered the robots above has some nodes that should yield some Silver Ore.

Head to the other marker on your map and if you remember Briefs’ words, then you should know what to do. He mentioned that in order to find the Densite, you will need to break large boulders. Now, a “large boulder” is a bit misleading, as you basically want to look for the largest piece of land you can destroy by either using Ki blasts or by charging into it by flying. This should be right where the marker is on your mini-map. Destroy it and amongst the rubble, you should find a purple orb that yields the Densite when collected. Return to Dr. Briefs to finish the substory.
