Moon Factory 100% Completion
The Moon Factory in Dark Cloud is unlike all previous towns you've come across, first off and most importantly don't trigger the cutscene with Osmond to fly it to the castle before you collect all of the treasures. You'll lose the treasures if you do. Second off and the thing that makes it different than all previous towns is you don't have a town to build but a giant robot instead.
There are no villager requests however you will need to construct the robot properly which isn't too hard at all. If you're having trouble with the order of parts Osmond has a demonstration in his home. Otherwise... Of course the purpose of this guide is to show you the proper layout!
