After some debate over what to do next, you ask your new mechanical friends where the nearest shop might be. They seem annoyed by your continued pestering, and say they never move from this spot so they would have no way of knowing. But if they had to guess, and if it will get you out of their space, the Big Bucks almost certainly have some shops where they hang out. Their prime hangout spot is just past this wall and across Capital Creek, so you should check there. You ask how to get past the wall, and the ATM sighs and says it can let you through the secret door if you solve some more riddles or whatever. It does not seem thrilled about this system.
