Where can I find soap?
Solution 1:
I was watching a Markiplier video of this game, and inside the Fricker Gang's hideout, one of them is bathing in a bath tub and appears to be taking a nap. If you approach the guy in the tub and talk to him, one of your options is "Pssst. Can you pass the soap?" After selecting this option, you will be given a bar of soap.
I'm assuming if you chose a choice that involved killing the guy in the tub, or letting the Sherf take him, you won't be able to get the soap from him.
