Call the Banners (1) Token | Walkthrough South Park: TSoT Guide

You cannot walk past the guard

Head to Token's house. You find out that the security guard will not let you in that easily and will use gas against you. You are going to need a gas mask. You can buy one in Jimbo Gun's for 2$ (if you are not carrying any money sell some rubbish or ransack nearby buildings). Go back to the security guard with the mask (note, that you have to put it on, it is not enough to just carry it in your inventory). Since he cannot use gas against you anymore, he will resort to more direct enforcement measures.

Defeat your enemy

Since the opponent has a lot of armour points, it is best to use heavy attacks and special abilities. If needed, remember that Butters can heal you up. Once defeated, the guard will drop a baton of 2nd level, which you will most likely equip instead of the weapon bought in KKK. Having won, you may simply walk to the door and tell Token what happened. You can find a couple of hidden treasures around his backyard, so it is worthwhile to look around before leaving the area.
