PTA Problems

Before heading to the bathroom, you can talk to Mackey to start the sidequest “Wasted Cache”. Head to the bathroom to learn a new magic from Randy: the Sneaky Squeaker. After successfully learning it, get the Chinpokomon (Gophermon) on the last cubicle in the bathroom. Leave the community center then go to the South Park Mall parking lot.

After the scene, use the Sneaky Squeaker (SS) to distract the guards then quickly run towards the gate. Once inside, stand on the left where the switch is, then use SS to lure the soldier to the puddle of water. Pull the switch to electrocute him. You may want to wait for the power to turn off before looting the body. Loot the items inside the van then teleport to the rooftop. Don't forget to loot the chest as well. Once done, enter through the vent.

After the scene, you'll be out of the vent but the nazi zombie will kill the two nearby SWAT officers. Defeat the nazi zombie and loot the bodies of the SWAT officers. Head to the conference room next. Loot the cabinets and don't forget to shoot the Chinpokomon on top of the cabinet to the left. (Gunrilla)

Pick up the recording device on the table then leave the building. There will be nazi zombies outside. Defeat them or run away from them.

While you're at it, make sure to visit the police station to start a missable sidequest and friend request by talking to Sgt. Yates.

Once done, report back to Randy to complete the quest and your pic taken with the goth kid's insulting sign and the PTA members. Make sure to talk to all the people here as well to add them to your Friends List.
