it was a normal day in South Park high school... but then there was a loud bang, and suddenly, zombies started flooding the hallway. Wendy and a fee of her friends started to run away, but one grabbed her hair. Nichole thinks fast and cuts Wendy's hair short so they can escape. They managed to make it to a room with a few other and lock the door. Only letting in people they knew were okay, one of which was stan and when he entered, wendy looked up and smiled at him

Wendy: Hey, dude, I'm glad you could make it.
