Dimensional Location: Animated Ghostbusters Universe.

"The PKE Meters are going crazy!" Egon Spengler yelled as the Ghostbusters drive into Gravity Falls.

"Stampeding Civilians Incoming!" Winston Zeddemore screamed as he swerved to avoid the panicking crowds and crashed into a Street Light.

Zombies are swarming towards the Mystery Shack while Love Patrol Alpha are singing together to stop them.

"Wait, that is my voice singing... Stanford, the Time Baby sent us into the past!" Stanley Pines yelled in alarm.

"That might make things worse for us!" Stanford Pines proclaimed fearfully while the Ghostbusters took up defensive positions around their Crashed Vehicle.

The Zombie Outbreak ended and everyone inside Gravity Falls went about repairing the destruction caused by it.

"Stanford, when did you hire the Ghostbusters?" Sheriff Blubs asked Stanley Pines when he recognized him.

"Actually, my Twin Brother brought the Ghostbusters here to see my Mystery Shack. Too bad this Stupid Zombie Outbreak ruined everything." Stanley Pines told Sheriff Blubs nervously.

"I understand how uneasy you feel, the Whole Gravity Falls Police Department is already on edge expecting another attack to happen." Sheriff Blubs admits.

"Maybe the Ghostbusters can help you Patrol Gravity Falls." Stanford Pines offers helpfully while Stanley Pines frowned at his twin brother in sudden confusion.

"Good idea, it might even calm everyone down knowing the Ghostbusters are Investigating Gravity Falls!" Sheriff Blubs proclaimed cheerfully beside Deputy Durland.
