"The PKE Meters are still getting strange readings." Egon Spengler says while the Ghostbusters walked around Gravity Falls together investigating the town.

"Welcome to Greasy's Diner, I'm Lazy Susan. What can I get for you?" Peter Venkman smiled at her as the four Ghostbusters order their Bacon and Eggs.

The Ghostbusters sat down and started eating their breakfast while Sheriff Blubs helped repair their wrecked vehicle for them.


"Alright guys, this is it. Remember, whatever happens down there, we tell no one." Dipper Pines tells his friends.

"Oh no, the kids just entered my underground bunker! The Shapeshifter might still be in there!" Stanford Pines proclaimed fearfully before following them with Stanley Pines right behind him.

"This is incredible! It's like he was preparing for a disaster. But, what kind of disaster would need supplies for over sixty years?" Dipper Pines asked before Stanford and Stanley burst into the room.

"Wait, what! Double Grunkles?" Mabel Pines proclaimed in amazement.

"Mister Pines?" Soos asked in confusion.

"Boss?" Wendy questioned.

"Everyone is coming back to the Mystery Shack to meet my twin brother right now!" Stanley Pines proclaimed loudly.

"Ok, did anyone else know about Grunkle Stan having a Twin Brother?" Dipper Pines asked everyone rhetorically as they walked back towards the Mystery Shack where a Third Grunkle Stan looked up in shock at them.

"Three Grunkles? Am I dreaming this?" Mabel Pines asked everyone worriedly while Stan Pines fainted.

"Stanley, get a cup of water for your past self to drink!" Stanford Pines orders.

"I'm on it!" Future Stanley Pines yelled as he enters the Mystery Shack while everyone stared speechlessly together in bewilderment.

"What is going on here?" Dipper Pines demanded in frustration.

"What is happening here is Time Travel." Stanford Pines explained.
