Soos, the handyman of the Mystery Shack was seen walking in the gift shop of the Mystery Shack wearing a hat that had 'Driver In Training" written across the top of it. He also donned an orange and yellow vest over his usual attire. "See you in a few days, dudes!" The slightly overweight man-child announced as he looked over at his fellow employees and friends. He then exited the shop and drove his way over to the local bus company to complete his final round-trip as a part-time bus driver. He picked up a few people who were the passengers for this final ride just as everyone in the town were going to bed.
"Bus 52, departing Gravity Falls, all aboard." The announcement rang all throughout the bus as it departed the small town. Meanwhile, in the dreamscape lay the triangular dream demon with a look of evil intentions in his eye.
"I told 'em everything they loved would change! I gave 'em a fair warning!" Bill Cipher shouted to himself as he paced around from excitement. "Now let's see here..Hmm.."
He floated there, thinking for a bit before an idea popped into his mind.
"I got it!" Bill jumped up in excitement as he was satisfied. "I'll just switch things up a bit. That'll be the perfect revenge for them suckers!"
Bill began to cackle like the psychotic being he is. His hands then grew blue with flames as he made his desire come to be. The good ol' town of Gravity Falls was now surrounded in a dark blue cloud as everything began to change in a rapid pace. There didn't really seem to be much of a change if you witnessed the occurrence from a pretty good distance. However, the change would be witnessed much closer come morning in the possibly forever-changed town of Gravity Falls.
