===Chapter 1: "One Mysterious Letter"===
Sonic's House, Mobius
Time: 5:00 PM (Mobius Standard Time)
Sonic is sitting back and playing Sonic Unleashed. He then hears the doorbell ring. As he opens the door, he sees nothing but a letter with a Eggman Inc. logo on it. He reads it and this is what it says: "Dear Sonic and friends, your homes will be terminated if you don't come to Gravity Falls tommorrow. Destruction of your houses will be advised. If you don't believe this, you will burn to ashes with your house. Your belongings will be teleported to Cabin 1991, at Gravity Falls. Contact me at 199-667-98-192-02, or go to www.EggmanIndustrialBases.co for more". Sonic was suspicious. He then noticed that his belonging were gone, only leaving old, rusted, 1990's furniture. He rushed to Tails' house to tell him.
