After a disastrous failed mission, Sonic laments that they can't go back and prevent Robotnik's takeover. Dulcy tells them they can and takes Sonic and Sally to the Floating Island where they find the Time Stones, but in order to time travel to a desired destination/time, they have to synchronize their thoughts and Sonic allows his to drift (to thoughts of chili dogs). They arrive at the eve of the takeover, just in time to see a pristine Mobius and meet Uncle Chuck and their younger selves, but not in time to stop Robotnik (then called Julian) from overthrowing the King.
