While traveling through the Green Hill of the past, Classic Sonic senses a brief earthquake and is soon attacked by the Time Eater.
A version of Green Hill from somewhere in spacetime would soon after be sent to White Space, devoid of any color and life. Noticing the region after ending up in White Space, Modern Sonic races through this version of Green Hill, which regains color and life after Sonic has finished exploring it. This, in turn, also restores Tails, who had been turned into a statue by the Time Eater, back to normal as well.
