Sonic and Shadow fall into a hole and pass through the barrier that Shadow had made to seal away the monsters of the Underground. It is then that they meet everyone in Undertale after the pacifist events. It's just that after being exposed to the chaos emeralds has made them forget about when the human saved them all and are repeating what they did in the original game all over again! Can Sonic and Shadow make it back to the surface alive or at all? Front picture created by: LilyEsmeraldFox!!!! @LilyEsmeraldFox
