Past
For an unspecified amount of time, the Skeleton Crew have emerged from the Grim Dead Zone every 50 years on Halloween to haunt the people of Emerald Hill Zone fro the entire day.

Skeleton Crew
During the Halloween of 1998, Tails heard of the tale of the Skeleton Crew from the Emerald Hill Zone Leader, thinking it to be nonsense. However, the fox was soon proven wrong when the ghosts emerged, scaring and terrifying the inhabitants of the zone.

Soon, Tails realized that the ghosts couldn't in fact hurt the people, and could only scare them. Tails then flew above the people, shouting out this information in order to get them to calm down and to not be scared of the Skeleton Crew. The Skeleton Crew were displeased with this, as they wouldn't be able to scare anyone if they knew that the couldn't be physically hurt. They gave chase after Tails, who flew in the Tornado all the way to another time zone. In said time zone, it was midnight, causing the Skeleton Crew to disappear prematurely.
