|Facts:||Primeval Whirl is really two distinct roller coaster placed side by side. Since they are completely independent of each other two entries exist in the database.|
The Primeval Whirl differs from the standard Reverchon Spinning Mouse. The Disney version has 4 additional cars and a "hidden" transfer/service track. Rather than a parallel transfer/service track inside the roller coaster's perimeter, the transfer track is at the back of the ride and moves the trains into a hidden service area behind the ride and out of the roller coaster's perimeter.
