Originally opened as the Mystery Warehouse, the ride was completely dismantled in the 2011/2012 off-season to be sold to the Ziegler family. This purchase turned out to be fraud, and Fort Fun quickly reinstalled the ride for the 2012 season. The name of the ride was changed to Secret Stage of Horror, and the queue got an update to include characters from the park's Halloween show. The park's Halloween mascot, Jackie Moon, also appeared in the ride on projection screens.
