It was Roadrunner Express at Six Flags New Orleans. It journeyed to California to open as Mr. Six's Dance Coaster in 2010. Plans were put off for it to finally debut as Roadrunner Express in 2011. Magic Mountain announced that the new family coaster would be unveiled to the public this Saturday, May 28; Memorial Day Weekend. Testing has been in progress for a few days now, and the official entrance sign has been placed. No work on the queue or line yet, but the station is being worked on.
