Reverchon and Zamperla have constructed a bunch of these spinning coasters. They are typically referred to as "Crazy Mouse" coasters or "Twister Coasters". This is an example of the most common model, the "Twister Coaster 420STD", based on the ride's 420 meter, or 1,378 foot, length. Some other versions of this design are: Crazy Mouse at DelGrosso's Amusement Park, Exterminator at Kennywood, Flagermusen at Fårup Sommerland, Rockstar Coaster at Fun Spot USA, Primeval Whirl at Walt Disney World - Disney's Animal Kingdom (which consists of two side-by-side coasters), and Tyfonen at Tivoli Friheden.
