Wow.Can only assume it's the disabled step child of the normal model.
The third new-for-2021 installation is at Ocean Flower Island Fairyland (Danzhou, China). Even more noticeable are the changes to the track design on this model. S&S has shared that China has different G-force requirements, and to meet those qualifications, the track layout has been modified. It should be interesting to well-traveled enthusiasts to see how they can discern the difference in ride experiences.
