RUMOR: Concept art for an underwater portion of Super Nintendo World's Mario Kart ride surface

It looks like we might have a sneak peek at an underwater section for Super Nintendo World's Mario Kart ride, thanks to some concept art. Suzy Riffel worked on designing the Universal Studios Japan Minion Park, and the imagery above was spotted as part of her resume. As you can see, there's no doubt the concept art shows some underwater action for Mario Kart. Whether this design makes it into the final cut for the ride remains to be seen.
