Super Nintendo World, the latest addition to Universal Hollywood’s theme park, is set to open in just a few weeks, giving Mario fans the opportunity to step into a vivid recreation of the Mushroom Kingdom, packed with sights and sounds they know and love.

Not all of them, however, will be able to experience the featured attraction Mario Kart: Bowser’s Challenge, as it has a very specific requirement: Your waistline must not be 40 inches or larger.

“Nothing but wonderful things to say about Super Nintendo World except this,” opens one tweet from YouTuber and “Food influencer,” Rocco Botte, “the body size limitations on the Mario Kart ride are absolutely ridiculous.

According to CDC statistics cited by Healthline, the average clothing size for adults assigned female at birth hovers between 18 to 20.

As many replies to the tweet above indicate, a 40-inch waist is a “very normal and common size to be for many body types.” And Mario Kart: Bowser’s Challenge isn’t the only ride with such strict limitations.

The waistline requirement particularly stings as Mario Kart: Bowser’s Challenge is the only ride to be featured at Super Nintendo World, yet it’s not designed to accommodate average or plus size attendees’ physical dimensions.
