I can hope it’s been coated with a dead flat or matte finish silicone, and maybe some “dry brushed” gloss silicone to give the effect of sweat where the hair is longer. But I wouldn’t expect any real fur, just the texture of it. The chances of mold growth or color damage basically prohibit any real fur being used outside. As everyone else has stated though, this will be only a few seconds long scene, so the motion will lend itself to the realism.
Side note: This is a theme park, which is a form of art. Artwork will be criticized and judged, as that’s the nature of observing something that reflects some aspect of the human condition. These rides are moving shows, and they will be critiqued harshly. It’s not detrimental to the show to do so, as long as it’s done fairly (this isn’t twitter, after all). To point out sidewalk color or the texture of fur or anything meticulous is important! These discussions inform the cutting edge nature of the industry. We expect a level of realism that simply was not there 20 years ago, so these standards are worth upholding within reason.
