Not sure if any of the critters in the ride will have clothes. One of the pieces of inspirational art they commissioned from Sharika Mahdi included clothed animal figures with distinctly Splash Mountain-y looking designs. Though I don't know if they're going to use these designs in the ride. The smaller critter band seen in one of the ride's pieces of art didn't have clothes. Just instruments. The larger critter figures (cats, bears, wolves etc) seen in another piece of art were silhouetted in shadow far into the background, can't tell if they have clothes.
