Crafted Yoshi is Smash Ultimate looks utterly dreadful. They went for plush material, but the result looks like studded vomit. They shouldn't have attempted plush shaders, especially not in a game render engine that's far from capable of reproducing plush fabric. At a distance, it doesn't look any different from normal Yoshi because the normal maps are far too fine to be viewed, but up close, it looks like the developers took some image noise, made it a normal map and just applied it all over the body with little care how deformities would stretch the texture.
The render itself does imitate the fabric better, but they also did a hatchet job. They kept the eyes, mouth, shell, and shoes "the same" while the rest gets a fabric and the result looks like a cheap Photoshop job that doesn't convey a 3D model but more of a lazy cropping job. The clashing between the "nonplush" and the "plush" is so jarring, it flattens the image.
The alt is a thoroughly bad idea and I don't see any reason they would opt for it aside from advertising a game barely anyone talks about.
