Shelly is a beige ammonite shell with a black aperture usually seen on the left side of her head, although some artworks depict it on the right side. She has orange blush and two eyelashes underneath her eyes. She wears a sleeveless overall dress with a light brown undershirt with a dark brown dress over it.

“Hey, wanna go find dinosaur bones with me?”
