Template:Lineart
All of the pets on Chicken Smoothie are created from the same line arts (with a very few exceptions). This helps to not only make things easier on the artists, who don't have to create the drawing from scratch each time, but also is the reason why items can fit multiple pets of the same species, and also helps created a unified "style" for the site. Artists are still allowed to make line-edits (alterations to the default outline) but the base is usually still clearly recognizable after the changes.
In a large part, most of the line arts have not been changed since their original releases. The site's creator, Tess, created many of the line arts, but over time other artists have also contributed their own line arts and species to the site!
