A Snelfu is the main currency of Cyberspace, similar to a dollar. They are shown in both coin and bill forms and are featured prominently in the two-part episode, "The Snelfu Snafu". Each amount the snelfu represents is a different color. Prior to this two-part episode however, all bills were a light violet in color. Other forms of currency such as gold quarters, golden eggs, and donuts are also used, but only in certain sites.
