Released in the 1990's, Mudflap chronicles Greta's adventures. Each issue had themes like travel and transport, and growing things like sex and food. The emphasis was on fun and free stuff and documents her love of bicycles. Filmmaker Sarah Jacobson wrote of Greta Snider, "...Her films are like her zines, made up of different stories and patchworked together. Even though they are very experimental, they don't bore me like that self-indulgent avant garde shit I was forced to watch in art school."
Mudflap was featured in the Factsheet Five Zine Reader. As well, the zine and the artwork of Greta Snider were featured in the exhibition The Copyist Conspiracy: An Exhibition of Zine Art, held in San Francisco.
