In September 2020, with Mad having been reduced to a primarily reprint format, Devlin and Mad artist Tom Richmond announced that they were crowdfunding a book of newly-created movie parodies called Claptrap. They launched their Indiegogo campaign with the completed two-page opening spread for Star Worse: Plagiarizing Skywalker, a spoof of the ninth film in the Star Wars saga. The book will also include takeoffs of older popular or iconic films that Mad had for various reasons opted not to parody at the time of their releases.^[11] The other eleven films are The Big Lebowski, Blade Runner, The Blues Brothers, Citizen Kane, Die Hard, Goodfellas, The Princess Bride, Psycho, The Shawshank Redemption, Toy Story 4 and Unforgiven.

Claptrap was published in 2023.
