In 2014, David was inquired by Ryan Bowman as to whether he wanted to be in Jurassic Shark III: The Revolution, although he refused. He was later offered the role of main antagonist Bread Nelson in the short film Bread's Crumbs. David accepted after being told that his character would kill people, which he deemed interesting. Unreleased archival footage of Bread Nelson was featured in The Biggest Fish of Them All in August.
Prior to the production of the second film, David developed a poor relationship with Ryan, and for that reason became very hateful of Bread's Crumbs. Despite playing the main antagonist of the first film, David declined to reprise the role of Bread Nelson in Bread's Crumbs 2: Electric Boogaloo, although a brief cameo of him was shot at the last minute. Brandon Archibald played Biscuit Savage, the film's new main antagonist who supplanted Bread Nelson. Unreleased archival footage of Bread Nelson was featured in The Conundrum Dimension, which was released in August.
David returned to play Bread Nelson in Bread's Crumbs 3: Scrub Slam via unreleased archival audio, with much of his role having him speak to Nazi Mitch over a phone call. Interestingly, David had more lines in the third film than he did in the first film, all through the use of archival audio.
In February 2017 it was announced that Scrub Slam wouldn't be the final film in the series, and that a fourth film would be created. David M was not expected to reprise the role of Bread Nelson in the film, which made it the first main installment without the character. Nelson briefly appears via a picture, though David wasn't credited for this.
