Larry Larkin is a teenager with many piercings, like Jason Brill. In Rodrick Rules, he does a "performance of carnage" for the talent show. Frank Heffley is shown to despise Larry's piercings, and as such, pokes fun at him; the person who hears the joke, however, is Larry's Father.
Larry makes three cameos, in Dog Days Larry appears when Greg and Rowley did an experiment with money inside the boardwalk, in Double Down he is one of the people in the brain-preserving place. He also appears in The Getaway, where he is shown at the airport taking all his piercings off.
