Klunk is an inventive designer. Each episode sees him developing aircraft or weapons (often missiles which home on some bizarre trait, such as a person sneezing) with odd features and attachments designed to catch Yankee Doodle Pigeon. In episode Vacation Trip Trap, Klunk became a leader of the squadron when Dick Dastardly went on holiday. As it is shown in episode Home Sweet Homing Pigeon, Klunk is left-handed and illiterate ("How do you spell 'X'?").
