What is the name of Dick Dastardly's mechanic in the TV series "Wacky Races"?

Dick Dastardly is a fictional character and antagonist who appeared in various animated series by Hanna-Barbera Productions from 1968 onward. Dastardly's most famous appearances are as a main character in the series "Wacky Races" (his initial appearance) and its spin-off, "Dastardly and Muttley in Their Flying Machines".

Dastardly and Muttley flew with two other pilots: Zilly, a coward who would hide in his own clothing when ordered to deploy, and Klunk, the mechanic/inventor, who speaks a language largely composed of strange sounds that only Zilly can understand.

Though he is an expert aircraft mechanic, Klunk typically speaks in vocal sound effects which only Zilly can understand. 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 "Vacation Trip Trap", Klunk became a leader of the squadron when Dick Dastardly went on holiday. In "Home Sweet Homing Pigeon", Klunk is left-handed and illiterate.
