One of two little green Moon Men from the first and longest story arc of The Rocky and Bullwinkle Show. The “Jet Fuel Formula” storyline (broadcast 1959-1960) concerns the pursuit of a formula for rocket fuel. The two aliens are sent to Earth by their people to prevent an influx of Earth tourists. Gidney has a mustache and Cloyd carries a “scrootch gun.”
Note: Jay Ward’s alien cereal mascot Quisp, introduced in 1965, obviously bears a significant resemblance to Cloyd.
