Krentz is a living piece of limburger cheese and the captain of the royal guard of the Moon, who appeared in the 1960 Popeye the Sailor episode "Hits and Missiles". As a limburger cheese-person, he and his fellow limburgers must always keep their bodies under glass domes, as their smell is so rancid it can knock out anyone around them instantly, making their kind very effective guards despite their small size.
