The Green Moon is a moon, presumably in the Solar System.
Description
The Green Moon is similar in appearance to the Moon, but green and much smaller. Its soil appears to be made out of easily-liquefying green cheese. The Green Moon is inhabited by at least one, and perhaps several, small green aliens. The only known one is "Cheesy", who, upon witnessing the arrival of a visitor (thought to originate from the planet Barks), threw a glob of cheese in his face.
Behind the scenes
The Green Moon first appeared in 1965 in Astro Pooch.
