Marvin Monkey is a fictional comic book character.
Not much is known about Marvin Monkey, other than Donald disapproving of Super Snooper comics, instead preferring and endorsing comics that rely plot and character such as Marvin Monkey. On the other hand, Huey, Dewey and Louie consider Marvin Monkey to be "kids' stuff", whereas Donald thinks that that's what Super Snooper is.
Huey, Dewey and Louie eventually discover the quality of Marvin Monkey comics.
Nevertheless, it is clear that Marvin is not as widespread as Super Snooper, the overall references to his comics are much fewer and more contained, than those of Super Snooper's.
- Marvin Monkey is a clear reference to Donald Duck. Like Donald, his anthropomorphic animal race is indicated by his last name, and both Marvin's first and last name, just like Donald, share the same first letter.
- The Super Snooper vs Marvin Monkey plot point is probably a jab at the gradual "replacement" of classic Disney (and therefore, duck) comic book stories by superhero comics during the 1960s and the 1970s.
