I don’t know why people say Cuphead and Mugman are not kids when there is proof that they are it has been said several times in its official media.
Imma use one of their latest comic book collections (which is the one I got for my birthday) for most of the example since it’s the latest proof/evidence I got 
I’m just gonna say for starters in the comics, they usually address both boys and sometimes Chalice as “kids” and I know that people would say the word “kid” in general terms when someone is younger than them but in this case I think they are legitimately kids or at least very young teens
Also!! In the first story of the comic, it had Cuphead, Mugman, and Chalice wanting to join the mafia ONLY because they think it would be fun after watching a movie which is something that I would assume a kid would do after watching something interesting, they want to inmate or at least imagine to be the character in the film
Once figure out where the mafia is located, they thought that they were operating a bubblegum operation And didn’t once think about how the mob was (what I assuming) is smuggling rum. Even later in the story, the mob played around with the bubble gum idea.
Also, Cuphead and Mugman are often given chores it seems, not saying that adults don’t do them as well, but typically kids or teens are given chores.
Once they were given the chores, the boys immediately decided to run away because they don’t want to do the chores in the first place.
Adults usually don’t do that, that’s something a child would do that’s their form of rebelling against their parents or guardian. Of course, later in the story they do come back to Elder Kettle to do the chores. Which is something again a kid would do once they realize they don’t want to run away anymore, they come back home.
I wish I could put more examples, but tumblr only has a 10 image limit but you see what I’m trying to say when I think that Cuphead and Mugman are just a pair of young boys, so it’s weird to me whenever I see them being mainly portrayed as adults when there’s a lot of evidence pointing that they are at least somewhat underage.
Well, that’s just my personal opinion, you’re gonna have Cuphead and Mugman be whatever age you want, but that’s just how I see them personally
Anyways, thank you for coming to my TEDTalk
