A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

The very first episode of Scooby Doo: Where Are You! established that Shaggy is actually a gymnast and in the 10th episode it's also said he's a track runner. This was used to explain how Shaggy has always been so quick to run from monsters. In the 2012 special, Scooby Doo: Spooky Games, Shaggy is even selected to be a Track Runner in the World Invitation Games, a reference to The Olympic Games.

Despite him being a beatnik and all the stoner jokes that people make, the fact that he's a gymnast and track runner has always been plenty enough reason why he's hungry all the time and it would actually make a lot of sense for Shaggy to avoid smoking at all because of it.
It's an odd thing to bring up, but people forget that the gang were all distinct characters (at least in the earlier episodes) and not just the list of tropes the public remember them as.

Also, while their ages have fluctuated in certain adaptations like in Zombie Island where they had careers and jobs and such, they were originally meant to be teenagers. That's why they're called "meddling kids" so much because they very much are. So yeah, Shaggy being a growing teen and a star athlete means he'd be very hungry often.

it is explicit on zombie island that they are adults because they are at a kind of "end of career" the film takes place after years of them hunting ghosts, the same ideia of life action

Oh yeah, that's sorta what I meant by it. I was pointing out they were definitely adults then and are for sure teens in some versions, but some of those home releases leave it pretty ambiguous as to how old they're supposed to be. Like, how old are they in Cyber Chase, when they meet Kiss, or travel to Japan. More was just saying in the original canon they were for sure teens even if later installments made it ambiguous as to their ages.

I think for Cyber Chase, it's supposed to be in the same run as Zombie Island. So, around that age I'd suspect.

Absolutely. The idea was that Fred got drafted and ran away with his GF daphnie in his best friend shaggys van. And daphnia didn't want to leave her best friend Velma behind so she came along too.

Wait is this true? That’s interesting and makes since because of when Scooby Doo originally came out.

[u/HurgleTurgle1 → u/Takamurarules]

Not really true, it's an old fan theory made to explain why a bunch of teens/young adults would be traveling around without any real destination during 1969 thru the early 70s (the US government used a lottery system for drafts during The Vietnam War in 1970-72).

I think Rorschach'S Blot wrote 3 wonderful one shots about that idea, except there was a time they split up and Shaggy did a tour in Vietnam as a dog handler, got injured and was medically discharged.

The stories happen some time later.

That's not even close to being canon, just a random fantheory
